I do not have a hardphone to play around with, but the echo is there both with built-in audio card (SigmaTel) and Bluetooth headset. There are no mixer settings than I can adjust as well. I'll try disabling AGC and/or lowering mike sensitivity.

According to the excellent Cisco paper "Echo Analysis for Voice over IP", which the Wiki links to at:


http://www.cisco.com/en/US/tech/tk652/tk701/technologies_white_paper09186a00800d6b68.shtml


"Headsets are particularly notorious for poor echo performance.". This is due to lack of acoustic isolation. Perhaps you could test using headphones and a mic.


After reading the above paper, I was able to tune my setup and make a significant improvement. Given the high number of questions about echo on the list, it would almost be worth including the link to it as a file, "README.echo" in the source.
