asterisk users - Jul 2004 - Using SIP phone to dial out using ISDN ?

Hi,

I finally got Asterisk installed using the German installation CD from
http://www.asterisk.de.ms.

I got two SIP phones working (SIPPS) 

 asterisk*CLI> sip show inuse
 Username        incoming        Limit           outgoing        Limit
 5678            0               N/A             0               N/A
 1234            0               N/A             0               N/A

 asterisk*CLI> sip show peers
 Name/username    Host                 Mask             Port     Status
 5678/5678        10.0.0.53       (D)  255.255.255.255  5060     Unmonitored
 1234/1234        10.0.0.199      (D)  255.255.255.255  5060     Unmonitored

and the ISDN card seems to be installed correctly

 asterisk*CLI> capi info
 Contr1: 2 B channels total, 2 B channels free.

To make the setup complete: how do I use the SIP phones to dial out through
the ISDN card? Where and how do I configure that?

Hopefully the other way around (ISDN to SIP) is similar and then
self-explanatory.


cheers,
Mike

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.
