[Asterisk-Users] Digital Line Distortion

[Klaus-Peter Junghanns]

Hi Adam,

what is your echocancel setting in zapata.conf for the PRI spans?
I once noticed this distorted sound by using echocancel=256 (using
mec2.h for echo cancelation).
How about echocancelwhenbridged and echotraining?

best regards

Klaus
