Cisco Bug: CSCuq98155 - IPV6 calls across sip trunk fails
Jul 03, 2017
- Cisco Unified Communications Manager (CallManager)
Known Affected Releases
Symptom: IPV6 calls across sip trunk fails. Call manager does not respond to 180/200 OK/BYE message. Conditions: We can see "Unexpected end of string" in SIP stack when we receive a 180/200 OK/BYE message from the remote side. This is because of "maddr" coming in CONTACT header in 180/200 OK/BYE messages.
