Re: Evolution of the VoIP market?
The only reason why POTS provides reliability to 911 services is that it was tied in with the 911 system. The 911 system was not designed for VOIP to begin with, it was also not designed for dynamic locations.
A 911 service operator is seeing a screen, when you call all they get is the telco records of what that numbers address is tied too.
Since there is no way to move the line physically, the only way possible is to route it somewhere in a wireless fashion or route it directly to the net. Where you can be in Austria for all we know but you are using your computer to connect to your home server, and from there you open up the connection and place your call.
When you call it still shows that you are calling through your phone line, what address are they going to get? Not the one in Austria, that's for sure.
The 911 system must be updated to get GPS data from cellphones, and be able to trace the source of a call.
But then we get into the whole "privacy" issue and everyone is bent like a nail about it.

This has already occurred, but many areas do not support cellular E911 and there are various phases of this as well. You can blame PSAPS and carriers alike for the slow implementation of this. BUT....This is still not a 100% resolution to things on the cellular side.
There are areas in FLoriDUH which support Phase 2 Cellular E911. Its not perfect, trust me, the number of phantom calls that are chased to "estimated addresses" is quite annoying. Especially when you have a busy shift and these calls are treated as high priority due to the nature they could be anything. 9 out of 10 times its a nothing call, some sat on the phone and hit the 9 button, or hit the wrong key or stuffed in their bag and hit the 9 key, etc.. Along with the flat out lies..."We don't have no cell phone (as some stupid ringtone plays in the background as the call back number is called...  )
Even in the areas that don't have cellular E911, most get at least ICLID (NOT ANI) the way the calls are routed in some areas is not via 911 trunks but just a forward to a POTS line that is programmed into each cell site. With the ICLID it helps to at least call back if disconnected, but the process to trace it back to a customer, get their co-ordinates from the carrier is not speedy and is laborious on the PSAP end.

i can't help thinking that if e911 was fully operational, even more people would drop pots like a bag of moldy tangerines. |

If you have VOIP and your carrier sets up things they can offer E911 service.
The problem arises from the very nature of VOIP. I could be anywhere on the planet that has a internet connection capable of supporting the VOIP link.
So how to determine where I am and route to the correct PSAP if in the US, and if not to route to the correct agency. With out a bunch of rules that would make VOIP useless for those of us not using it for POTS replacement theres not a reliable way to do this for VOIP like cellular and GPS and/or triangulation which are not 100% accurate.
VOIP presents challenges that while large, are not insurmountable with out a making it useful for those using it for POTS replacement, and those using it for out of area DID's, etc..
