Re: [asterisk-users] Echo on hard SIP devices...
For the first time on Wednesday, I noticed SIP-SIP echo...very weird. Normally, I run G729 between all my Grandstream GXP2000 phones, but I tried X-Lite to call one of my Grandstream. This of course switched my codec over to GSM. I had headphones on the PC and the mic muted. When I spoke in the Grandstream, I could hear a distinct echo. This even occurred with the Grandstream in another room thinking that the microphone wasn't truly muted. I do know that the audio stream should not be echoing, and it never has with G729, but the GSM codec must have something in it. I do not allow my phones to re-invite, so Asterisk was in the stream, but so X-Lite could be the issue. I was thinking of trying with SJPhone... just haven't had time yet. > We have an installation with around 50 sip phones but only 5 of > those are hardware.

I still think the problem may be with the switch but I just want to check if anyone has had an experience like this before. Who is hearing the echo ? Your users or the party at the far end ?

[asterisk-users] Echo on hard SIP devices...
We have an installation with around 50 sip phones but only 5 of those are hardware. There are three Grandstream phones, one Snom and one PAP2T. We are running Asterisk 1.2.8 with an E1 (R2). Only the hard phones are having problems which are either echo or distortion. The softphones all work fine and no one is reporting any problems. They are using 3Com switches which are fairly new. I have really tried all the settings I can think of and it seems impossible that all 5 hard phones are defective. Obviously the customer is irritated because the hard phones belong to the director and the receptionist and they notice the problem all day. I still think the problem may be with the switch but I just want to check if anyone has had an experience like this before. -- Carlos Chavez Director de Tecnología Telecomunicaciones Abiertas de México S.A. de C.V.
