7937g conf phone randomly dialing an extension, no user intervention

I have a phone that has become possessed.  It's randomly dialing ext 2000, which happens to be Unity.  Firmware is 1.4(4) with call manager at 8.0.3.23900-5.  Not completely positive, but this could have started after we updated to 8.0.3 from 8.0.2.  I have tried factory reset (Applications-**1).  Anyone ever seen this?  I've attached a video of the possessed phone.

I would upload and select the older firmware by selecting the load in CUCM in device defaults. Then factory reset the phone and it will load the previous firmware. ( Im speculating that there was a firmware diffrence between 8.0.2 and 8.0.3) .  If not then this is worthy of opening a TAC case.

Did you ever get this issue resolved? I have had the same problem for quite some time.

You should call TAC... or a priest.

Seriously though, does it happen with any predictability, like at a certain time/day? What version of firmware is it running? It would be interesting to see if it matched Scott's version.
