@TE: We're neither, we're the telco for this customer. I've been told they're running the latest release, but wasn't given the version number.
I'll ask that those two logs be looked at, but I suspect the Mitel reseller has already looked at that. I know we looked at lives signalling traces.
Yes, the customer has been monitoring the T-1 through the CLI and everything appears to be set up correctly, no slips. They have been looking at the D-channel, but when they camp on it for extended periods of time the T-1 bounces -- I'm told that's a known risk when doing that.
