Hi all,
I have two locations connected by a ISDN line and two Cisco 803.
One week ago I had to replace a failed Cisco 803 with a new 876W.
My experience is obsolete when not vanished so I'm in a big trouble trying to restart the link.
After many changes I've been able to get connection and autentication between the 876 and the old 803 but now I get an error I can't solve.
The HPN (876) dial the BFR (803) where I get this (debug dialer on the receiving side):
complete listing of debug is:

The connection is estabilished but the ping fails.
I think this is due to the IP configuration on the new router but can't find a solution.
May be the Vlan or BVI interface are wrong?
Where coul'd I find a minimal configuration for connecting two 876 via ISDN?
Thank you so much in advance.

Hi,
Put some private IP address on Dialer, preferable /30 subnet
and also add route accordingly for the same.
