Hello and thanks in advance for the support.
I installed an A200 Sangoma Card with 4 FXO ports. in Asterisk 1.4 running on Debian and connected to Telmex lines in Mexico.
All works perfectly, sound quality is excellent, it receives and sends calls and detects the end of calls perfectly.
But…
I have trouble with Answer Detection. When I dial a call, as soon as I hear the first ring Asterisk takes the call as connected, we tried using polarity switch detection but it connects only when the voice is loud.
we already tried all the signalling types and doesnt work.
I am pasting my zapata.conf to see if anyone can help me with this.
