Dear list
I am quite new to Kamailio and i have been able to solve some NAT Traversal issues with symmetric SIP+RTP putting kamailio+rtpproxy behind NAT, i am also load balancing some asterisk boxes for transcoding and some other services like voicemail. Also i am using SIPp for load testing
Now the question is that, while everything is working great with NAT (even when i am using SIPp for testing with low load) when i am about to test it with more than 150 calls or something i am starting to get the following error:
/kamailio[34549]: ERROR: rtpproxy [rtpproxy.c:2735]: force_rtp_proxy(): incorrect port 0 in reply from rtp proxy/
A guess, but each call takes 4 file descriptors, so you might be running into the normal os limit of 1024 open files per process. Recent rtpproxy versions have the -L option to increase the limit. It should be 4 times the number of concurrent calls you expect to handle.
Again, just a guess.
