asterisk users - Aug 2004 - determining what number was dialed?

Hey all,

I've setup * to serve the needs of our small helpdesk and I'm looking
to expand. We're planning on doing support for different companies,
each one identified by a different 1-800 number that terminates at our
PBX. What I would like to know is: is there a variable I can read to
determine what number any given caller dialed? I'd like to be able to
separate calls based on who called 1-800-777-7777 and who dialed
1-800-555-5555, for example.

Thanks,

-paul

Yes, but it depends on what type of telephony signalling you are using
as to whether or not you can get that information.

Tells us about your PSTN connection.

Thanks for the information. Sorry about tossing that Caller ID tidbit,
a separate train of thought appeared while I was typing that last
reply.
