Known Issues

The following table lists the known issues in this release. You can reference known issues by Service Request ID 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-Cz9.3.0 Build Notes.

ID Description Severity Found In
37431251 When operating over the Acme Packet 4600, 6300 and 6350 platforms in HA mode and using BFD, the primary BFD interface on the active will not come up. Note that the virtual interface on the active and the secondary interface on the standby do come up. But this is not useful for BFD until the primary session on the active SBC comes up.

Due to this, BFD can't be used to perform switchover between active and standby, as switchover happens only when primary session of BFD goes down. It is recommended not use BFD when operating HA deployments over the ACME Packet 4600, 6300 and 6350.

37522199 ACLI is allowing the configuration of max-signaling-packets under media-manager to exceed the actual max-signaling-rate a system capacity allows. 3 S-Cz9.3.0p5
37211703 TLS client and server negotiates EC (elliptic curve) named curves in supported_groups extension. With this fix, SBC uses the blow named curves:
  • x25519
  • secp256r1
  • x448
  • secp521r1
  • secp384r1

Note:

Earlier SBC versions used only secp256r1.

37135255 On large scale VMs with 12 forwarding cores, the last 2 cores do not take any traffic. Traffic is thus balanced between the first 10 forwarding cores. 2 S-Cz9.3.0
35782870 If routes with both TCP and UDP are available, then the Initial transport method used is UDP. If a failure or timeout occurs, the subsequent transport method of TCP is used in response to a UDP INVITE. If this transport method is selected, then INVITEs are always sent via UDP as long as a response is received.

If a route is available with only one transport method selected (either UDP or TCP) only that transport method is used.

36344739 When deployed as a vSBC in HA mode and processing transcoding calls, the SBC, after a reboot or an HA switchover, may enter a state wherein a single core begins to process all calls rather than load balance them.

Workaround: Perform a manual HA switchover making the affected system the new stand-by. Next, reboot the new standby to get back it into the correct state. Finally, perform a second manual HA switchover to make the new standby active again. This last step is required because the original standby may have synchronized itself with incorrect data.

3 S-Cz9.3.0
36195612 When generating RADIUS CDRs, the Acme-TerminatingTrunk-Group and Acme-TerminatingTrunk-Context fields are missing in the Start, Interim-Update, and Stop CDRs. 3 S-Cz9.2.0p5 and S-Cz9.1.0p10
35641698 When supporting IPSEC tunnels using IKEv1 in initiator mode, and when the endpoint initiates an Security Association renewal sequence (rekey/refresh) over the connection, the SBC can lose connectivity to that endpoint after an HA switchover. This behavior can be considered rare because the SBC is configured as the initiator.

Workaround: An example scenario that causes this behavior is when connection rekey requests come from the endpoint. This can occur because the rekey timing configuration on the endpoint is shorter than that of the SBC. A workaround for this scenario is to manually configure rekey timing such that the SBC always issues the rekey request.

3 S-Cz9.3.0
36001121 The suppress-hold-resume-reinvite feature does not work if the applicable Hold and Resume Re-INVITEs do not include SDP. 3 S-Cz9.3.0
35815496 With Virtual SBCs, registration and calls work fine initially when running IMS-AKA, however, they may stop accepting registrations over TCP after multiple refresh registrations. 2 S-Cz9.2.0p2
35038085 If an exiting audio stream is interrupted by a stray SSRC within the flow's packets, this interruption may trigger one-way audio wherein the audio towards the called party fails. You can confirm this condition by locating RTP packets in the flow with stray SSRC. 2 S-Cz9.1.0
33600407 When you add IPv4 and IPv6 addresses consecutively on the hip-ip-list and icmp-address of the same network-interface, followed by save and activate, the system eventually activates the configuration change but the SBC goes into an unsteady state with the following 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. For example, activate the first config change or addition and then add and activate the second configuration change.

2 S-Cz8.4.0
33190562 On the AP3950 and AP4900, in < 0.1% of reboots, the platform gets stuck and does not reach the ACLI prompt.

Workaround: Perform a power cycle to successfully reboot the system.

2 S-Cz9.0.0p1
When operating over the Azure platform, the SBC displays an inordinate number of kernel messages during the bootup process. You can safely ignore these messages. 3 S-Cz9.0.0
32077115 For Hairpin and Spiral call scenarios, the hide-egress-media-update parameter under media-sec-policy is not supported.

In addition, you must reboot the SBC when you change the hide-egress-media-update parameter under the media-sec-policy, inbound subelement. This parameter is not RTC supported.

Oracle recommends you use the hide-egress-media-update parameter under the realm-config only.

3 S-Cz9.0.0
32565921 The acquire-config process is unsuccessful when your configuration includes an acp-tls-profile. The system does successfully synch the profile after establishing HA.

Workaround: Disable your acp-tls-profile on the active system before performing an aquire-config procedure. Re-enable the profile after aquire-config completes successfully.

3 S-Cz9.0.0
None This version does not support the enhancement to SMP-Aware Task Load Limiting, which adds a second parameter to the sip-config load-limit option. N/A 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

Oracle qualified the QSFP interface for the OCSR operating over the Oracle X9-2 platforms 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 you configure 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
29170419 In long call scenarios, the SBC does not send the expected refresh before the Session-Expires: header value time is up for SUBSCRIBE messages. 2 S-Cz8.2.0

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.
