Who called from 9712201183

Got 2 calls back to back.  I answered both and no one was there either time.  Nice!  I blocked them.

Political survey call...caller ID just said Pacific Tel.

Politcal survery. Call the number back and press 1 to be removed. They shouldnt call again.

Got a call from this number, answered and got no response, called then hung up after about 15 seconds. How on earth do you block numbers?

Just did what you mentioned and 'removed' myself from their lists. Unfortunately I recognize both recording voices and have attempted to remove myself from their list at least once before, and they still called back...
