I might be missing some point here, but what's the deal?

That is the PBX supplies an internal S0 (NT-Mode)?

My Hicom300 has 4 internal S0, each of which is configured to use a
range of MSNs.
chan_capi is configured for the MSNs accordingly.


Are you asking to use the PBX in PTP-Mode?
There is a short description in chan_capi.conf

;PointToPoint (55512-0)
;for outgoing calls use example 5551212
;and in dialplan you can use callerid like
;exten => _0XXX.,1,StripMSD,1
;exten => _XXX.,2,Dial,CAPI/55512${CALLERIDNUM}:bBYEXTENSION
;============================================================
;mode=immediate
;isdnmode=ptp
;msn=55512
;controller=2
;devices=30

I'm not sure though if the Fritz!Cards support PTP ...


Just trying to help ...
