Well, it was a Mainframe thing.... Care was AS400 I believe. The Telegence, hmmmm. Can't remember if that was the mainframe name.. Well, there was a lot of talk about migrating. They wanted Care to be the only system. Then Texas SBC took over and they had Telegence. Things got rather complicated. Too many billing systems. I think it was just too much effort I guess, if they still have more than one. Too many mergers really, SBC then the ATT.. got real nasty. Everything depends on the billing system. When these companies merge, it is a real nightmare. Its a very, big deal. Many of these other computer systems hang off and interface in the end with the billing system. You almost have to rewrite all your front end systems if you want to change a billing system. Plus imagine all the people that work on those billing systems! Do you let them all go or move to an entirely different system? Those are very big systems also. I can see how it could take years to migrate.
