asterisk users - Mar 2005 - How can I eveluate trailing numbers in extensions.conf?

I believe that should have the answer for you. 

furthermore assuming that your number is always going to be 12 digits. 

exten => _NXX.,1,SetVar(mynumber=${EXTEN:0:12})   - will give you your
number.

Hope this helps.

Hi,
  you can use StripMSD if you are sure of the number of dialled digits.
or you can use {$EXTEN:-1:1}, where {$EXTEN:a:b} means first b digits
starting from a, from the front or back depending whether a > 0 or a < 0.

additionally, can have your own variables, just look at
pbx_retrieve_variable in pbx.c

I'm not sure. I have  

register => NNNNNNN:XXXXXX@sipgate.de/sip

in my sip.conf, and in extensions.conf, the "sip" extension knows
nothing
about the called number. 

[incoming]
; exten => sip,1,Goto(isdn,1${CALLEDNUM:-1},1)
exten => sip,1,Goto(isdn,11,1)
exten => sip,2,Voicemail(u100)
exten => sip,102,Voicemail(b100)

How do I set "register" properly to use a simple $EXTEN expression as
above? I did try that before, no luck. (I have some more registrations
in my sip.conf because I want to use a simple LCR strategy).

In any case, I just posted a patch against the CVS to the asterisk-dev
list. This patch gives you a new variable CALLEDNUM that does what I need.
It's used as in the commented example above.
