Hi,<br> We have a PRI connection & when its was on test networks we had echo problems withoutside line. <br><br>So I bought a TE212P card resolve the echo problem. Which did to an extent. Its using asterisk 1.2.18 & RHEL4-Update 4.<br><br><br>But now when we are live, there is a terrible echo between 2 SIP calls. If I call the same extension from outside the voice is clear.<br><br>I am not sure whats the problem. Also there's slight echo when calling Digium support.<br><br>Totally lost Digium says we need to remove the echo module to resolve SIP echo problems. Then ? the heck we pay for...<br><br>Has anyone come through this issue.<br><br>--<br>Deepak<br><p>
