ISDN PRI dial in problems

Hello all, I have been trying to configure a Cisco 3745 as an access server with a PRI module for ISDN dial in. The problem is that the incoming call does not last more than 7 - 8 secs.I am including snippets of the config as well as some debug output. I'd be grateful if anyone can help

- I just cant figure out the error messages.

Thanks in advance, Shireen

I would start with:

deb ppp auth deb ppp neg

Since the length of call seems to indicate problems there.

I also googled for qsig event 0x4a and it seems like that might indicate a far end disconnect. It can be instructive to get the same debugs from the far end. Make sure you have ntp configured on your routers so you can match times in the logs.

HTH,

The debug below is telling you that PPP authentication failed

Without seeing the rest of your config I can only guess that you have not configured the authentication method for dialin.
