I have another 804 Cisco ISDN circuit that the router does not connect. I've ran some debug loggging on it and here is what I'm getting, it seems to be an ISP authentication issue, but not totally sure. Please take a look, THANKS!

Ok.. after hrs of "discussing" this issue with the ISP, asking them to test our account login from their end, which they said they couldn't do, I "asked" them to change the password to the password we were ASSIGNED from this ISP. After this change was made, oh and then telling us we needed an @domainname.com after our username, which was not in the tech setup information. the circuit now connects! Go figure.

so moral of the story, make sure the ISP verifies your account information before installation. Save you time and headaches...
