After fifty5's last post I went back and looked at this thread. I may have missed it, but I can't find anywhere where it says the outside calls are being answered by an auto-attendant, but it seems that would seem to be the logical assumption here. However I wonder it that is what is happening. Are the outside calls being answered by an auto-attendant?

It seems to me the way to make this work with what you have is to have people program a single digit on their mailbox to dial their cell ("to try to reach me on my cell press 1").
people have a great tool with the voice mail to inform people of what they are doing and when they will be back but most people don't take the 15 or 20 seconds to record their greeting in the morning and at night. Just lazy

Vendor show up out of nowhere and did a long convoluted call into Mitel to figure this out. Turns out a COS option of "Suppress CCM for ISDN" (whatever that means?!?) was the option to enable to fix the problem. Apparently it affects the behavior of certain call routes, even the explanation in help was a bit convoluted.

It now works as prescribed!

Thanks for letting us know - I have never run ito that.

Learn something new, I had to look it up.

CCM = Call Connect Message, in response to the CO’s Call Progress Message…

From the Knowledge Base (just put in CCM)
