We have a 1721 at a remote location, and a 2821 at our local site. We are trying to get the remote site to call in and connect to our local site via ISDN. The 1721 has a BRI interface. The 1821 has a PRI interface.
The 1721 ISDN connection attempt almost immediately dies. The 1821 does not even receive any traffic coming in. Both circuits have been tested and verified by the ISPs.
It seems that I am missing something in the config.
I am attaching the config of the remote router that is trying to initiate the connection, the config snippet of the local router that is supposed to receive the connection, and the ISDN debug outputs/status of the remote router.
I have a ticket open with TAC, but they have not been very helpful so far. Does anyone notice anything wrong/missing in the configs? I find it reasonably hard to believe this is a problem with the ISPs at this point.
