That was it....

I just dialed 1 then hung up the receiver (Not by pressing Rel) and the set now has a 1 stuck on it.

Well at least now I know what is causing the problem. What release should I have and how do I find out which one I have.

I thought the version number would be under Maintainance -> System Version but this says:

"SP: 30CQG05 NAT"

Is this correct?
