I have installed
Asterisk (Ver. 11.9.0)
FreePBX 2.11.0.23
Hardware: Digium Tdm410 with 2 FXO.
At the graphical menu in DAHDi is activated but if I don’t modify the file /etc/dahdi/system.conf adding echocanceller=oslec,1-2 dont work.
When I modify the file and restart asterisk works like a champ but then in some minutes the echo comes back and the line of echo canceller disappear.
I already search for disable the dahdi helper in module admin and I dint found the helper just the entry module.
All echo cancelers have limits. You may be exceeding those limits. You likely have issues at a provider level, internal wiring or potentially the physical port. It sounds like somewhere a capacitance is building up. Typical things like fxotune will not work if the hybrid is not consistent
Tnx for the fast response, i dint explain correctly (sorry about my terrible English), the problem is the echo canceling just disappear at the configuration file. And I need to put back for set work again, I dont know if the order maters or what im doing wrong my files lok like this.
I added manualy the “echocanceller=oslec,1-2” boot then the file modifies and appears only like this.
fxsks=1,2
loadzone=us
defaultzone=us
And I lost the echo canceling.
At the header sets don’t modify the file but is the only way I can activate the echo cancelling (at the administration page general settings is set on) but doesn’t appear on at DAHDi page.
