Or any clients for that matter.
I spent what would’ve been hours of joy playing and playing with the fun toys of Asterisk, but, I found myself trouble shooting intermittent problems with clients behind a NAT. What threw me off was that one softphone (Bria) would send/receive RTP every, single, time. But others, not so much.
What was it?
Turned out that I had the range “10000-10200″ in my rtp.conf.
But in my firewall? I had “10100-10200″.
It was a typo in my rtp.conf. Dammnit. So hopefully if you are googling for intermittent RTP problems with natted clients, you find this and you double check it. Man was that frustrating!!!
