networkn:Jase2985: there is none that provide them, spark offer them as an extra cost, or you could buy one yourself for a meager price of less than $100.
I never suggested they had to be free!
I do, however. The average end user can barely operate a cordless phone, let alone purchase, install and maintain a UPS. Should be part and parcel with wiring integration installs, or at a minimum another paid option during install.
