[Asterisk] Card stops responding, can't restart Zaptel

Hello

The hardware is an OpenVox PCI card with a single FXO module (pciconf -vl says: "wcfxs0@pci2:11:0: class=0x078000 card=0x0003b100 chip=0x0001e159 rev=0x00 hdr=0x00").

This PC with FreeBSD 6.3 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.

At this point, the host is running again, but I can't restart the card using the standard script /usr/local/etc/rc.d/zaptel restart:

[code:1]
zaptelkldunload: can't unload file: Device busy
zaptelkldload: can't load /usr/local/lib/zaptel/zaptel.ko: File exists

Has someone seen this before? Any idea what happened, and what to do to reduce the probability 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. Also, is there a way to monitor the card to keep an eye on it?

Thanks for any hint.

It looks like the card keep busy, should be a s/w issue, please check your indications.conf and busydetect busytone etc.

Correction : I did edit indications.conf so it uses settings for France:

[code:1]
[general]
;country=us ; default location
country=fr
[/code:1]

So the cause for what happened is not due to wrong settings.

Thanks for the help. Since I don't have the settings for France, I left the default choices. Would you have the settings for France by any chance?

But if the settings aren't right, why would the card remain off-hook after three months of successful operation?

Also, why couldn't I stop/start the card, and had to reboot the host?

Is there a way to monitor the card to make sure it's working OK, and doesn't remain off-hook after a call?

Thank you.

Jun 18 12:27:47 freebsd kernel: VoiceDAA did not bring up ISO link properly!

This means that the FXO module are not working correctly, If it continue occur, should be a h/w failure.

OK, I'll keep an eye on it, and order a new module if hardware looks faulty. Thank you.

Hello again

I had the same type of problem again: On a FreeBSD 6.3 host, Asterisk would stop answering calls through the OpenVox FXO card, and FreeBSD failed restarting Asterisk, or even unloading the Zaptel driver:

Do you think it's a hardware issue? Besides buying a new one, are there things I could try before rebooting?

Thank you.
