If the 911 PSAP supports E911. Well, it's a little more complicated than
that. Your carrier will register your phone number and physical address
in a database. When the call goes to 911, your carrier sends your phone
number along with it. The PSAP then looks up your phone number in the
aforementioned database to retrieve your name. This happens regardless
of whether the call came in via cell, voip, landline, etc. Cell phones
also send GPS/location data somehow but I only know the voip side of this.
At one point 911 for voip was a mess, and it's still no picnic from the
carrier's end, but it is reliable for the user (as long as you can make
a call, of course).
