<div dir="ltr"><font face="Tahoma" color="#000000">Hello...<br>
We're attempting to track down an intermittent echo issue. Our setup is<br>
<phone>sip<asterisk>sip<tnt>pri to carriers. We have less than 2 ms latency on the networks (FTTx), totally SIP w/ G711u. The party hearing the echo is the subscriber using sip. The PSTN users does not hear the echo.
</font></div>
<div dir="ltr"><font face="Tahoma" color="#000000"></font> </div>
<div dir="ltr"><font face="Tahoma" color="#000000">We should be note that there is zero echo when calling sip to sip with or without reinvites enabled.</font></div>
<p><font face="Tahoma" color="#000000"><br>
We have several different phones; linksys, polycom, & grandstream (both atas and phones). It's difficult to reproduce the problem regularly so isolation is an issue. </p>
