Business Voice & Data – formerly known as Independent Telephone Service was established in 1981 to provide telephone users an alternative interconnect provider in a newly deregulated telephone market. Analog voice technology has advanced at a rapid pace and has quickly merged with data applications to offer comprehensive and often times complex office communication possibilities. To better identify with the voice/data applications we have changed our name but not our commitment to provide the same personal service in the selection, application, and installation and servicing of your voice and data requirements.
