[SR-Users] no debug trace of incoming request

[Ben Kaufman]

Was the SIP message on a TCP port where another process was listening?



I think that a SIP message sent to any TCP port should show up in sngrep, so if you have a webserver, etc. listening then the full packet flow might look like this:





remote_host:12345                 web_server:80

              === TCP SYN         ===>

             <=== TCP SYN/ACK     ===

              === TCP ACK         ===>

              === SIP INVITE      ===> **SHOWS in sngrep**

             <=== TCP ACK         ===

             <=== 400 Bad Request ===  **NOT in sngrep**
