Hi Folks,
Has someone already been faced to this issue?

It is a very basic DDR config between two routers:

> Problem:
Once I launch a ping to test the connectivity, the B channels raise up, then s
uddently go down after a release "Cause i = 0x82D1 - Invalid call reference val
ue " which means, following CCO:
The remote equipment receives a call with a call reference that is not currentl
y in use on the user network interface.
It seems that the problem is between the ISDN switch and Louis.
I know that it is most likely an ISDN switch issue rather than a Cisco one. Any
way,Can an ISDN Guru help me on that?
Cheers,
Pierre-Alain
