No audio issue - sr-users

7 Apr 2014

Hi,

I am at the point where connection is established and no apparent errors are reported.

However audio is not output.

The rtp traffic seems to be transfering between the points as conclueded because Asterisk
debug log shows 

Sent RTP packet to      10.1.xxx.xxx:41143 (via ICE) (type 08, seq 021868, ts 221760, len
4294967284)
Got  RTP packet from    10.1.xxx.xxx:41143 (type 08, seq 001383, ts 1917269534, len

And the browser machine on the other endpoint on a tcpdump does shows traffic on the port
(41143)

What could be causing there to be no audio?
