My office has been running Asterisk 1.0.8 and a TDM04B for a few months now without too much trouble. After a while we discovered that after a certain period (about a month), asterisk stopped acknowledging inbound calls. Since I was out of the office the first time it happened, another admin rebooted the whole box which solved the problem. The second time it happened I discovered that just restarting gracefully solved the problem, so I put that into my cron and forgot about it. (I know, it's not "right", but debugging something that happens unpredictably once a month could go on for way too long to be acceptable..)

Check the revision of the TDM card. If rev E/F, call digium support to
get it replaced. Known problem with early versions of the card.
The rev is labelled on the itty bitty xilinx chip and not under the modules, right? Dang, rev F. Okiedoke, off to digium I go. Thanks!

we also experienced this with asterisk 1.0.9 and rev H of the tdm with 4 fxo modules

we were restarting asterisk every night via cron and this still happened

in our case, 3 out of 4 fxo modules (2,3,4) crapped out and stopped ack'ing incoming
calls (outgoing calls were fine)

it took a reboot of the server to get the card operational again and answering calls

Your problem might be with the rev of the card, but I believe it is in the zaptel software
for the newer versions of asterisk.

in the past, It was the zaptel software that would not restart the tdm card (400b) on a soft reboot, on some cards (rev H). Needed to hard boot to get things working, until the code
was changed in wctdm.c specific for rev H.

I have swapped out the tdm and modules with albeit same rev parts, but newer units to see
if the issue is the same.

I still think it is in the software as we did not have this issue with earlier versions (1.02) of *

Please post your resolution if any.
