I was just wondering if any one knows how I can find out who is ringing my house phone as I don't have caller ID I want to find out who it is then block the number

I would think that if you noted the date and time that you are receiving phone calls that you don't want for some reason and then reported them to the phone company, that they would have a record of them and might enable them to be blocked from using that number or numbers to call your number. As far as finding out who it is that is ringing your number, that might be something harder to find out depending on where the calls are originating from.

Many telephone companies offer the option of letting the user dial *69 to get the last number that called the phone.

Yea I've tried they seem to think they can't do it

Thanks for responding! Are you in the U.S. What kind of calls is it that you are getting that you don't want?
