Who called from 2673315689

This number has called me at least 20 times over the past 3 days and at virtually any hour of the day, each time saying nothing when I pick up. The caller ID shows Gateway. Looking online, however, it shows that the number is listed to Mcn Consulting Group located at 124 Clements Bridge Road, Barrington, NJ 08007 (p) (267) 331-5689. The business information reads as follows: License Number: 093281; License Held: Home Alarm Company; License Status: Active Update; Date License Issued: July 9th, 2012.

This is extremely annoying, and phone companies need to stop selling customer information.

Does anyone know how to stop these calls without having to answer them ? I answered once and there was no one on the line. Thanks.
