SBC was releasing unexpected SIP 408
Hello,
we have an HA pair of 6300 on SCZ8.1.0 MR-1 Patch 12 and from time to time it starts to release 408 messages and we have a lot of calls down. That problem is temporarly resolved by making a switchover until the next time. These SBCs were on version SCZ7.3.0 MR-2 Patch 2 (Build 424) and were advised to upgrade because we were hitting bugs:
Bug 25341569 - Session Agents OOS - Ping answers on wire but not reaching CPU - No ACL drops
Bug 25259125 - Session Agents OOS - Ping answers on wire but not reaching CPU - No ACL drops
Bug 25420175 - Traffic is dropped after deleting dynamic trusted entry by command
