Re: Experiences with 911 calls and SIP

I can't see any reason it wouldn't be possible with appropriate cooperation
from the Telco and Government agencies involved.  However, the real question
is how do they know the location and which PSAP to route you to.  Your
SIP phone could be anywhere in the world, literally, without changing
anything
about it's SIP registration other than the IP address (and, with VPNs, maybe
not even that).

If it wasn't crypto-signed, it probably didn't come from me.
