For our internal fax machines, I'm checking if the faxes are going to
branch offices. If they are, I want to capture and email them to the
branches. I've set up extension 8447 to test this.
A fax machines is connected via an SPA 2102 on 173. Any calls from 173
are sent to:
[outbound-fax]
exten => 8447,1,Answer()
exten => 8447,n,GoSub(Capture-Fax,s,1)
exten =>_NXXNXXXXXX,1,Answer()
exten =>_NXXNXXXXXX,n,GoSub(DialOut-PSTN,s,1(1${EXTEN}))
exten =>_1NXXNXXXXXX,1,Answer()
exten =>_1NXXNXXXXXX,n,GoSub(DialOut-PSTN,s,1(${EXTEN}))
exten =>_91NXXNXXXXXX,1,Answer()
exten =>_91NXXNXXXXXX,n,GoSub(DialOut-PSTN,s,1(${EXTEN:1}))
Actual outbound faxes work correctly. That is, a call from 173 to an
outside fax machine works.
The test faxes go to:
[Capture-Fax]
exten =>
s,1,Set(FAXFILE=/var/spool/asterisk/fax/${STRFTIME(${EPOCH},,%Y%m%d)}_${STRFTIME(${EPOCH},,%H%M)})
exten => s,n,ReceiveFAX(${FAXFILE}.tif) ;; 1.6 use ReceiveFAX
exten => s,n,Hangup()
When the test fax gets to ReceiveFax() asterisk restarts. Any calls at
the time are lost.

I've set debug and verbose to 20, but no further info.
What am I missing? Anybody have something like this working this working?

On Exten 8447, why are you using a GoSub instead of a simple Goto? (Shouldn't pose a problem, just curious) 2. I wouldn't recommend the use of date-time only to form the filename of the received fax. This was the key issue that was killing asterisk in my case, when I switched to date-time + uniqueid for example, everything went fine. That's because it looks like RxFax() or in this case ReceiveFax() doesn't play well with duplicate (open) filenames, which I don't know if they occur in your case. It definitely can happen if you have programmed it and have the capacity to receive simultaneous faxes at a time. After the change my machine is rock stable, receiving and sending hundreds of faxes a day with no restarts. Hope this helps. Cheers, -- Ing. Miguel Molina Grupo de Tecnolog?a Millenium Phone Center
