<tt>Hi Arjun,<br>
<br>
If you have no audio at all for the call to Conf Server, you need
to check the signaling, particularity speaking the SDP part to be
sure you inserted RTPProxy correctly between UAC and Conf Server.<br>
<br>
So, make a SIP capture for the call to Conf and check if the IPs
in SDP are correct.<br>
<br>
Regards,<br>

All,<br>
<br>
Greetings to everyone !!!<br>
<br>
I have set up opensips and RTP Proxy in two different hosts since
I have opensips in a Natted environment where RTP Proxy refused to
budge.<br>
<br>
Now I have installed RTP Proxy in a direct public IP. Normal calls
between 2 Client is working great !!<br>
<br>
During conference call, the calls get connected but there is no
voice communication between any of them and soon the client who
was connected last, gets disconnected.<br>
<br>
I could not find much support regarding this issue. Any support is
sincerely appreciated.<br>
<br>
In my opensips.cfg, I have made the following config changes for
RTP in different host,<br>
