I did finally try the programming suggestion and the ports behaved the same. My only display phone is ext 10 at the reception desk so I had to wait until the weekend. I also waited for the replacement to arrive so I could switch at the same time if necessary. After installing and restoring it everything works again as it should.

I found a place that said they would try to fix that one for $100 and refund if it can't be fixed - worth a try. The tech thought it was strange that just a few ports quit working. All is well again - thanks for the help.
