1. Post output of "show version"
2. Post output of "show isdn status" after interesting traffic (ping)
has been sent
3. Do you get any useful output from traceroute 80.15.236.167 or
traceroute 209.85.129.147 ???
Hopefully this shows you the first hop (ISP gateway) IP address
4. Can you ping the ISP first hop gateway IP address ?

are you authenticating okay during the ISDN call ???
debug ppp neg
Router#sh isdn status
Global ISDN Switchtype = basic-net3
ISDN BRI0 interface
dsl 0, interface ISDN Switchtype = vn3
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 72, Ces = 1, SAPI = 0, State =
MULTIPLE_FRAME_ESTABLISHED
I_Queue_Len 0, UI_Queue_Len 0
Layer 3 Status:
0 Active Layer 3 Call(s)
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< no active call
Active dsl 0 CCBs = 0
The Free Channel Mask: 0x80000003
Number of L2 Discards = 0, L2 Session ID = 3
Total Allocated ISDN CCBs = 0
the ISDN layer 3 status output indicates no active calls so if the
ISdN interface / dilaer
is not up and up, your pings will
just end up in the bit bucket

Thanks' for your reply.
I have haded "debug ppp neg" commande line and in the debug monitor I
haven't more informations that in my last post.
I tryed to add the "dialer in-band" command line and the router
doesn't accept this command !
So I am in the same step of my problem.
Any idea ?
Thanks'
