It looks to me like you are stuck in the INIT phase of the neighbor
adjacency process. See if you actually have layer 3 connectivity to both
routers through the ISDN line (show isdn status). Do a ping and try to bring
the line up. Post your full configs and reboot the routers.
You DO NOT want to use nonbroadcast and the neighbor commands.
Seems you left out your dialer-list in the configs below.
