It goes like this:
A call comes in via chan_zap. It will ring until we pick it up from a sip phone. At that moment the call will be disconnected.
The event log was off, and the message log was unremarkable.
I turned on the event log and added debugging info to the message log.
I just upgraded from 1.4.21 to 22.214.171.124 today, and upgraded zaptel. Libpri and addons are still at 1.4.7, and no updates are available for the sangoma driver.
Ideally someone reading this will know what the problem is, and point me to a solution, but in case that doesn’t happen: what else can I do to put myself in a position to find a solution to exorcise this demon?
Ideally, I’d like to put myself in a position to file a bug report the next time this happens, but from experience I know that if there is no crash / dump I will have little support on the bug tracker.
So what’s the next best thing?
P.S. I’ve had an asterisk server since 1.0.X at this location, I’ve gone through 3-4 motherboards in that time, went from TDM400P to Sangoma hardware, 64-bit to 32-bit linux, reinstalled gentoo perhaps 7 times, and swapped all kinds of other hardware that comprises the platform. None of those upgrades, downgrade, or changes have allowed me to achieve my modest goal: 30 days of uptime with no issues like these (and there are others).
