Hello Sir,
I am new in asterisk chan dongle project. Recently I installed asterisk and 
chan dongle in ubuntu and also installed g729 codec with asterisk. And I used 
iax.conf to connect it with another asterisk server as a peer. And used that 
asterisk user server as a sip gateway. I wished to pass sip calls through the 
asterisk server to the dongle. When i tried to make call I got response both 
the asterisk user and peer. But in the user asterisk I got an error that is 
saying "Fail to retransmit" which making the call fail. I don't know how to 
solve the issue. Please help me to solve this.

Thanks in advance
