Hi Maxim,
The Nortel Client does not support silence suppression. You can take a look
at the ngrep traces I sent and you will see that both UAs are transmitting
audio to the RTPProxy, but it does not relay it to their destinations.
Regards,
Ricardo

Try to disable VAD (aka silence surpression or
compression) in Nortel if
it supports that, it might help.
