I've used the block caller feature on both my phone and the telephone company (Mediacom) and I've run out of slots on both. Both of them only allow 10 numbers. With these clowns using multiple numbers, it eats them up fast. Any suggestions on how to expand the number of callers that can be blocked. My home phone allows about 3500 numbers to be listed in the phone book, you'd think you could use up some of that space for blocked calls. Who has 3500 friends and family on their home phone.
