ISDN Drops Calls?? Capture attached
Hello everyone, we are tryint to setup an ISDN connection and are running into problems. We are using a Cisco 1600 (1604?) to do this. The connection is to qwest.net
The call gets connected and we are able to pass traffic to the Internet... however after a about 2-3 minutes the channels will drop and then connect back up again. This occurs while we are sending continous traffic out to the internet.

Thank you for the replies... Well the lines have worked fine for over a week... and happened to start dropping again today. I called the teleco and they said they can connect to use fine. However they do not see our SPIDS in their switch and never have. My status on the router says that the spids have been send and accepted?? So I am not sure why they are getting this. They think it may be a problem with our extended demarc and we are checking on this. Any ideas on how to arm myself to yell at Qwest? We are seeing crc errors also..

Well I face similar kind of problem.
I was able to make a test call but that call used to drop after 20 seconds. I informed telco about it, but they sais it is not their problem.
The site was in a small town.. there were no other isdn customers in the town other then us. I called the telco engineer to our sub office and explained the problem. He understood it.. and decided to change some things in what they call as an ISDN tub. He changed the ISDN card in the ISDN tub and then it started to work very well. Our enterprise consists of 64 sub offices.. 3 of them had the same problem.. and the same solution was used.
this is 100% an issue with telco.

Given these error counts, I agree with scrathyboy that is is generally a telco issue.
If the link works at all, it is not typically a configuration issue on the router.
However, the vast majority of IOS bugs that I've personally run into have been related to ISDN. You may want to update the IOS to the latest that your router will hold. I had basically same issue with some 804's and had to upgrade to 12.3.15a from 12.2.31
