I have received calls from this number two or three times in the past couple of weeks on my cell phone. When I answer there is silence and then my call is disconnected about 3 or 4 seconds later without any feedback or noise on their end. When I tried to call back, all I got was a busy signal.

caller called my house 2 time in a row and said nothing

The caller called my house and all I heard was static.

This # just called my cell phone and all I heard was static.  These are definitely becoming more and more common.  I was actually on the Better Business Bureau's website filing a complaint about another # that calls all the time when this # called my phone.

Called, rang twice, I picked up, no sound on the other end and it the disconnected a few seconds later.
