[SR-Users] rtpproxy_manage fails to rewrite SDP

[Igor Potjevlesch]

Hello,

I done the manipulation.
I still have some errors "incorrect port 0 in reply from rtp proxy" with a
moderate flow of calls.

I don't really know where to look at for solve this issue.

Any other ideas? Thank you.

Regards,

Igor.

Hello Richard,

Thank you for your suggestion.
I set "ulimit -n 60000" on the server. I will restart rtpproxy tonight and
see if there are new errors tomorrow.

Regards,

Igor.

It could be that the maximum number of file descriptors allowed for the
process has been reached. You can try executing "ulimit -n 60000" before
starting the RTP proxy daemon. Just a guess. In any case, the daemon should
log an error if it fails to open or allocate a port. If it doesn't, you can
try hooking into the running process with strace to see what's going on.

HTH
cheers
