I tried to connect two Analog phones and a SJPhone(Softphone) to Asterisk server. Here all three phones are registering with the server properly. And i gave the option as [b]directmedia=no[/b] that means all RTP packets should pass through Asterisk server. Here two analog phones are in one network and SJphone is in different network. I am connecting these two networks to the Asterisk server. When i give the option [b]directmedia=yes[/b] i can hear the voice clearly, between both sides from SJPhone to analog phone and between analog phones also. But when i give the option [b]directmedia=no[/b] the voice is getting noise and fluctuated. Can any one tell me what was the problem.
