asterisk users - Aug 2008 - app_jack and calling with pc only

Hello everyone!
   Sorry, if the whole task is silly, I'm new to this.
   I have my newly installed asterisk (1.6.0-beta9) and my AVM Fritz a1 card. I 
have a simple German isdn line and I have a microphone, headphones and a 
running JACKd (JACK Aduio Connection Kit).
   The question: Can I (mis)use my asterisk CLI interface to make and recieve 
calls coming in/going out via the ISDN-card, while using my soundcard I/Os 
under JACK as a phone?
   Why I'm doing this and not use another app:
1. I'm blind, I LOVE my console/commandline
2. I tried linphone with SIP, didn't work. JACK crashed and the firewall is
in
the way.
3. The others don't have JACK and I need my JACK running (soundcard too big 
for the simple ALSA stuff and I'm a musician often in need of JACK's
services.
   So asterisk seems to offer all I need. I know it's meant as a SERVER, but
with all this horse-power: Is a simple client so far of the track?
   Kindest regards
          Julien

Yes, you can.  You actually have two options for doing this.  One is 
using app_jack and the other is using chan_console.  chan_console uses 
libportaudio, which supports jack as an audio backend.

To initiate a SIP call from the Asterisk CLI and connect it to app_jack, 
you would use a command similar to the following:

*CLI> originate SIP/1234 at peer application Jack i(outputport)o(inputport)

Using chan_console, you have various call control CLI commands available:

*CLI> console dial <extension>
*CLI> console hangup

While using app_jack will give you more control over how you connect to 
Jack from the Asterisk CLI, using chan_console will give you more of a 
normal phone experience, as it will play tones to the audio interface 
that you normally hear when using a phone.

If you have any suggestions that would make app_jack or chan_console 
easier for you to use, then please let me know.  Feel free to contact me 
directly.
