Who called from 4803828109

Same here.  Calls and there is no message, no nothing.  Broken robocall I'm thinking.

This might be the first of collection call.  They call and get your "schedule' and then let the collectors know when you answer your phone (daytime, nightime.......)    I have had several hang up calls at a business phone in the last 3 days and it has been this company.

Just got a call from this number.  When I answered, all I got was music.  First time I have received a call from this number.

Another "dud" phone call...4th one today all from different numbers!

Just got a call from same number. No message
