I see two problems:

1: Doesn't asterisk see a pots-call as answered as soon as it has 
"pressed the last digit" and therefore will speak into the ring signal?

2: Often callers are answered with an automated message "This is 911, 
please hold", just to give pranksters/misdiallers a chance to hang up 
before "disturbing" the operator. Unless 911 records the incoming call 
right from the start, they will never hear the "im-at" message. And even 
if they do, they have to know the message is there to seek on the recording.

An option of  the operator receiving a loop of "This is a call from the 
Mickey Mouse building room 123, please press * to receive the call" 
would require the operator to be able to press "*", not sure I'd depend 
my life on that...
