[Asterisk-Users] Echo heard by person receiving call

[Klaus-Peter Junghanns]

hi derek,

you might want to play with rxgain and txgain. it seems
that you experience an echo that is caused by the mic of your
phone picking up the audio from the speaker of your phone.
try adjusting the rxgain.

regards
