recurrent calls by this number; assume it's someone's polical campaign number although it is wireless

I too have received 3 phones calls in the last three hours by this caller. They always hang up. When we tried calling it back it was busy.

Continue to receive calls from this number.

Repeated calls each and every hour. The politician Bonamici's spambot phone dialer... I requested to be put on a do not call list from the campaign, but she obviously doesn't care. One more reason not to vote for her.

This number has been calling several times a day for several days -- probably 5 times so far this morning. I don't answer and they never leave a message.  I found this number reported a couple of other spam websites as well.
