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.

Does it happen randomly, or have you seen any indication of a pattern of behavior? Perhaps if you could post your zaptel/zapata configs, and maybe some CLI output when this happens, it would be easier for us to help you out. We've got a client who's been using an A200 with 24 ports over the past 7 months, without any problems like what you mentioned. Cheers, Flynn

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. - Mike
