8.4(7) 9.0(4.7) 9.1(5.1)

Description (partial)

Symptom:
A SIP receiver endpoint intermittently fails to parse a SIP message (e.g. INVITE) because of extra characters in the beginning of message, causing call failures
OR
A SIP receiver endpoint receives Malformed SIP message.

Conditions:
- SIP inspection is enabled on ASA.
- A SIP message sent by the sender contains a SIP payload. For example, XML dialog-info in NOTIFY packet. This message doesn't have to be the same message that was rejected by receiver. Any message sent previously in same connection can trigger the problem.
- That SIP payload (the XML portion, and not the message itself), contains a SIP URI followed by maddr parameter. For example, sip:12345@X.X.X.X:5060;maddr=X.X.X.X.
- The ASA is to rewrite the SIP URI (host and maddr both) using a translation rule on it.
