I recently dealt with echo issues and the polycom phones, specifically
when using headsets. I used the following settings in my sip.cfg to fix
the problem.
voice.aec.hs.enable="1"
voice.aec.hd.enable="1"
voice.aec.hf.enable="1"
voice.aes.hs.enable="1"
voice.aes.hd.enable="1"
voice.aes.hf.enable="1"
Also I using sip version 1.6.3.0067 and bootrom 3.1.2

What We are hearing here is that our local users say when they raise their
voice, sometimes they hear themselves back.. So I guess.. If We have RX and
TX setting on the polycoms.. Lowering the TX setting might help.. For those
screaming users :)
