Ok guys need some help with this.... Have a system with the 4.0 software. what it does is the customer has the call then all of a sudden the call gets dropped from the system...but...when the customer presses the line button that the call was on the caller is still there and they have no idea the call was lost. we have changed out 3 systems and exp boards. changed phones, power strips, grounded the system. any help would be greatly appreciated. this has been going on for months and tech support has been a bit lacking frown

What kind of lines are you using in the system, who is the provider and how are the lines delivered, by copper or modem or sip to analog? In my opinion this is not a hardware problem, not yours anyway.

The lines are coming in by comcast cable company. We have tried messing with the disconnect setting to no avail. Before comcast they had verizon copper lines coming into the system with the same problems.

Check the CO timers in PGM 180, specifically the call restriction timer which should be set to 0

CO Call Restriction Timer -- N/A
If value is set to 0, the time of outgoing CO calls is not
restricted. If value is set to a non-zero value, outgoing
CO calls are disconnected after the designated time.

Also check the CO release guard timer.

CO Release Guard Timer - designates the amount of
time before a CO line can be re-seized, after a CO call
disconnects; controls the time necessary to
guarantee an idle loop state when a line is released.

Check to make sure you are getting the proper voltage on the lines from the carrier. Since they had a similar issue with their last carrier with copper lines, and the fact that you have replaced everything on your end, the only thing left would be a corrupt database. If you are uploading the old database after each replacement, maybe you should try programming it from scratch. Wouldn't hurt to put a UPS on it either. Not much else left to try.Good luck!

I think adteldon might be right. If you have you have changed everything in the equation accept for the programming, try reinitializing and reprogramming.
