asterisk users - Jan 2004 - CAPI, transfering thru a 2nd PBX - keep original CallerID

Good day,

I want to have Asterisk as my gateway to the outside world and use 
another PBX to connect my existing phones.

How do I specify the dial string to forward the original Caller ID to 
over the ISDN to the second PBX?

Right now, my extensions.conf looks like this:

exten => ${OUTSIDEMSN},1,Dial,CAPI/${MSN2NDPBX}:${EXTEN}

How do I transfer the caller Id information initially coming in?

Any and all help is greatly appreciated.

I have strong doubts that this can be done at all. One way would be to 
set your ${MSN2ndPBX} to ${CALLERIDNUM}, but that would require that 
capi.conf has that CALLERIDNUM listed as one of the valid outgoing MSNs. 
Since you won't know in advance who'll call that'll be a problem -
also I
don't think you can reconfigure capi.conf in the midst of processing a 
call...

Besides: I suppose your ISDN PBX (which brand exactly?) supports CLIP (or 
comes with an internal S0 bus) and you have an analog CLIP phone (or ISDN 
phone) connected?

Workaround: See my last posting and other very recent discussions 
concerning a simple tool that shows the current caller ID and name on 
your PC using either Flash, HTML or Java. Or use astman/ gastman. 
As of now I am storing the caller data through AGI in mySQL and display 
that on a web page that the user needs to re-load manually when desired.

Cheers, Philipp

Correct. It would save me from buying FXS cards. (The PBX is a Gesko 
2108 Office).

Thanks for pointing out your workaround. It is a feasible solution for 
times when the computer is near the phone, most of the time, the phone 
is away.

The alternative is to patch chan_capi to your needs, or ask kapejod to do 
that for you.
