I have petitioned for this type of thing for years in several markets and always have been told that it’s far too costly to ever get implemented on a large scale, so I have to ask; how big is your system?
Im glad to see someone somewhere has been able to accomplish this fully, as stated above I know the Verizon stuff is supposed to be that way but for one reason or another it has never worked out, I think mainly the cost involved in the initial buildup.
