Severity: 3-Major


When a SIP message is loaded, the SDP is parsed. If modified or replaced, the system does not reparse the modified payload.


Changes to the SDP are ignored when creating media pinhole flows


This occurs internally while processing SDP in a SIP message.



Fix Information

The SDP payload is now reparsed if modified or replaced.
