Ok stupid question. When you get the systems do you initialize them then download the datase then program?

Yep, stupid question.

It seems our issues may well be caused by the CLEC interfaces. When NEC looked at our databases and called in to the systems two somewhat related issues showed up. One location had line voltage higher than normal and our office both transmit and receive was too hot. The line balancing program could not properly compensate.

Now, it may or may not be the issue with the voicemail, we'll have to wait and see if it clears up. I now know what to look for and what to do in certain specialized cases.

There's also some changes that can be made for momentary fade out of calls. It's all a LOT more complex than I ever would have believed. As to why the DSX didn't have issues with all of this I have no idea.

Well the SL1100 is basically a dumbed down UX5000. Understanding these systems the actual programming is an overlay of the hardware that is initialized. The same procedure I have used since the nitsuko I-series because in essence it's pretty much the same idea. IF you don't first init these systems and let them properly identify the hardware you can have weird issues. Not sure how hot telco lines cause problems with internal vm calls.

Initial indications are in fact too hot of lines are the problem. Tech support seems to be aware of this and is trying to track down what it is.

At least so far the customer we were having a major problem with this hasn't faulted yet. We trimmed -4.5db transmit and receive on all lines.

Anyway, ALL the issues were CO related, not internal.

Deltron did you kick the lines down at the Demarc or thru the SL1100. Who is the carrier...
