(PM) OSPF Routing with Dial-Out -- How? (Am I just dumb or what?)

Hi everybody, thanks for listening.

Here comes my problem:

I have an PM2 with 5 ISDN BRI interfaces. A customer of mine has
another ISDN router and wants to set up a dialup connection with
dialback (e.g. whenever a packet for him arrives, my PM2 dials out, he
refuses the call and dials back). That part of the problem I have up
and running. He is using a "Brick XS" router from BinTec, which reject
my call and while the PM waits the retry time he dials in and
establishes the connection.

Here comes the problem:

(Customer has Subnet 192.168.1.0, connected via 192.168.1.1)

centipede> show location customer
Location: customer Type: On Demand
Destination: 192.168.1.0 Netmask: 255.255.255.0
Protocol: PPP Options: Quiet, CHAP
Group: 1 Max Ports: 1
Idle Timeout: 5 minutes High Mark: 0 bytes
Mtu: 1500 Async Map: 00000000
Username: myname Password: wonttellyou
Telephone: 12345678

centipede> show routes
Destination Mask Gateway Source Flag Met Interface
----------------- ---- -------------------- ------- ---- --- ---------
[...]

-> No route for 192.168.1.x is in the PM Routing table.

centipede> ping 192.168.1.1
no answer from 192.168.1.1

centipede>dial customer

centipede> show sessions
Port User Host/Inet/Dest Type Dir Status Start Idle
---- --------------- ---------------- ------- --- ------------- ------ ------
[...]
S11 customer 192.168.1.1 Netwrk In ESTABLISHED 0 0
[...]

centipede> show routes
Destination Mask Gateway Source Flag Met Interface
----------------- ---- -------------------- ------- ---- --- ---------
[...]
192.168.1.0 24 192.168.1.1 temp NS 1 ptp11

as you can see, now I have a route.

What can I do to get this behaviour? I want to have one (or many)
customers, which are connected over demand dialup locations. But my
PM2 does not have routes for their subnets in its routing table and
(even worse!) does not report such potential routes via OSPF.

How can I set up the wanted behaviour?

Kind regards
Henning
