There's so many of us having ATA187 problems. I wish Cisco would do something about it. I'm lucky to have a bunch of 186s so I just replace 187s with 186s.

This really sucks. I was hoping there's a way to have them register as SCCP devices. I'm having lots of trouble with 187s but not with 186s

Yes, but I'm not sure I understand what the problem is. Please clarify

My apologies for not responding to this when I found the solution (which was a few years ago). The problem was DHCP. I ran out of IP Addresses. After increasing the scope, it worked fine.

I have exactly the same problem. There seem to be a lot of people with a similar problem in the 'Support Community' but no real fix or solution. If anyone can help, please...show switch detailSwitch/Stack Mac Address : 0023.5e0f.da00                 ...
