<tt>Hello,<br>
<br>
Lack of audio typically means you are facing issues related to
network topology - either net bridging, either NAT.<br>
If you have NAT, you need to use RTPproxy - to see if RTPP is
properly inserted, check the SIP signaling to see if the "c" line
in the SDP is changed to the address of the RTPP.<br>
<br>
Regards,<br>
