[Asterisk-Users] Using SIP phone to dial out using ISDN ?

You could use DeStar (http://www.holgerschurig.de/destar.html) to generate 
a config for you. Simply add a "ISDN Capi Line" and give it the extension 
0.

Currently DeStar is getting full support for contexts (yeah, I used only 
"default" when I made my tests ...), but it is not yet there. So you have 
to put change in the generated configuration this:

file /etc/asterisk/extensions.conf from:

  [out-national]
  ; National calls
  ignorepat=0
  ...

to:

  [out-national]
  ; National calls
  ignorepat=0
  include=out-pstn
  ...


I'll write today or this weekend the code to make this (and other 
wonderful things :-) working out-of-the-box.




So, enought of the commercial: you can also use this line:

  exten=_0.,1,Dial(CAPI/112233:${EXTEN:1},60,TR)

in your dialplan. The 112233 is the your MSN.
