Hi.
We have a 3640 router used as access-server.
It's connected to an ISDN Pri line, and all works properly.
Now we need Pri line for other purposes, and our RAS users are very few.
So we have attached router to a BRI connection, and configured this to achieve same work (remote access connection).
But this doesn't work, when we try to connect from a PC to the BRI line, error is:

We have tried to change ios to last release yet.
thanks a lot for any suggestions.

I believe that the issue is that while the PRI was able to accept both digital and analog calls, the BRI is accepting only digital calls. The incoming call is not digital as shown in this output:
Origination address is non-ISDN
and in this output:
ISDN BR2/0: Event: Received a VOICE call from
HTH

Thanks for your suggestion.
I've tried without PRI card, but it doesn't work. Error message is:

Hi,
do you have "modem dialin" and "no exec under" line xx-yy ?
01-22-2009 12:07 AM
Yes I have.
And Remote Access from Primary ISDN line work properly.
This error come on only if I try to connect from BRI lines.
Is it possible that Pri use modems and take them not possible to use anyway?

What is the WIC HW revision ? check "show diag". There is a minimum to work with the DM.
By coincidence, just yesterday I prepared such a configuration, and it was working fine.
But I didn't had a PRI card in router.
