Hi all,
I have a Sangoma A200 card with hardware echo cancellation. The card has
12 ports (10 of which are active; All FXO). Twice on this particular
card I've seen all ports simply stop receiving incoming calls. There is
no other indication of this, however. I am able to place outgoing calls
just fine, and call other extensions without issue. When someone calls
in, the line just rings and rings, with no indication that the card even
sees the calls. I'm not even sure where to begin looking into this.
Could anyone give me some pointers as to what I might need to be looking
for?
I'll be giving Sangoma tech support a call, but if anyone has any
debugging pointers, they would be much appreciated.
Alex,
Does it work if you disable the hardware echo cancellation?
I had an A20002D that started to fail after a month or too of normal
operation - it would answer PSTN calls, but the callers couldn't hear
me, although I heard them. Disabling the HWEC cancellation made things
work, but the echo was intolerable.
My vendor (Telephonyware) replaced the card (after I tried it in another
computer, running another kernel, and testing the original server with a
spare A20002D, and cleaning the FXO and HWEC module sockets), and the
replacement has worked great since then.
