Caller ID says ALARMCOMP, which I suppose could lead one to believe that the alarm company which we actually use is calling. However, their caller id display would look nothing like this one, and we did not pick up the phone, and will not do so in the future. We are on the DNC list and should not be receiving this call. This number is now blocked. No message was left, now we won't hear a single ring and will know to watch out for this caller id under a new number, which we will also block. Thank God for Panasonic, who makes number blocking easy and affordable.
