i have a customer with an old bcm 200 and is now having problems with the ip phones all of the sudden. they will go out and then come back on all by themselves. does anyone have any suggestions on this? i do not know the release of the bcm but it is about 3 to 4 years old. any help will be appreciated.

Are they loosing network connection or power to the phones?

Reboot!!!

But yes, I have had a similar issue, very tricky to troubleshoot. first check to see that the network isn't congested, and that the power to the sets is good.

If all is ok, I would try a reboot on the BCM.
Also, look at installing all available patches, at least the ones which apply somewhat to your issue.

Nickels' recommendations are sound. If the problems persist or return after a reboot, the hardware may be affected by a couple of known issues. There was a run of bad Base Function Trays(motherboard) and there were some alterations made to the MSC. Nortel offered replacement parts free of charge for both issues, but those programs have ended.

I had this happen about 2 years ago. They were all at the same remote location. Check and see if one set reboots more than the rest or drops first. When I replaced the set the that dorps the most the issue went away.

thanx for the help ill try nickles idea on the reboot and patches. i will keep you guys posted to what i find

The BCMs before 4.0 were built around NT and the Windows NT created some flakey problems at times like self-rebooting at odd times.

I used to have strange problems with some BCMs until I started scheduling reboots once a month. After that, rock solid performance.
