EMail notification upon VM box full

[rossiv]

I use PIAF at home and I unknowingly had our VM box where general calls go to fill up back at the beginning of November. I didn't get any emails or anything. And I hang up before I try to leave a message anyway so I never heard the recording. I have changed the limit now in vm_general.inc (IIRC) to 9999. Back to the point - Is there a way to have an email sent to a specific address when a mailbox reaches capacity?

Thanks!
