X100Ps connected to analog lines. The system works well except for
the occasional echo problem. I have all the echo parameters
configured, removed all the extra incoming analog lines except to the

Zaptel 1.2.20 echo cancelling problem
...echo problems.
It seems to work OK if I use a quieter-than-normal speaking voice, but
at a sufficient sound level, the echo "breaks through" and then never
goes away.
The problem goes away if I revert to 1.2.19.
Hardware in question: Digium TE110P, Adtran TA750 channel bank, Adtran
1175407L2 FXO card. The phone was on a TDM400P FXS port.
Is there something else I need to tweak in 1.2.20?
