In addition to the config of both routers it may be helpful if you would post the output of show isdn status on both routers.

dsl 0, interface ISDN Switchtype = basic-net3
Layer 1 Status:

Layer 2 Status:
TEI = 64, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
2 Active Layer 3 Call(s)
CCB:callid=802D, sapi=0, ces=1, B-chan=1, calltype=DATA, hdlctype=HDLC-TRUNK
