Sorry about forgetting to post that, but, after much trouble shooting, it was determined that the cam is bad, the intercom works, and doesn't work intermittenly, so I will replace the cam. Also that particular phone is the only one that does that. I tried switching to another phone, I defaulted everything that I could. I went to pages 20 and 24 of the manual for option # 26 as recomended and applied those procedures.
