Hi there,
I just recently installed asterisk from cvs on SuSE 8.2 successfully. I was
quite surprised since asterisk seems to be a quite complex and powerful
application. I also installed chan_capi 0.3.5 and am using a Fritz!PCI card at
an ISDN line (PtMP).
I already got some basic extension schemes to work, e. g. the capi callback
example from junghanns.net. One of my goals is to set up an extension for the
capi channel that will allow me to forward a call (incoming on one of the
ISDN b-channels) to another outbound destination. So, in the following, X is
my local MSN and Y the destination that I would like to forward to.
(1) I tried the call deflection (capiCD) example from Junghanns which does not
work. I was wondering if you need some services activated from your telephone
provider (here: DTAG in Germany, Standardanschluss). There is just nothing
mentioning it on junghanns webpage. Can anyone confirm that?
/var/log/messages shows:
Sep 20 21:33:17 themistokles isdnlog: Sep 20 21:33:17 * Call to tei 122 from X
on Y HANGUP Invalid information element contents (Public network serving local
user)
The same happens with capiECT which I tried from the examples. But I am pretty
sure that you need a service activated with your provider (so I am not
surprised about that).
(2) On the other hand, accepting the call and immediately calling the
destination Y on the other B channel should work. I tried
exten => s,1,Answer
exten => s,2,ResponseTimeout(30)
exten => s,3,Background(/var/lib/asterisk/sounds/hello)
exten => t,1,Goto(s,2)
exten => i,1,Playback(/var/lib/asterisk/sounds/invalid)
exten => i,2,Goto(s,2)
exten => 1,1,Dial,CAPI/XXXXXX:XXXXXXXXXX|30
But I always get an error message:

Why does * say that the second channel is busy?
/var/log/messages indicates that the call was executed. the HANGUP happened
when I terminated the first call.

Any hints would be greatly appreciated. Thanks.
