[Serusers] rtpproxy and one to many aliases. - sr-users

5 Oct 2004


      Hi All,
Running ser (cvs branch 0_8_14) with rtpproxy (cvs HEAD), all works very 
well. One to one aliases work fine.
Example;
122 alias points at 136
Call completes perfect
124 alias points at 133 and 150
Both phones ring, but when one is answered no audio either way.
Below is ngrep output of a call made from 8667 to the alias '124' that 
maps to 133 and 150.
When 133 returns OK with SDP it sends m=audio 10000 RTP/AVP 8 101
ser sends the Ok onto the caller (8667) with m=audio 36574 RTP/AVP 8 101.
The callers UA (8667) then trys to establish rtp with rtpproxy at 
10.0.0.5 on port 36554, put that port is closed and the host kicks back 
a ICMP destination un-reachable.
When doing the same call with a one to one alias mapping the behavior is 
similar, except of course rtp gets sent to rtpproxy successfully.
Any ideas?
