Who called from 6673083980

Caller ID said ALARMCOMP, no message. This number is spoofed.

Got a call from this number. Did not answer. Did not leave a message.

This number keeps calling. ID says only "Towson". No one there when I say hello. They call several times a day.

Call from this phone number, but it had my son's name in the CID.  Weird.  Did not answer, no message left.

VOIP Neutral Tandem out of Towson, MO.  When the answering machine kicked in, there was some loud feedback until I could disconnect the call.
