[asterisk-users] [FreeBSD 6.3] Zaptel stops responding

[Vincent]

Hello

	This PC had been running a Ports-compiled Asterisk 1.4.16.x
succesfully for almost three months, but this morning, although
Asterisk itself seemed fined, the Zaptel interface stopped taking
calls.

Stopping/restarting Zaptel using /usr/local/etc/rc.d/zaptel stop-start
didn't let things recover.

Since I didn't know better, I had to reboot the host to get things
working. I used this opportunity to upgrade to Asterisk 1.4.20.1_1 and
Zaptel 1.4.6_5.

The hardware is an OpenVox PCI card with a single FXO module. I know,
it's not a $200 Sangoma, but then, we only get a few calls/day.

Has someone seen this before? Any idea what happened, and what to do
to recuce the probabilty that it happens again? For instance, since
it's a low-use host, (I don't mind running a CRON job to stop/start
the driver a couple of times a day to keep things running.

Thanks for any hint.
