Is it possible to disable hardware echo cancel on one of the 4 ports of a Sangoma A104? I have that port connected to an Adtran 614 used for faxing. Faxing is not working well.
It would depend on how you have dahdi configured, but on my system running a Sangoma B600 card w/ hwec I have these lines in /etc/dahdi/system.conf:
Sangoma AFT-600 [slot:4 bus:3 span:1]
IIRC you set the echocanceller=none to disable, but my quick googlefu can’t confirm that.
please refer this:
you have need to disable that port in wanpipeX.con file
