Incoming calls are not accepted.

I attempted to use the blocking service (selective call rejection) during the election.  After I entered the first two numbers to block, the phone does not allow ANY incoming calls.  The caller receives the message, "The number you have dialed is not accepting incoming calls."  I see the caller ID on my TV, the phone doesn't ring.  Even if I see it on the TV, and then pick up the phone that doesn't ring, I get a dial tone.  I can dial out to anyone I want, but no calls come in.  It was actually great during the election season, but now it's more of an issue.  HELP.
