i have :

Router#sh isdn st

Global ISDN Switchtype = basic-net3

ISDN BRI0 interface

        dsl 0, interface ISDN Switchtype = basic-net3

    Layer 1 Status:

        ACTIVE

    Layer 2 Status:

        TEI = 77, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHEDi have

    Layer 3 Status:

        0 Active Layer 3 Call(s)

    Active dsl 0 CCBs = 0

    The Free Channel Mask:  0x80000003

    Internal Multi-drop Termination is ENABLED

    Total Allocated ISDN CCBs = 0

============================================

it seems that i have L3 issue ,

i can see that L1,L2 is fine , but L3 dont have active calls ,

i tried ping to initittae traffic but still no benefit :

Need help in Troubleshooting ISDN over chap authentication !!!

I see in the config that Dialer1 is set to authenticate using Chap and that a hostname is supplied. But I do not see anything that supplies a password to be used in the Chap authentication.
