Not really... it can work. The problem is that CT has always been a "hometown castle" and no one wants to give up their fifedom.
If implemented properly, it works well. I was fairly against the idea of it back when first proposed in 2000, but having worked with PSAPs in other areas of the county, it works great with reduced costs.
I worked for a county out west that is larger than the entire state of CT (8000+ sq miles) with a population of over 600,000. The fire department ran with 3-4 dispatchers and the sheriff's department ran about the same depending on time of day etc. CHP had their own as well as one of the city departments.
Effective CAD system and call taking a discplined communications - and it worked great.
Also out west, several states (Colorado, Wyoming, Montana, etc) granted not LARGE population states - have statewide PSAPs for the highway patrol, fish and game, DOT etc.
For effective call taking, you do not need to know the town(s) if you have a proper CAD system in effect. Many northeast dispatchers will sit on the phone and chat and/or try to blow off calls so cops don't have to go somewhere. As long as you get a name, number, address and chief complaint - your good to go.
