Gari :-)
Oke.. this is what I found...
I have tried the sample config you gave, it doesn't work. The isdn link is
up (for calling router using first B-channel, and response router using
second B-channel) but ip packet still can not go through and I still get
"encapsulation failed" message for ip packet.
I think we need to understand how the basic operational for this config.
When I tried to combine where router1 using "dialer map" command and router2
using "dialer string" command, it's work but only router1 may generate the
call. if router2 generate the call, it won't work !.
so How do you thing..
any idea from group ?
