If they had to go through a "special" process, then no. That would
indicate that Vonage still doesn't have PS/ALI, at least in your friends
market.
That "special" process is Vonage determining the "default" PSAP in your
area and routing your 911 call to the 7-digit number for that PSAP.
With PS/ALI, Vonage wouldn't be doing the routing. They would hand the
call off to the 911 Selective Router which would THEN hand the call off
to the appropriate PSAP based on a DIG to get your ALI information.
For those of you unfamiliar with how E911 works, and specifically,
PS/ALI, take a look at:

Or... Simply google for "PS/ALI".
