bust out the user manual for your caller id. I promise you, that if it is even half-way decent, there will be a page in there describing to you how to ignore calls that cannot be traced.

this will work, if your phone has this option. If it does, tell anyone you want to talk to that may call you from a cell phone, to turn on the 'Send My ID with this number' option in their cell phone, or their call will be ignored also.
