Hello all,

Thank you for your time to see this message.

I have configured elastix only with a sip provider, no cards at all. I have other box doing the same, but only with asterisk, and same sip provider and has no echo.

What can cause echo on a sip trunk? I am using snom m3 and Linksys SPA 941 and I have echo on both.

Not all the calls have echo, but most of them have.

Thank you for your support
Filipe

Have you tried turning down the handset volume? The SPA9XX mic can be pretty sensitive.

What about if you dial *43 and use the Echo Test, can you hear the additional echo?
