I have been getting calls from "not in service" numbers for weeks now. When I call back, sometimes the number doesn't even ring. Sometimes it doesn't stop ringing, and no answering machine picks up. If I answer, I get nobody, but I don't answer anymore if it's not a caller on my contact list.

Missed the call when I called back it said the number was disconnected......weird

Interesting - A missed call on my cell today is first time I have seen the number.  Didn't know wfhat I would get with a search - this is fantatstic.

It call me today and did not say nothing when I answer the phone. Other phone call like this been happen to me for 2 days now

Just called me. Phone rings twice, I answer and they say nothing.

Called cell, said nothing but could hear people in the background
