[asterisk-users] How to capture destination number when receive call through ZAP

[Rob Hillis]

The only method I'm familiar with for an analogue line to signal which 
number was called is a very old service that loops the line first and 
then dials the number.  The only way to capture this would be to handle 
the incoming line as a standard extension with a different context.  
I've only run in to one of these services myself - and that was attached 
to a legacy PABX.  I seriously doubt you'd be able to order these 
services any more.

If this is a standard PSTN service, the only way you know which number 
has been called is by matching it against the zap channel that the call 
has been received on.  The ${EXTEN} variable won't tell you this as 
you've already found out - you'll need to examine ${CHANNEL} and match 
the channel to the connected DID yourself.
