Having received about a dozen or more calls from this number, I finally answered. They said they were from the political office of Brian Strickland. Politely asked that they remove my name from their list but we all know how that goes...
When I receive calls from a suspicious number, I add it to my contact list as "DO NOT ANSWER 1 or 2...etc." Then I put the settings to go directly to voicemail. As always, it is best not to have much information on your voice message past your first name for safety sake.
