We're not using any zaptel hardware though. I didn't think the echo cancellers would be doing anything? We're digital and sip from end to end. Do I need to disable echo cancellation in some way?<div><span class="gmail_quote">

Gary,<br><br>I would check echo cancelling parameters first. I've seen this to happen<br>with one of the zaptel echo cancellers. Try to change the default echo<br>algorithm in zconfig.h, and recompile and install new zaptel. Also
<br>zapata.conf echo parameters may need to be changed either way.<br><br>Andrei<br><br>Gary Richardson wrote:<br>> Hey All,<br>><br>> I've been experiencing a problem for a bit. During a call to the PSTN,<br>> audio will cut out for 2-5 seconds. It's completely random and may or
