I am having this same problem. I can't make outgoing calls. When an incoming call comes in the phone rings and it shows up on the TV who is calling but when we answer it is dead air. I tried changing phones and it has not helped so I klnow it isn't a phone issue, it's a phone line problem. Any ideas on how to fix?
