[Asterisk-Users] echocancellation in modem.conf

[Edin Kozo]

I have a ISDN BRI card with hisax module (w6692) and there is a lot of echo 
when I make calls to outside. Between the sip softphones the echo doesn't 
exist, but when I call to outside through the ISDN the echo exist.

Is there any sense to put echocancellation in modem.conf ?
