I have been getting calls from DIDX 567..... something or other I think is the number. Anyway, I use this "Selective Call Rejection" feature on my phone which is "*60" then it gives directions.
There have been some other numbers recently too so as soon as they call again I will add them to my blocked list.
This feature comes with my phone plan but I don't believe it comes with all phone plans.
It tells the caller that I am not accepting calls at this time and it won't even ring through to me.
I might drop my home phone anyway and get one of these here cell phones. I haven't owned a cell phone yet so I'm thinking it's about time I tried it out.
