[SR-Users] Kamailio/RTPProxy incorrect port 0

[Daniel-Constantin Mierla]

Hello,

typical reasons for this error are:

- the session is not found by rtpproxy (if it was an update command)
- rtpproxy run out of file descriptors (check the limits of your system
regarding opened files per process)
- some internal error of rtpproxy (see if there are errors in syslog
from rtpproxy, you can also run it in debug mode with -D DBUG command
line parameters)

Cheers,
Daniel
