Hello,

Looking for a hint or two.

I have(had) a Vodavi STS system with fourteen(14) 24 button phones that (had) been working just fine for about 14 years.
Then all of a sudden all phones went dead with the start up screen on the phones displayed with "NO SYNC".
I first powered down the system and disconnected all phones, pulled and reinserted all cards. VM, Station, Trunk
Powered up and waited about 2 minutes and then started to re-connect each phone one at a time. System
came back up except for one(1). Figured that it was the problem so I took it out of the system. All back to normal!!

Then 3 hours later it happened again. This time did the same as the first but nothing helped.

My question is which board would be the most likely to cause a NO SYNC??

Mother Board??

Voice Mail board??

Station Card (2 ea.)??

Trunk Card??

I am thinking the Mother Board, but then again???

Thanks for any input!!!

Have a good day.

Les
