asterisk users - Jul 2009 - MISDN/asterisk problem (not sure where from)

Hello everyone!
   I'm sorry I can't be more specific. So here's the setup:
a Samsung router with analog and ISDN ports. the phone company says the 
outgoing line is analog landline, but I'm sure it's some VOIP.
   so connected to the ISDN port of the router is a Fritz AVM card, used with 
mISDN.
   when I try to make a call with asterisk I get something like this:
cli>> originate mISDn/1/08001507090 \
application Jack i(system:playback_1)o(system:capture_1) <ENTER>
P[ 1] empty_chan_in_stack: cannot empty channel 255
cli>> P[ 1]  --> Didn't find BC so temporarly creating dummy 
BC (l3id:30004) on this port.
   Or I get this:
hdlc_down unknown prim(280)
[Jul  3 14:23:29]     -- Launching 
Jack(i(system:playback_1)o(system:capture_1))
  on mISDN/1-u2
cli>> Huh?  Child handler, but nobody there?
cannot read server event (Connection reset by peer)
cannot complete execution of the processing graph (Resource temporarily 
unavailable)
zombified - calling shutdown handler
cannot send request type 2 to server
cannot read result for request type 2 from server (Broken pipe)
cannot send request type 2 to server
cannot read result for request type 2 from server (Broken pipe)

   Is my setup simply not able to do ISDN or is it something with the JACK 
stuff? I'm running asterisk 1.6.0-beta9 on a Linux 2.6.23 Kernel.
   Can anyone help me in figuring it out and working on a solution?
   Kindest regards
         Julien

I may not be the best one to answer this because it sound like European
ISDN, but there seem to be some basic issues that might be relevant
>a Samsung router with analog and ISDN ports. 
I'm not sure what this has to do with the voice side of things.  An ISDN
port on a router would generally imply that the purpose of the router was to
pass internet data over an ISDN, something that was quite common a decade
ago, but has largely been supplanted by higher speed methods (DSL, Cable
modem, etc).  Some such devices did have the ability to pass voice traffic
through to an analog port (FXS style).  I use such here in my home office,
although at the moment, strictly for voice.
>the phone company says the outgoing line is analog landline
That is easy to test, hook a phone directly to it and see if you get dial
tone.  If so, then there is no place for an ISDN router in this except if
you are using the analog line as a dialup backup for data (assuming the
router supports that).
>but I'm sure it's some VOIP.
Oops, we have a third technology that popped up here from nowhere.  VOIP is
carried over the internet or a LAN/WAN.  It has nothing to do with either
analog voice or ISDN.
