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. -- MBM
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?

I have the same problem. I've got 35 IP500s. I get the echo but can't trace the blame to one thing. It only does it part of the time, and it can be on a SIP<->SIP call, IAX<->SIP call, or PR<->SIP call. Jody N.

Guys. I have about 20 Polycom 301, some 501 and some 600 and I really like the phones, but I have a question and maybe somebody else has seen this. Seems sometimes when people talk a bit loud, Polycom phones have a tiny bit of echo, can this be controled with some kind of gain or AGC or something on the xml files? Has anybody seen this type of echo?
Hello, We just experienced a problem that we though might be useful to anyone using Polycom phones. We are installing a new system at one of our remote offices and were experienced a ton of echo on our side while the remote side was on speakerphone. It turns out that the desk surface was causing the echo - when the phone was lifted off the desk, the echo disappeared. We also were able to put a mousepad under the phone to eliminate the echo as well. Since the microphone is on the bottom of the phone, there must be some kind of sound reflection going on. Just a heads up - this is the first time we've seen this happen. Kevin
