ID Description Severity Found In
37677691 When upgrading vSBCs running over KVM, Vmware or cloud deployments to release S-Cz930p5 or later (including S-Cz10.0), spaces in the interface-mapping labels can corrupt the interface-mapping list and cause some media interfaces to fail after the upgrade.

Workaround: If you have configured labels to your interface-mapping list entries, remove any blank spaces from them before you upgrade. If you have already upgraded, you can edit your interface-mapping labels so that there are no blank spaces in the label and reboot.

37431006 After running the restore-backup-config command, you must reboot your system to make sure all the non-RTC configurations are applied properly. After this reboot, traffic can be started. 3 S-Cz10.0.0, S-Cz9.3.0, S-Cz9.2.0
37243688 When operating with the AMR-WB codec over the Acme Packet 4600, 6350, 1100 and 3900 platforms, you may find that the system is not able to transcode some DTMF tone signals to RFC 2833 packets.

This issue is also limited to very specific integration deployments. Contact Oracle Technical Support to verify you are experiencing this issue.

2 S-Cz10.0.0
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.

This issue pertains to upgrades to SCZ930GA and later releases that are configured as HA and have Lawful Intercept enabled.

During an upgrade of HA system with LI enabled, after failing over the newly upgraded system (switching over the standby system that has just been upgraded and making it active), the active system (running the upgraded release) crashes. SCZ930p4 includes a work around for this issue, which is detailed in KM Doc ID 3057846.1.

If upgrading to SCZ930p4 or later, and systems have Lawful Intercept enabled and are configured has HA, please refer to this document prior to upgrading.

2 S-Cz9.2.0
37211703 TLS client and server negotiates EC (elliptic curve) named curves in supported_groups extension. With this fix, SBC uses the below named curves:
  • x25519
  • secp256r1
  • x448
  • secp521r1
  • secp384r1

Note:

Earlier SBC versions used only secp256r1.
2 S-Cz9.3.0p3
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.
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
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 Session Router 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 SBC 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 SBC 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.
