Known Issues
The following table lists the known issues in version S-Cz8.4.0. You can reference known issues by Service Request number and you can identify the issue, any workaround, when the issue was found, and when it was fixed using this table. Issues not carried forward in this table from previous Release Notes are not relevant to this release. You can review delivery information, including defect fixes in the S-Cz8.4.0 Build Notes.
ID | Description | Severity | Found In | |
---|---|---|---|---|
34223317 | 3 | |||
31162394 | Running SIPREC on the
Acme Packet 4600 over 1G interfaces may result in system
instability.
Workaround : Do not egress traffic out of a physical interface that exceeds the bandwidth of the physical media capacity. You should determine the amount of egress media traffic and the amount of intercepted traffic on that interface. The intercepted traffic could be any recorded traffic on the interface like (SIPREC, LI, and remote packet trace). |
3 | S-Cz8.4.0 | |
33600407 | When IPv4 and IPv6 addresses are added consecutively on the hip-ip-list and icmp-address of same network-interface, followed by save/activate, the configuration change is eventually activated but the SBC will get into unsteady state, followed by below events on the console:
unregister_netdevice: waiting for <interface:id> to become free.Usage count = 1 Workaround: Add IPv4 and IPv6 address on the hip-ip-list and icmp-address separately and activate them individually i.e. activate the first config change/addition and then add and activate the second config change. |
2 | S-Cz8.4.0 | |
32939208 | You cannot set the SBC
ikev2-ipsec-wancom0-params parameters using
SDM due to issues with the configuration of the
rekeyfuzz and
localip parameters. Note these parameters
have defaults or "0" and "empty" respectively. You can, however,
configure these values from the SBC .
You cannot set the OCSBC ikev2-ipsec-wancom0-params via SDM due to issues in configuration of parameters rekeyfuzz and localip, which have defaults or "0" and "empty" respectively, using OCSDM. Furthermore, if you change the values for rekeyfuzz and localip, you cannot change them back to their defaults. Workaround for changing these parameters' values back to their defaults:
|
3 | S-Cz8.4.0 | |
None | This version's enhancement to SMP-Aware Task Load Limiting, which adds a second parameter to the sip-config load-limit option, is currently not supported. | N/A | S-Cz7.4.0 | |
24574252 |
The show interfaces brief command incorrectly shows pri-util-addr information in its output. | 3 | S-Cz7.4.0 | |
26790731 |
Running commands with
very long output, such as the "show support-info" command, over an
OVM virtual console might cause the system to reboot.
Workaround: You must run the "show support-info" command only over SSH. |
2 | S-Cz8.0.0 | |
None |
Re-balancing is unavailable on the OCSLB when running an Acme Packet 6300 as a cluster member. Set the SLB cluster-config, auto-rebalance parameter to disabled to use an Acme Packet 6300 as a cluster member from that SLB. | N/A | S-Cz730 | |
None |
The system does not support SIP-H323 hairpin calls with DTMF tone indication interworking. | N/A | S-CZ720 | |
None |
The SBC stops
responding when you configure an H323 stack supporting SIP-H323-SIP
calls with the max-calls parameter set to a value that is less
than the q931-max-calls parameter.
Workaround: For applicable environments, configure the H323 stack max-calls parameter to a value that is greater than its q931-max-calls parameter. |
N/A | S-CZ7.4.0 | |
None | The system does not support HA Redundancy for H.323 calls. | N/A | N/A | |
27699451 |
Oracle qualified the QSFP interface for the OCSR operating over the Oracle X7-2 platform for a single QSFP port operating in 4-port mode. Specifically, 4 media interfaces successfully map to the second port of the QSFP interface using a Hydra cable as physical connections to 10G switch ports. | 3 | S-Cz8.1.0 | |
26316821 |
When configured with the 10 second QoS update mechanism for OCOM, the SBC presents the same codec on both sides of a transcoding call in the monitoring packets. You can determine the correct codecs from the SDP in the SIP Invite and 200 OK. |
3 | S-Cz8.0.0p1 | |
The SBC dead peer detection does not work with IKEv1. | 3 | S-Cz8.4.0 | ||
28539190 | When operating as a VNF and using Mellanox interface cards, the OCSBC does not use the Host In Path (HIP) configuration to restrict management traffic, Instead the system allows any traffic over the interface. | 3 | S-Cz8.2.0 | |
28617865 | This version of the OCSBC is not supported as a VNF over VMware using Mellanox interface cards. | 3 | S-Cz8.2.0 | |
28819431 | For TSM use case, the ETC CPU load increased 40% over the previous release. | 2 | S-Cz8.2.0 | |
29170419 | In long call scenarios, the SBC is not sending the expected refresh before the Session-Expires: header value time is up for SUBSCRIBE messages. | 2 | S-Cz8.2.0 | |
29546194 | The SBC is unable to maintain 400 or more TSM/DTLS tunnels. | 2 | S-Cz8.3.0 | |
30643522 |
Starting with
S-Cz8.3.0m1p2, Lawful Intercept users cannot modify LI configuration
with the Session Delivery Manager.
Workaround: LI Configuration must be performed through the ACLI. |
4 | S-Cz8.3.0m1p2 |
Resolved Known Issues
ID | Description | Severity | Found In | Fixed In | ||
---|---|---|---|---|---|---|
34223317 | Inbound source address and port is not showing properly in stop CDR when Re-Invite rejected with 4xx response. | 3 | S-Cz8.4.0p11 | S-Cz8.4.0p12 | ||
26323802 |
The 10s QoS interim feature includes the wrong source IP address as the incoming side of a call flow. The issue does not prevent successful call and QoS monitoring. For monitoring and debugging purposes, you can find the source IP in the SIP messages (INVITE/200OK). |
3 | S-Cz8.0.0p1 | S-Cz8.4.0p13 | ||
26497348 |
When operating in HA mode, the SBC may display extraneous "Contact ID" output from the show sipd endpoint-ip command. You can safely ignore this output. | 3 | S-Cz8.0.0 | S-Cz8.4.0p13 | ||
28658810 | When operating as a VNF and using Mellanox interface cards, the OCSBC does not support any other type of card for media interfaces. (If any media interface uses a Mellanox card, all media interfaces must use a Mellanox card.) | 3 | S-Cz8.2.0 | S-Cz9.1.0 | ||
31828563 | While using STIR/SHAKEN, Acme Packet 4600 performance is capped at 330 CPS, and Acme Packet 6350 performance is capped at 1200 CPS for both dual and quad NIU cards. | 3 | S-Cz8.4.0p2 | S-Cz8.4.0p3 | ||
33434641 | If local-port-match value is set under security-policy, and local-port-match-max is not set, then SBC processes traffic considering full port range. SBC considers the default value of local-port-match-max (i.e. 65535) and applies the specific action mentioned under security-policy to full port range. Configure the local-port-match-max or remote-port-match-max value to set a new port range or set same value for local-port-match and remote-port-match-max to configure a single port. | 2 | S-Cz8.4.0p4 | S-Cz8.4.0p9 | ||
32535426 | The show temperature output will display different values compared to releases older than S-Cz8.3.0. Starting with S-Cz8.3.0, the temperature queries via ACLI and SNMP are reporting more accurate values.
|
3 | S-Cz8.1.0 | S-Cz8.3.0 | ||
29439964 | ACLI Users will receive an error on the output of the show registration sipd by-user command. | 4 | S-Cz8.2.0 | S-Cz8.4.0 | ||
Issue: When upgrading to S-Cz8.4.0p7 from a release prior to S-Cz8.4.0p5, the system does not display templates in Configuration Assistant. Work-around: Run mkdir /code/configAssistant/ before the upgrade. Or, if upgraded already, run mkdir /code/configAssistant/ and cp /var/configAssistant/template-package.tar.gz /code/configAssistant/ You need to do this only once. The folder persists unless you delete it manually. |

32688016 32695177 |
The SBC
incorrectly exhibits the following 2 incorrect behaviors
with the PCRF during Register or Message call flows:
Workaround—You can correct these by setting the diam-rx-strict-compliance option to the applicable ext-policy-server to enabled. When you set this option, you can correct the four issues above so that the SBC performs the following:
|
3 | S-Cz8.4.0p4 | S-Cz8.40p6 | ||
32524837 32524762 32488834 32502583 |
The SBC
incorrectly exhibits the following 4 incorrect behaviors
with the PCRF during Register and Message call flows:
Workaround—You can correct these by setting the diam-rx-strict-compliance option to the applicable ext-policy-server to enabled. When you set this option, you can correct the four issues above so that the SBC performs the following:
|
3 | S-Cz8.4.0 | S-Cz8.4.0p5 | ||
32243204 | STIR/SHAKEN entitlement is not available when system is set up as a Peering Session Border Controller product. | 2 | S-Cz8.4.0p2 | S-Cz8.4.0p4 | ||
32056356 |
While performing VoLTE Accounting on a 3G-to-4G MT call, the SBC incorrectly populates VSA ID 69 with the P-Asserted-Identity (PAI) retrieved from the response. This identifies the called side. Within the context of a mobile terminating call, the SBC should be identifying the caller, populating this VSA with the PAI retrieved from the INVITE. Workaround—You can correct this by setting the unidirectional-p-asserted-id option in the applicable account-config to yes. |
2 | S-Cz8.4.0 | S-Cz8.4.0p4 | ||
31812964 31926021 31918592 |
The SBC incorrectly exhibits the following 3 incorrect behaviors with the PCRF during Register and Message call flows:
Workaround—You can correct this by setting the diam-rx-strict-compliance option to the applicable ext-policy-server to enabled. When you set this option, you can correct the three issues above so that the SBC performs the following:
|
3 | S-Cz8.4.0 | S-Cz8.4.0p4 | ||
28618563 |
The system is not populating the Username AVP in Accounting Requests (ACRs) correctly. When triggered by an INVITE, these AVPs contain only the "@" sign. They do not include the username and domain name portion of the URL. | 3 | CZ8.1.0m1 | S-Cz8.4.0 | ||
31163030 | In VOLTE deployments with registration refreshes, you may see unusually large numbers in the alloc and usage count fields while executing the show buffers command. This is a known statistics accounting issue. | 4 | S-Cz8.3.0 | S-Cz8.3.0m1p9 | ||
31315823 |
When running IMS-AKA over UDP on virtual SBCs, IMS-AKA registrations may not succeed. Registration failure can also cause associated calls to fail. Oracle has observed this only happens after a system reboot. Oracle has also observed that performing a Save and Activate command sequence after a reboot ensures these registrations are successful. If you are running IMS-AKA over UDP on virtual SBCs, perform a Save and Activate command sequence after system reboot to ensure successful IMS-AKA registrations. |
3 | S-Cz8.4.0 | S-Cz8.4.0p3 | ||
32181987 | Do not copy/paste
characters into a configuration menu and attempt to edit the
copied text. This applies to both console and SSH sessions.
Workaround: Edit the data before copy/paste. |
3 | S-Cz8.4.0 | S-Cz8.4.0p3 | ||
32534935 | Media is not resumed after RBT playback for transcoded calls on vSBC. Avoid upgrading to releases where this bug is open if your deployment uses a vSBC with Transcoding and is configured to use Ringback-Trigger values. | 3 | S-Cz8.4.0p4 | S-Cz8.4.0p5 | ||
32517222 | sipd crash while processing 200 OK of reINVITE. The SIP process can crash (and failover in an HA pair) while processing 200OK on the reINVITE in certain scenarios involving media-sec-policy configurations. See the build notes for more details. | 2 | S-Cz8.4.0p4 | S-Cz8.4.0p5 | ||
30794993 | Please see the section on Upgrades For Configurations that Include Signaled IPSec Tunnels and LI Configurations in Upgrade Downgrade Caveats in this document for an explanation of this issue. | 3 | S-Cz8.4.0 | S-Cz8.4.0p2 | ||
31726575 | Do not configure sip-advanced-logging if you expect any auth-invite call flows (401/407). If you are upgrading to S-Cz8.4.0p2 or later, and your configuration includes conditional logging (session-router, sip-advanced-logging, state=enabled), you must first remove sip-advanced-logging from the config, otherwise calls will fail.
|
2 | S-Cz8.4.0p2 | S-Cz8.4.0p4 | ||
32049267 | Do not configure AEAD_AES_256_GCM cipher in the sdes-profile, crypto-list parameter, or the system will crash. | 3 | S-Cz8.4.0p3 | S-Cz8.4.0p4 | ||
The Acme Packet 6350 with Quad 10Gbe NIU is unable to maintain 375,000 or more idle TSM/DTLS tunnels. | 3 | S-Cz8.3.0p2 | S-Cz8.4.0p2 | |||
30794993 |
The SBC might display an excessive number of debug messages after an HA switchover, if you configured both X123 LI and IKEv2/IPSec with IPv6 security policies. You can safely ignore these messages. |
4 | S-Cz8.4.0 | S-Cz8.4.0p2 | ||
31384643 |
During the testing of this release Oracle identified a pre-existing issue in the code where adding an LI warrant during a period of heavy SIP load may cause the system to stop responding, which results in a switchover. This issue exists in prior releases and will be addressed in an upcoming 8.4 patch. If you have not encountered this issue in the past, it is unlikely that you will encounter it now. System Impact: If you add an LI warrant while the SBC is under heavy load from SIP traffic, a mid-call intercept operation may not occur after the addition (causing the SBC to stop responding). If the SBC stops responding a switchover will occur, but the warrant will have been added correctly. The issue can be mitigated by performing addition of LI warrants during off-peak times, such as maintenance windows. |
3 | S-Cz8.4.0 | S-Cz8.4.0p2 | ||
30520108 |
Upon registering 100k or more IMS-AKA user registrations, and handling large numbers of VoLTE calls and registration refreshes, in excess of 8k for example, a vSBC may hang. At this point, you would find the vSBC unresponsive and inaccessible. An example of conditions when this may occur includes:
Reboot the system from the hypervisor to recover from this issue. |
S-Cz8.3.0m1p5 | ||||
30364057 |
Do not use DNS for
multiple services on the OCSBC simultaneously. DNS service
operates on the OCSBC normally when you configure it for a
single purpose. When you configure it for multiple purposes,
however, lookups do not complete correctly.
Workaround: An example of this would be configuring DNS for both PCRF and ENUM services. You can mitigate this issue by configuring the local routing table with ENUM lookups. |
3 | S-Cz8.3.0p7 | S-Cz8.3.0m1p5 | ||
29862440 |
When transcoding from T.38 to G711FB, the OCSBC includes multiple (for example 2) m-lines in the SDP when there are multiple (for example 2) c-lines in the source SDP. This happens even if you have set the fax-single-m-line parameter in the applicable codec-policy to present a single m-line. Workaround: Configure an ingress HMR to remove all but 1 c-line from the incoming SDP. |
3 | S-Cz7.4.0m1p8 | S-Cz8.3.0m1p3 | ||
30158557 |
Under high media loads that include AMR/AMR-WB to PCMA transcoding, the 10G port on the Acme Packet 6300 is experiencing packet loss and, therefore media MOS degradation. | 2 | S-Cz8.1.0m1p16 | S-Cz8.4.0 | ||
30444535 |
When configured for the minimum TCP disconnect time, the default for network-parameters, the OCSBC takes an unexpectedly long time before attempting to create a socket and connect. When using the defaults to create and connect using the minimum amount of time, this process takes 18 seconds instead of 9. | 3 | S-Cz8.3.0m1p3 | |||
29846828 |
The OCSBC stops generating registration refreshes after 12 hours for Surrogate Agents. After a reboot, the OCSBC attends to registration and refreshes correctly using the new Call ID for 12 more hours. | 2 | E-Cz8.1.0m1p8 | S-Cz8.1.0m1p22 | ||
30330778 |
The OCSBC cannot forward a call that uses a TEL-URI and includes the routing number (rn) parameter. Depending on your routing configuration, the OCSBC may reject these call with a 404 Not Found/No Route to Destination. The OCSBC forwards these portability scenarios properly when they present an R-URI. | 1 | S-Cz7.4.0m2p4;8.1.0m1p18 | S-Cz8.1.0m1p23 | ||
29779932 |
The OCSBC uses a Diffie Hellman algorithm that conflicts with that of the 10.4 Solaris SFTP server. As a result, both CDR and HDR transfers to these servers fail. Do not use the Solaris 10.4 SFTP server with the OCSBC. |
1 | S-Cz8.1.0m1p9, S-Cz8.3.0p7 | S-Cz8.3.0m1p4 | ||
29913123 |
NMC causes the Acme Packet 6350 to switchover when NMC gets its first traffic match. | 2 | S-Cz8.1.0M1P9 | S-Cz8.3.0m1p3 | ||
29403076 |
When generating HDR reports and SNMP output on resource utilization that includes threads, the OCSBC omits the thread name, leaving the applicable field and OID empty. | 3 | S-Cz8.1.0M1P9 | S-Cz825p3 | ||
310398.2.0 | When mid-call Lawful Intercept is enabled, and the SBC has not started intercepting particular sessions, those sessions will not be replicated on the standby. If a switchover occurs, affected calls could be dropped. | 3 | S-Cz8.3.0m1p2 | S-Cz8.4.0 | ||
28157960 |
When setting up a SIPREC session, the SBC sets up 1-way audio if the far end offers an odd port number in the m line. |
2 | S-Cz8.0.0 | S-Cz8.3.0m1p8 | ||
26669090 |
The SBC dead peer detection does not work with IPv4. | 3 | S-Cz8.0.0 | Could not reproduce - S-Cz8.4.0 | ||
22322673 |
When running in
an HA configuration, the secondary
SBC might go out of
service (OoS) during upgrades, switchovers, and other HA processes while
transitioning from the "Becoming Standby" state. Oracle observes such behavior
in approximately 25% of these circumstances. You can verify the issue with
log.berpd, which can indicate that the media did not synchronize.
Workaround: Reboot the secondary until it successfully reaches the "Standby" state. |
3 | S-Cz7.3.0P1 | S-Cz8.0.0 | ||
29931732 |
The embedded communications monitor probe does not send IPv6 traffic to the Oracle Communications Operations Monitor's mediation engine. | 3 | S-Cz8.0.0 | S-Cz8.3.0m1p4 | ||
30375697 | Infrequently during race conditions, the number of SIP registration entries on the active and standby SBCs differs, with the standby SBC containing fewer entries. When this happens and a switchover occurs, some endpoints are unable to receive calls until the endpoint re-registers. Increase Journal index size and optimize the Journal management code to avoid this. | 2 | S-Cz8.1.0m1p18 | S-Cz8.1.0m1p18b | ||
30544663 | When a session
add action is executed and the session is not found in the sipProxy, a new Sip
Session and two Sip Dialogs are created and cross referenced and the buffer
from the active is loaded. If the load fails, the update function exits and the
SipSession and SipDialogs are left dangling and create a memory leak.
Workaround: To avoid this memory leak, successfully load the buffer BEFORE creating the session and dialogs. Monitor the standby SBC's memory usage and reboot as needed. |
3 | S-Cz8.1.0m1 | S-Cz8.1.0m1p18b | ||
30498837 | A sipd process
crash occurs with a signature containing the following:
The SBC can leak File Descriptors in cases where there are
certain process errors. For example:
This does not trigger proper closure of sockets. This is avoided by closing the socket that was opened and then setting an error identifying exact error code. |
2 | S-Cz8.1.0m1p18 | S-Cz8.1.0m1p18b | ||
29403076 |
The "thread-event" and "thread-usage" HDR categories are displaying incorrectly due to MBCD and SIPD thread names not properly writing into the files and OID output. MBCD and SIPD now properly assign and pass the proper names. |
3 | S-Cz8.1.0m1p9 | S-Cz8.1.0m1p18b | ||
29633588 |
During certain configuration activities, the SBC restarts due to an issue caused by improper configuration steps being processed in the sip-manipulation, header-rules. The SBC now returns an error message stating "Invalid Selection" instead of failing. |
3 | S-Cz8.1.0m1p11 | S-Cz8.1.0m1p18b | ||
29937232 |
GW unreachable and NetBufCtrl MBUFF errors - This can result in system instability including crash, gw-unreachable and redundancy issues. System will switchover if in HA. Show Buffers output will normally show an increase of errors reported in the NetBufCtrl field due to mbuf’s not being freed. |
2 | S-Cz8.3.0 | S-Cz8.3.0p6 | ||
288.2.0258 | On VNF
platforms, when running TLS Chat on VMware-PV 4core (SSFD) + 16GB, TLS Chat
sessions are gradually decreasing. When looking in Wireshark at EXFO, EXFO
forwards a wrong TLS MSRP Chat payload to EXFO UAS.
TCP Chat does not have this error. |
3 | S-Cz8.0.0 | S-Cz8.3.0m1p2 | ||
For Advanced Media Termination deployments using the 4600, 6300, 6350 platforms, the SBC is generating RTP and RTCP on the ports 20000 and 20001, instead of generating both on the same port 20000. | 3 | S-Cz8.3.0 | S-Cz8.3.0m1p2 | |||
29522609 | Some calls that are configured to generate ring back tones result in one-way audio. | 2 | S-Cz8.3.0 | S-Cz8.3.0m1p2 | ||
29558827 | IMS-AKA calls running over IPv6 networks which utilize VLANs on systems with Mellanox network interfaces may experience one-way audio. | 3 | S-Cz8.3.0p3 | S-Cz8.3.0m1p2 | ||
29580506 | SBCs running on virtual platforms or the Acme Packet 3900 could switch over when running IMS-AKA calls involving refresh registrations. | 2 | S-Cz8.3.0p3 | S-Cz8.3.0m1p2 | ||
29607573 | The SBC is unable to successfully initiate a TCP connection to configured Diameter Accounting (Rf) servers. | 2 | S-Cz8.3.0 | S-Cz8.3.0m1p2 | ||
30114764 |
When presenting the content type for SPIROU during SIP to SIPI interworking, the SBC is displaying the text base=spirou. Based on relevant standards, it should display base=itu-92+ as the content type. | 4 | S-CZ8.3.0m1 | S-Cz8.3.0m1p2 | ||
30127762 |
When performing SIP to SIPI interworking, the SBC is not including an ISUP REL in the interworked body of its 400 Missing CSeq message when it rejects applicable calls from the SIPI side. | 4 | S-CZ8.3.0m1 | S-Cz8.3.0m1p2 | ||
30240798 |
The OCSBC closes connections when using some SFTP clients, including WinSCP and MOBA, to upload files over 200KB. Workaround - Use the Linux or Filezilla SFTP client when uploading files greater than 200k. |
3 | S-CZ8.3.0p6 | S-Cz8.3.0m1p2 | ||
30289027 |
Azure does not
always properly reset media interfaces after the OCSBC reboots. Instead, Azure
sometimes tries to process a non-existent packet as soon as the OCSBC comes
back up, resulting in a kernel panic.
Workaround - If you experience a kernel panic after OCSBC reboot, stop and restart the vSBC from the Azure UI. |
3 | S-Cz8.3.0 | S-Cz8.3.0m1p2 | ||
30453532 |
The Web GUI available in the S-Cz8.3.0M1 release cannot adequately be used to configure the Enterprise SBC. Workaround: For Web GUI support, use releases either prior to S-Cz8.3.0M1, or releases S-Cz8.3.M1p2 and later. |
2 | S-Cz8.3.0m1 | S-Cz8.3.0m1p2 | ||
26258705 |
The show sipd srvcc command does not display the correct number of unsuccessful aSRVCC calls. | 3 | S-Cz8.0.0 | S-Cz8.3.0 | ||
28617938 |
The
anonymize-invite
option for CommMonitor is not RTC. To see a change, you must either reboot or
toggle the admin state. The following is a general admin state toggle
procedure:
|
4 | CZ8.1.0m1 | S-Cz8.3.0 | ||
29556215 | The SBC does not send SIPREC data to a remote call server. | 2 | S-Cz8.3.0 | S-Cz8.3.0p5 | ||
29608499 | In all documents except for the Release Notes and Installation guide, the printed version of this release (S-Cz8.3.0) is incorrectly displayed as S-Cz8.2.0. | 4 | S-Cz8.3.0 | S-Cz8.3.0p3 | ||
28539155 | When operating as a VNF and using Mellanox interface cards, the OCSBC does not support ICMP over IPv6. | 3 | S-Cz8.2.0 | S-Cz8.3.0 | ||
29322490 | The SBC intermittently does not process the registration (Event: reg) of a SUBSCRIBE with Expires header=0 that should be created after receiving a NOTIFY with a termination request from a UE. | 2 | S-Cz8.2.0 | S-Cz8.3.0 | ||
28526228 | Maximum SRTP capacity on VNF platforms is 25% lower than in the S-Cz8.1.0 release. Expected capacity will be restored in a follow up patch. | 3 | S-Cz8.2.0 | S-Cz8.3.0 | ||
28679339 |
When supporting SRVCC roaming calls, the OCSBC is handling SRVCC end-station de-registration events by properly including associated URIs in the 200 OK. It is not, however, saving those associated URIs in its registration cache.

28610095 |
In some circumstances, and with add-sdp-invite and add-sdp-profile configured, the SBC does not include the original SDP in a Re-INVITE that has no SDP. This does not comply with RFC 3264. Instead, the SBC inserts the negotiated media information from the last successful negotiation as the ReINVITE's SDP offer and sends this ReINVITE with inserted SDP to the next hop signaling entity. This issue is evident by the contents of the SDP o line. | 3 | S-Cz7.4.0 | S-Cz8.3.0m1 | ||

On Virtual platforms, the OCSBC is not forwarding traffic transcoded to EVS or Opus codecs if you have configured the applicable policy with a forced ptime of 60ms. |
26559988 |
In call flows that include dual ALTC INVITEs from the callee, and subsequent Re-INVITEs that offer an ALTC with IPv6 video, the OCSBC may not include the m lines in the SDP presented to the end stations during the Re-INVITE sequence. This results in the call continuing to support audio, but not video. |
26598075 |
When running on the Acme Packet 4600, the OCSBC sends a 200OK with IPv4 media address for call flows with offerless INVITES and the OCSBC configured with add-sdp-invite=invite and ALTC configured for IPv6 on the egress. |
ACMECSBC-30710 | When operating as a VNF and using Mellanox interface cards, the OCSBC does not support outbound ICMP. |
23756306 |
When you configure the session-router with an operation-mode of session, it does not correctly clear sessions. |
The SBC can incur a system-level service impact while performing a switchover using "notify berpd force" with an LDAP configuration pointing to an unreachable LDAP server. Workaround: Ensure that the SBC can reach the LDAP server before performing switchover. |

When deployed as a vSBC, configured for IMS-AKA, and operating with registrations exceeding 60k, the OCSBC may exhibit performance degradation, exhibited by high CPU load or system crash. Workaround - Oracle has found that disabling the security-policy sa-lookup-exception parameter allows IMS-AKA to function correctly while supporting a high number of registrations. This parameter is enabled by default. Disable this parameter within all applicable security policies before running IMS-AKA. This parameter, when enabled on Acme Packet hardware, works as designed. |
32062551 | Virtual SBC platforms may incorrectly assess link status thereby causing major health degradation and triggering a failover. |
30595413 | The IKEv2/IPSEC negotiation fails while using TRANSPORT MODE and different IP’s for IKE and SIP interfaces. |
23253731 |
After an HA switchover, the new standby SBC retains some IMS-AKA subscriber TCP sockets. You can clear these sockets by rebooting the SBC. |
29005944 | On Acme Packet hardware in an HA configuration, with a large number of IMS-AKA endpoints, the standby is unable to synchronize, and when rebooted goes OOS. |
27031344 |
When configured to perform SRTP-RTP interworking, the SBC might forward SRTP information in the SDP body of packets on the core side, causing the calls to terminate. Workaround: Add an appropriately configured media-sec-policy on the RTP side of the call flow. This policy is in addition to the policy on the SRTP side of the call flow. |
30520181 |
When performing large numbers of simultaneous registrations, such as during a registration flood, the OCSBC may become unstable and stop responding when it exceeds 200k IMS-AKA subscriber registrations. |
32512333 | If managing with Oracle
Communications Session Delivery Manager (formerly NNC) there is
an updated XSD file required. The following is the patch number
on MOS for obtaining the XSD:

Media interfaces configured for IPv6, and using different VLANs that operate over different infrastructures, including VoLTE and 3GPP, are not supported. |
28639227 | When operating as a VNF and using Mellanox interface cards, the OCSBC does not support SCTP transport. |
28906914 | For transcoding use cases, the G711/G729 codec pair might experience unstable performance when each DSP has greater than 500 transcoding sessions. |
30534173 |
The DSP used by the OCSBC has a vendor firmware defect that causes failures with the T.38 codec. If you are using the T.38 codec, you may experience minimal media losses on those calls. This problem may also cause the OCSBC to reboot. |
N/A | The T.140-Baudot Relay is not excluded from supported features with pooled transcoding. |
N/A | When operating as a VNF deployed in an HA configuration, the OCSBC does not support IPSec. |

Caveats and Limitations
The following information lists and describes the caveats and limitations for this release. Oracle updates this Release Notes document to distribute issue status changes. Check the latest revisions of this document to stay informed about these issues.
Acquire Config and acp-tls-profile
The acquire-config process fails if your configuration includes an acp-tls-profile. The system does, however, successfully synch this profile after HA is established.
Workaround: Disable your acp-tls-profile on the active system before performing an acquire-config procedure. Re-enable this profile after aquire-config completes successfully.
VNF in HA Mode
When the SBC VNF is running in HA mode, any existing IPSec tunnels do not fail over the standby SBC.
Media Policing
The Acme Packet 1100, 3900 and 4600 as well as all software-only deployments do not support any Media Policing configuration.
Toggling SIP Interfaces Running TCP
You must reboot the system any time you disable, then enable an active SIP interface that is using TCP.
Provisioning Transcode Codec Session Capacities
When a transcode codec was originally provisioned in an earlier software version with a license key, a capacity change using the setup entitlements command requires a reboot to take effect.
Virtual Network Function (VNF) Caveats
The following functional caveats apply to VNF deployments of this release:
- The OVM server 3.4.2 does not support the virtual back-end required for para-virtualized (PV) networking. VIF emulated interfaces are supported but have lower performance. Consider using SR-IOV or PCI-passthru as an alternative if higher performance is required.
- To support HA failover, MAC anti-spoofing must be disabled for media interfaces on the host hypervisor/vSwitch/SR-IOV_PF.
- You may need to enable trust mode on the host PF, when using Intel X/XL7xx [i40e] NICs with SR-IOV, before you can use VLANs or HA virtual MAC on the guest VF. Refer to the Intel X710 firmware release notes for further information.
- MSRP support for VNF requires a minimum of 16GB of RAM.
- The system supports only KVM and VMWare for virtual MSRP.
- CPU load on 2-core systems may be inaccurately reported.
- IXGBE drivers that are a part of default host OS packages do no support VLANs over SR-IOV interfaces.
Virtual Network Function (VNF) Limitations
Oracle Communications Session Border Controller (SBC) functions not available in VNF deployments of this release include:
- FAX Detection
- T.38 FAX IWF
- RTCP detection
- TSCF functionality
- LI-PCOM
- ARIA Cipher
Transcoding - general
Only SIP signaling is supported with transcoding.
Codec policies can be used only with realms associated with SIP signaling.
The T.140 to Baudot Relay transcoding support is not available on vSBC or Acme Packet 3900 platforms.
T.38 Fax Transcoding
T.38 Fax transcoding is available for G711 only at 10ms, 20ms, 30ms ptimes.
Pooled Transcoding for Fax is unsupported.
Pooled Transcoding
- Lawful intercept
- 2833 IWF
- Fax scenarios
- RTCP generation for transcoded calls
- OPUS codec
- SRTP and Transcoding on the same call
- Asymmetric DPT in SRVCC call flows
- Media hairpinning
- QoS reporting for transcoded calls
- Multiple SDP answers to a single offer
- PRACK Interworking
- Asymmetric Preconditions
DTMF Interworking
RFC 2833 interworking with H.323 is unsupported.
SIP-KPML to RFC2833 conversion is not supported for transcoded calls.
H.323 Signaling Support
If you run H.323 and SIP traffic in system, configure each protocol (SIP, H.323) in a separate realm.
Media Hairpinning
Media hairpining is not supported for hair-pin and spiral call flows involving both H.323 and SIP protocols.
Lawful Intercept
Lawful Intercept is supported for the X123 and PCOM protocols only. PCOM support for LI is not available on virtual platforms.
Fragmented Ping Support
The Oracle Communications Session Border Controller does not respond to inbound fragmented ping packets.
Physical Interface RTC Support
After changing any Physical Interface configuration, you must reboot the system reboot.
SRTP Caveats
The ARIA cipher is not supported by virtual machine deployments.
Packet Trace
- Output from the packet-trace local command on hardware platforms running this software version may display invalid MAC addresses for signaling packets.
- The packet-trace remote command does not work with IPv6.
Trace Tools
- packet-trace command
- The communications-monitor as an embedded probe with the Oracle Communications Operations Monitor
- call-trace
The verify-config command displays a warning if more than one of these is enabled.
RTCP Generation
Video flows are not supported in realms where RTCP generation is enabled.
SCTP
SCTP Multihoming does not support dynamic and static ACLs configured in a realm.
SCTP must be configured to use different ports than configured TCP ports for a given interface.
MSRP Support
- Workaround: Set the sip-port, address parameter to a different address than where media traffic is sent/received, the steering-pool, ip-address value.
Real Time Configuration Issues
In this version of the SBC, the realm-config element's access-control-trust-level parameter is not real-time configurable.
Workaround: Make changes to this parameter within a maintenance window.
High Availability
- Create the SIP interface or Session Recording Server on the primary SBC, and save and activate the configuration.
- Reboot both the Primary and the Secondary.
Offer-Less-Invite Call Flow
Call flows that have "Offer-less-invite using PRACK interworking, Transcoding, and dynamic payload" are not supported in this release.
Fragmented SIP Message Limitations
Fragmented SIP messages are intercepted but not forwarded to the X2 server if IKEv1/IPsec tunnels are configured as transport mode.
Workaround: Configure IKEv1/IPsec tunnels as "tunnel mode".
IPv6 On X1 Interface
IPv6 does not work on X1 interface.
Diameter Server Timeout during Save/Activate
When saving and activating a configuration, the SBC may disconnect from an external policy server. The cause of this disconnect is based on SCTP HEARTBEAT value configured on the Diameter policy server.
Solution: You can work around this issue by setting the policy server's SCTP HEARTBEAT to a value greater than 750ms, which exceeds the amount of time it takes to perform a save/activate on the SBC.
HA Deployment on Azure
HA deployments on Azure are not supported.
Simultaneous Use of Trace Tools
See "Trace Tools" caveat.
LI and Rx Interfaces using the same Address
Do not configure an X1, X2, or X3 TCP endpoint with the same address as an Rx interface. These configurations create conflicts between the Linux TCP stack and atcpd.IKE
ECDSA certificates are not supported with IKEv2 configurations.
IWF
IWF (SIP-H323) appears at the setup entitlements prompt on virtual platforms when H.323 is not supported.
SIPREC Post REFER Processing
For SIPREC calls that use the Universal Call ID SPL and also exercise SIPREC on main call flow, the SBC does not include UUID in ACK or BYE messages post REFER processing.
Acme Packet Platform Monitoring Caveats
The SFP INSERTED and SFP REMOVED Alarms and corresponding traps are not supported on the following platforms:
- Acme Packet 3900
- Acme Packet 3950
- Acme Packet 4600
- Acme Packet 4900
- Acme Packet 6100
- Acme Packet 6300
- Acme Packet 6350
IPSec Trunking Tunnel Caveat
The setup Entitlements command allows to set a maximum of 2500 IPSec trunking tunnels. Each IPSec trunking tunnel secures signaling and media traffic for more than one SIP session. You can either set a maximum of 2500 trunking tunnels or less, while configuring the session capacity. Setting a maximum value for trunking tunnel does not limit the configured session capacity.
Limitations Removed
The limitations listed in this section are no longer applicable on this version of the SBC.
Remote Packet Trace
Remote packet trace is now supported on the Acme Packet 1100, 3900, and 4900 platforms. It is also now supported over virtual platforms.
IPSec on Virtual Platforms
IPSec functionality including authentication header (AH) support is available on virtual platforms and the Acme Packet 3900.
