[Asterisk-Users] Echo canceller on TE406 & Asterisk

[Boris Bakchiev]

Hi Kevin,

Thanks for your reply.
That probably what it was. :)
Could echo cancellation on PBX conflict with VPM module and create the
"warping babble" sound that my users are reporting?

Do echocancelwhenbridged and echotraining do anything when VPM module is
used? Should I be using them?

Regards
