[asterisk-users] wrond DTMF detection on Zap channel

[nik600]

I'm using Zap, not chan_local

i've tried to record the call and have seen that the audio DTMF toned
received is very poor, i've tried to put relaxdtmf=yes in zapata.conf
and increare rxgain and txgain from 0 to 5 but it doesn't seems to be
much better.

Is there something else to do?

Thanks
