A standard PSTN line will not give you the number that is connected to
it - Asterisk has no way of knowing what it is. What I mean by matching
the zap channel to the number is that if you know that the phone number
123 is connected to Zap channel 1, then when you get a call in on Zap/1,
then the line that was called was 123.
An E1 line /can/ give you the details of the phone number that was
called, if your provider supplies it.

Dear Rob and all,
I also tried $CHANNEL before but it returned:
-- Executing [EMAIL PROTECTED]:8] NoOp("Zap/1-1", "channel = Zap/1-1") in
new stack
It still does not give me the dialed number. Could you explain how
to match it again the zap channel to extract the dialed number?
Will I be able to get the dialed number if I am using a E1 line?
Thanks,
Mark

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
