You were right and I was wrong.
New sound card fixed all problems. Still can not beleive that problem was
caused by audio hardware, but there we are.
Thanks to all who replied.

You don't get 'echo' on the network, you'd only get true echo
connecting to analogue PSTN lines so as Matt pointed out it will sound
set-up/card related. What you could be getting is feedback or sidetone
- so check for things like mic boost and turn that off and it may even
be worth trying another sound card - we've had instances where the
onboard sound of a motherboard was really crap (with 'echo' like
problems) and it was resolved by disabling and putting in the Creative
card...

Hi,
I am using SIP phone (Polycom 300). Echo is present even if other party

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.
