Steve I understand your theory. We have Poycom 501 phones. Prior upgrading to PRI
we were till date using 4 analog lines connected with TDM card from digium & no
echo for pure SIP to SIP lines.
Now I have TE212P which had onboard echo cancellor.
I am trying make myself clear before I blame on any network. B'cos for sure we have a spegati of networks & no QoS. Also the intresting thing is if I call from one extension to other dialing the main line & then extension the call is crystal clear. but when dialing a direct extension its a hell of echo.
Make SURE you have the handset plugged into the handset port of the
phone, not the headset port of the phone.
