[Asterisk-Users] Polycom Echo

[Wiley E. Siler]

I have Polycoms and I sometimes have echo.  However, it is always on an
incoming call and always a matter of echo training.

Have you already worked through all the settings for ech in *?
Are you adjusting rx and tx gains?  
Do you have echo cancellation set to high?

What are the rest of the parameters for your particular problem?

Subject: [Asterisk-Users] Polycom Echo

Lately I have been experiencing a lot of echo from my Polycom phones.
Only I hear the echo and it's not on every call.  I've researched it via
google and the forums and every echo problem usually relates when it's
using a Zap card and not an IAX provider.

Can anyone give me some advice or where to look to help solve this echo
problem?  This never occurs on any of our other phones, Ciscos,
Grandstreams, Sipuras, etc.. Only on the polycoms.

Any help would be greatly appreciated.

Thanks in advance.
