I’m new to Echo Cancellation and I was wondering how it is handled/works on pure VoIP networks using Asterisk?<br>
</blockquote></div>
there is no echo problems on pure VoIP networks.<br>
<br>
echo is a common problem when you have changes from analog to digital.<br>
<br>
The only echo problem you will have is when you call another network who has analog circuits with wrong configuration or poor hardware. But you can't solve it.<br>
<br>
Best regards.<span class="yiv5150191683HOEnZb"><font color="#888888"><br>
