According to my correspondent, number and name showed up on their caller
ID. ATT uses "AnyWho" to associate name with number. Sorry, but I do
not know any other details of how it works.
I do know that for 911 calls it is an ATT responder who must forward the
call to the local police/fire/ems based on the information that the
subscriber (me) entered into the CallVantage system. I have *heard*
that that (2nd) call does not arrive at our local constabulary with the
appropriate hardware generated information to trigger the E911 system
that our town has. In other words, the 911 caller (from my house)
really needs to stay on the line. Can others elaborate on this?
