Since I killed and restarted Asterisk, I've been getting this message repeatedly:
"Aug 30 23:52:50 fax php: /var/lib/asterisk/agi-bin/libs_a2billing/Class.RateEngine.php[722]: Undefined variable: agi"

I did not do any other operation other than restart and reload Asterisk.
I took no specific A2billing related action.

I'm worried that something has gotten messed up in the billing.

I think you're right to be worried. I hope you're keeping an eye on the CDRs after making a call to ensure folks are being billed correctly.

I've not seen this particular problem before, but you're not alone. Are you running the same distro as rrisco? What version of Asterisk are you running?

The code around where the fault occurs is responsible for writing the CDRs and deducting the cost from the card. I can't see how execution could get that far without the AGI global being defined. A complete guess: if you're running certain versions of Asterisk 1.4, this could possibly be caused by using DeadAGI not AGI. Probably not, but I'm at a loss as to any other explanation.

I'm running Trixbox version 2.0.0. Is there any additional information I could provide which would help in debugging this problem?

Your Asterisk version. I'm not familiar enough with TrixBox to know if this dictates your Asterisk version.

Did you try swapping AGI for DeadAGI (or even vice-versa) temporarily?

No, I didn't try switching. How do I do so?

If TrixBox uses default Asterisk conventions you need to edit /etc/asterisk/extensions.conf (after making a backup). Replace instances of 'DeadAGI(' with 'AGI('. Save. From the Asterisk console 'extensions reload'. Then retest.

I only just noticed this part. If you had to kill Asterisk I guess it's possible this might have left some pidfile, lockfile or other session information lying around. I know it's anathema on Linux, but does a reboot make any difference? It's an easy way to clear out /tmp and /var/run.

You could very well be right. We're going to do a reboot later when traffic slows down and see if that doesn't help.

I should make it clear that my previous advice about checking DeadAGI/AGI is based on the assumption that at some point Asterisk was upgraded on this machine.
Are you 100% sure that nothing was changed/upgraded on this system since the last time Asterisk was restarted? If so then don't bother swapping DeadAGI/AGI, as it evidently worked for you previously.

BTW we still don't know your Asterisk version, or whether your CDRs are being generated correctly. Please advise.

I thought I had posted the Asterisk version, sorry. It's version 1.2.13

hi yitzhakbg
did you solve this problem?

Thanks very much for your interest.
I keep getting messages like these in the log. I'd love to fix it.

These look as though your a2billing.conf file is corrupt in some way.
These are troubling. I guess they could be caused by the AMI credentials in a2billing.conf not matching those in manager.conf. What does the Asterisk console say when you modify a SIP friend and click Reload?
