I'm experience echo on outgoing calls: Snom 200 ----> Asterisk ----> T100P ----> PRI ----> called party
I am getting echo on the Snom 200 phone. The called party does not
hear the echo.
Rule of thumb (i.e. a good starting point): if you hear the echo it is coming from somewhere else, your equipment mearly makes it noticable. In this case the echo is probably caused by an analog conversion at the remote party. This is quite common but for calls with a very short latency in the call path this is experienced as a reverb and not an echo.
Reverb might be a good description.
If this is the case--that my CLEC is the source of the echo/reverb when they do a digital to analog conversion, is there anything I can do about it, except try to cancel the echo? Can I ask them to change any settings? They have a 5E switch. My collo is right next door--I just cross connect to get my PRI.
The echo I am experiencing is on local calls.
My * server is a dual-processor XEON (2.4 Ghz) Supermicro server. Its relatively fast. I will reduce the number of taps, and I was also thinking of decreasing the sample size on the phone from 20ms to 10ms.
It seems that echo is not related to processor speed but type of hardware inside. Somebody post, one month ago, to have echo with a Supermicro server then moved to a slower machine, a DL380, and the echo disappear.

thanks a lot!
