Hi,

I am using SIP phone (Polycom 300). Echo is present even if other party has sound hardware disconnected.

It is definetely network and/or PC setup issue, but is not related to audio setup. I will check stereo mix, however.

To repeat the question from Matt Riddell:

We have found the most common cause of a strong echo to be that the sound
card is set to record the outgoing earphone signal.

If you post inline it is much easier to see what your answers were to
different questions or if you have missed one.
