When an incoming call arrives from the ISDN line, look in ${EXTEN} -- this
will contain some representation of the number. It may be missing the STD
code, or just the initial 0.
All* you need to do is implement a rule to translate the incoming ${EXTEN} on
an incoming call, to an extension number, and implement this in your dialplan
in the conjtext in which calls arrive from the PSTN. For example, if you
always want the internal number to be 2 followed by the last 2 digits of
the external number, you could use this minimal example:
[from-pstn]
exten = _X.,1,Set(LAST_TWO=${EXTEN:-2})
exten = _X.,n,Dial(SIP/2${LAST_TWO})
exten = _X.,n,Hangup()
[*] OK, that's not *quite* all. When you make an outgoing call, you need to
set the caller ID to match the external number the person needs to dial to
call you back:
[outgoing]
exten = _X.,1,Set(LAST_TWO=${EXTEN:-2})
exten = _X.,n,Set(CALLERPRES()=allowed)
exten = _X.,n,Set(CallerID(num)=${PREFIX}${LAST_TWO})
exten = _X.,n,Dial(${ISDN}/${EXTEN})
exten = _X.,n,Hangup()
${ISDN} and ${PREFIX} need to be defined in the globals section:
[globals]
ISDN=DAHDI/g1
PREFIX=013322689
; this assumes numbers start (01332) 2689xx

OK. no result isn't very helpful.
I'm presuming you've got internal calls between SIP extensions working
correctly, and something happens (even if it's not exactly what you want)
when you call an inbound number. If not, get at least this much working first.
I'm also presuming that you know a few things about dialplans, and can make
appropriate substitutions in your head.
In your chan_dahdi.conf, what is the name of the context associated with the
span to which the ISDN is connected? (I assumed in my example that the
relevant context was called from-pstn.) Make a note of this.
Now make a copy of your existing extensions.conf, then open the original in a
text editor. In the context where calls from the ISDN line arrive, create the
following extension:
exten = .X_,1,NoOp(Incoming call for '${EXTEN} from ${CALLERID(num)}')
exten = .X_,n,Hangup()
Open an Asterisk console with maximum verbosity, run dialplan reload, call
an inbound number from a mobile phone and you should get a message something
like
Incoming call for '01332268901' from '07892101232'
with some or all of the number you dialled and your mobile number, just before
the call disconnects. (If not, then something else is wrong.)
Now you know how much of the dialled number the phone company are sending you
(complete number / number without leading 0 / local number without STD code).
Next, determine what the rule is going to be to link the dialled number in
${EXTEN} to an individual internal extension (in my example, I assumed that
the rule was: 2 followed by the last 2 digits of the external number)
and devise a dialplan expression that will set a variable to that. (If you
don't know how to do this, please ask, giving some examples I can work from.)
Now, between the NoOp() and the Hangup() lines in our minimal context as
above, insert lines to set a variable from your expression and another NoOp()
to display its value.
Open an Asterisk console with maximum verbosity, run dialplan reload again
to make sure you are using the correct dialplan, call an inbound number from a
mobile phone, and this time you should get another message with the internal
extension number you want to call. Check it with as many numbers as you can
afford to waste credit on.
When you're sure that you have your formula working, add a Dial() statement
which will dial that number. If you want, remove the NoOp() statements;
remember to make the statement which is now first, priority 1 instead of n.
Again, run dialplan reload before you make an inbound call, just to ensure
you are using the latest edited dialplan.
That should sort the incoming side. On the outgoing side, you need to write a
dialplan expression which will set CALLERID(num) to whatever external number
is associated with an internal extension (which will be in ${CALLERID(num)}
-- sorry, I made a mistake and put ${EXTEN} in my first example). basically
the inverse of the first rule. Then put this into your context which is used
for outgoing calls.
If any of this is going over your head, please ask for clarification. (My
preference is generally to overestimate someone's abilities and rely on them
asking questions if lost, rather than sound like I am patronising them.)
