Yes, that's correct. Sorry, I didn't think about the fact that I hadn't explained that when I tried your suggestion. Setting both rtp-ip and ext-rtp-ip explicitly solves the problem. That part of the mystery is solved... THANK YOU. Interestingly though, the previous settings for these values were: param name="rtp-ip" value="$${bind_server_ip}"/ param name="ext-rtp-ip" value="$${external_rtp_ip}"/ (Nabble won't let me put the syntax markers '<' and '>' in) And these worked just fine before. Any idea why they might have suddenly stopped working? Can you use host:host.server.com to do a DNS lookup like you can for the other SIP profiles?
