Called and left no message.  Call is from the same prefix as my cell phone.  I researched this as it is happening with a great deal of frequency.  I'm thinking it's somebody I know and every time I answer, it's been a recorded telemarketer.  I have since quit answering any numbers that have my prefix.  They can leave a voicemail if it's somebody I know.  Sad I have to do that, so score one for the telemarketers.
