Description (partial)

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.
