[Spce-user] Conference Calls

Wed Sep 10 09:53:02 EDT 2014

Looks like PCMU is being used.
I should add that conferencing is the only feature not working.  Regular calls and voicemail forwards are ok.  When I call the conference from a registered subscriber it works as well, but when I call from my cell phone for instance I get silence.

Hi,
please check if the RTP stream actually reaches the external participant.
Also check if the external user and the conference are sending RTP with the same codec (should be PCMU).

Trying to forward a number to a conference room, I am getting one way audio. When dialing in externally, the external user gets no audio.

This sipwise server is public facing (no nat)

I have attached a ngrep-sip trace for one of the calls and pasted the kamailio-proxy.log below, if anyone can shed some light please let me know..

Thanks
