Who called from 6265446848

Picked up call and it was silence. Who are you?

Calls my cellphone every 12 hours or so. Rings 3x, never a message. Who are these people?

This is SirusXM satellite radio.

picked up. silence.  must be a spam call.

I've received numerous calls from this number. When my telephone system (1 of seven systems) sees "UNASSIGNED (626) 544-6848" it automatically hangs up on this NUISANCE CALLER. Although I live in New York, I have a phone numbers in Napa Valley, CA, therefore, when I receive unfamiliar numbers, I program than number into my telephone system, therefore all future calls from this number (I've been getting from two to nine calls a day from that number, commencing on 08/05/2014), my telephone system just plays the telco's recording for unassigned or "out of service" telephone numbers — this caller has targeted the WRONG PERSON TO MESS WITH!!
