Does the Software module hold the programming database?
I have a system that I am thinking that I need to swap out.
Can I move the module over to the new system and will the programming transfer over also?

The system is a GO 816 with a GM 408 expansion module. Impact phones.

A side note: the problem with the system is that sometimes when on a call the call will go dead. The phone does not go dead, the line appearance still shows the call still there.
I did some testing and found that the call is not dropped it is just that the user at the comdial phone cannot hear anything.
If you press a touchtone key on the comdial phone the call comes back. It is like the voice path between the phone and the system is cut off and is re-established once the key is pressed.
This happens about 5 times an hours, can find no pattern, it has happened when I was the only one on the phones.
It also happens on all phones and is not tied to any particular line.
It has me baffled, I can see no other option than to replace the system.
Thanks
Don
