Hello list...
I've installed SER 0.9.0 and mediaproxy 1.2.1 and dowloaded the getting
started scripts (issue 04a) from onsip.org.
Setup everything as instructed, added a couple of users to the database and
tried to setup a call between one public and one NATed UA.
Both phones register properly and signalling seems to be working fine, I
ring each device from the other, problem is there is no sound.
So I checked the mediaproxy sessions... and it looks like this
Caller Via Called Status
Duration Codec Type Traffic
----------------------------------------------------------------------------
----------------------------------
82.182.194.x:5004 - 212.247.91.x:35014 - 82.182.194.x:49160 inactive
0'07" Unknown Audio 0/0/0
Total traffic: 0bps/0bps/0bps (in1/in2/out)
Session count: 1
I dont really understand the output but I think "inactive" as well as
"Unknown Audio" is not a good sign.
How ever, I then used Ngrep to see if there are some rtp traffic going on
and sure enough, there is traffic comming in from both UAs but no traffic is
leaving the proxy. Strange!
Anyone with some bright idea on why mediaproxy is not relaying the sound?
