Auto Attendant Weirdness- Again!

[NimrodMCSE]

Hi all, my weird problem is back. Got rid of it last time by moving affected station module to new port and reprogramming all the phones on it. After about 4 months the problem has returned. Only starts dialing numbers after being on "nights" for more than 24 hrs.Here's the problem-Having a really weird problem with my MICS 4.0 with Voicemail 4.0. On weekends I'll have phones that will automatically start dialing the last number called from the set. I've noticed this to be happening only when the Auto Attendant is on. Also if this starts happening on a weekend, by the time monday rolls around the Station Module that these phones are attached to will cause all sets connected to it to have the "Flashing arrows" display or no display at all and the sets will be out of service.Once I power the Module off & on and it synchs with the system everything will work again.Also these phones will go into "Hands Free" at the same time as it starts making calls. Kind of spooky while working on the weekend and having all the phones around you start dialing for theirselves. The local Bellsouth Guys don't have a clue.Looking for any insight. Already disconnected the RAD and Changed all the passwords thinking it could have been compromised. Maybe some kinda virus, or other bug? FYI, last time tried swapping out station module with spare, did not help.

It sounds like only the phones on the Expansion Station Module? Is it a copper or fiber Expansion Module? Is there a UPS(battery backup) on sytem? Have you had electrician check electrical to see if properly grounded?

Yes only on the expansion station module and it's fiber. Also the module is extended thru the fiber extension kit to another floor in my building. Goes from card to extension kit to another floor to the problem module. The problem module is not on an UPS but the Primary (Core system) is. Haven't checked for ground problem.
