At 6:53 p.m. eastern time I missed a call that revealed this number. At 7:05 p.m. I attempted to call the number back to determine who it was and was only able to get a constant busy signal.
This number was on my phone as a missed call no message for me and identify who you are calling/representing and why. I will not answer the call about then there will be no answer.
This is not a telemarketer. It is Vector Security. They called me a few times before and didn't leave a message, but it's because they immediately try to call the next number on the list you gave them to call if your alarm goes off or if there's another problem like a low battery.
I'm putting this as Call Type "Event Reminder" because there isn't an appropriate category listed.
