This describes a context that is a wrapper for a generic call file format. The idea is to do some processing of variables in a call file before deciding to make the outbound call.

The problem is that two processes run in Asterisk. I used to be able to tell the difference between the two and route one to 'nullcontext' below so that I didn't get duplication of the call.

Here is a call file:

---
Channel: Local/s@timedcontext/n
Callerid:XXXXXXXXXX
RetryTime:300
WaitTime:30
MaxRetries: 3
Context: timedcontext
Extension:s
Priority:1
SetVar:INTERNAL_MACRO_EXTENSION=wo-notification
SetVar:CALL_EXPIRATION=20071227000000
SetVar:PLAYFILE=2a0103d439882c9e6dc344949efbd198
SetVar:TZ_OFFSET=-1
SetVar:PHONE_NUMBER=17817619228
SetVar:DAVESVAR=<<xmlcalldata>>
SetVar:EARLIEST_CALLTIME=09
SetVar:LATEST_CALLTIME=08
SetVar:IVRUNIQUEID=2a0103d439882c9e6dc344949efbd198
