I get this every day.  I don't answer and they leave a voicemail, "If you'd like to be placed on the do not call registry, press 1".  Then it stops recording. No idea what company it is coming from altho it's a NC area code and that's where I live. The ringing annoys me.  The lack of identifation on my caller ID annoyms me.  The lack of a company name on the voice mail annoys me.
