Received multiple calls over several days, with no voicemail messages. Called the number back and it was an auto insurance telemarketing group. Told them to stop calling me and adding the number to my blocked caller list. I have a 206 area code on my cell phone from when I lived in Seattle, so this is likely being sent from this number because of my area code. It's a frequent ploy to get you to answer, given it's a local area code.
