[OpenSIPS-Users] No Voice Comm in Conference call

[Arjun Shankar K S]

Hi All, 

Greetings to everyone !!! 

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. 

Now I have installed RTP Proxy in a direct public IP. Normal calls between 2 Client is working great !! 

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. 

I could not find much support regarding this issue. Any support is sincerely appreciated. 

In my opensips.cfg, I have made the following config changes for RTP in different host, 

------Nat Params------------- 
modparam("usrloc","nat_bflag", 6) 
modparam("nathelper","rtpproxy_sock", "udp:rtp_proxy_publicIP:7890") 
modparam("nathelper","natping_interval", 30) 
modparam("nathelper","ping_nated_only", 0) 
modparam("nathelper","sipping_bflag", 7) 
modparam("nathelper","sipping_from", "sip:pinger at PROXY_IP") 
modparam("registrar","received_avp", "$avp(i:42)") 
modparam("nathelper","received_avp", "$avp(i:42)") 

I am running my RTP Proxy using the following command, 

./rtpproxy -l rtp_proxy_publicIP -s udp:*:7890 -F 


Thanks, 
Arjun
