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.

Hi all,
I am using Digium PCI board to receive PSTN call through regular phone
line. It is no problem for me to receive calls, but I am not able to
capture the destination number through the ZAP channel
exten => s, n, Verbose(1|destination to ${EXTEN} )
${EXTEN} returns 's' instead of the actual destination number. Since
I have multiple phone numbers, I want to be able to route different
calls to different places.
Is this possible to do with Asterisk?
Thanks,
Mark
