Can I block my own cell number?

[iamihop]

For the past week, I've been getting a handful of calls each day from "my" cell number. Obviously, some system is spoofing my number and sending the calls at me, for some reason. I just ignore the calls, but it's annoying. If I were to block all calls from my own cell number, does anyone know if this would have any adverse effects, like preventing me from calling voice mail or anything? Thanks!

Also, I can't figure out how they could have gotten my number. In case it helps, my number is (804)-295-583 -- just kidding
