New user here as you can see

I've had MJ for a few weeks now and had no problems what so ever until earlier this morning when my 911 addess disappeared and everytime I call myself I just dont hear anything, no eror message just dont hear anything.
I'm in the NY (718) area code, and the icon next to the 911 space is red and says "inactive", but yet I am able to send and recieve calls just stuck without 911 and voicemail any of you gurus have any tips or know what might be wrong?
