asterisk users - Feb 2010 - billing based on local access number

Hi all,

I am configuring asterisk as a prepaid calling card. I am getting different
local rate from my ISDN provider e.g  0.002 for landline and 0.13 for mobile
etc. In this case I thing I have to say my asterisk/a2billing to bill based on
local access number. so How can I retrieve  called number (eg. 03-6832-1040 and
0120-272-060 is our ISDN PRI access number) to my asterisk server so i can
trigger different rates.

Regards
Umesh

The number the caller called to get to you should be passed to Asterisk
as the inbound extension.  So, in your incoming context, you can
provide different extensions for the different incoming numbers.  Or
you can catch everything with the "_X." pattern and use the ${EXTEN}
variable to check the number in your dialplan.

One thing to note is that it doesn't always pass the whole number.  I
have two PRIs from different providers; one of them passes all 10
digits, but the other one only passes the last 4, and for some reason
with one of our numbers that ends in "9977" the PRI passes
"2977".  You
can either ask your provider what they pass, or you can just make test
calls and log the value of the ${EXTEN} variable with Verbose() calls,
something like this:

[incoming]
exten => _X.,1,Verbose(Incoming call to ${EXTEN});
exten => _X.,n,Playback(welcome);
