Yeah I noticed the help option just minutes after I posted my first message.
I now have audio working howver the app crashes every few minutes.
I ran it from the console and got:
~DspOutRtp::MaxBufferSize: 16384
SipClient: STUN request
SipClient: STUN request
res_search: NO result !
res_search: NO result !
MessageSocket::setHostname(): gethostbyname() failed: No such file or directory
as the last couple lines before it crashed.
