Simply google for "PS/ALI". That's a TDM product. http://www.e911institute.org/Roundtable%20and%20Tours/June%2024,%202004/VoIP %20E911%20Issues.pdf Page 9 offers a better description of the current E911 issues. It's a software problem. All Vonage does is map your 911 call at the PSAP to your local EMS. This is a 6/24 doc. It's slightly outdated. -M< > > John >
