Extension 19 Answering

1.0/5 • Glassdoor rating


Extension 19 Answering Service was founded by Billie (Szabo) Stubblefield in 1974. Billie worked for Pacific Telephone Company in California, Chesapeake & Potomac in Maryland, Southwestern Bell Headquarters in St. Louis, Missouri; before transferring with Southwestern Bell to Houston, Texas in 1971. Three years later, she purchased a small answering service, beginning with just 7 clients. At that time, the hardware requirements were quite different as every client required a hard line extension to be connected directly to our office, hence our name Extension 19 Answering Service. As the number of clients grew, they were routed to a switchboard that was supported by a system of paper notes to collect, organize and relay the messages to the clients. Eventually, the advent of call forwarding and personal computers allowed Extension 19 to offer more overall flexibility and specialized service, specific to each client’s needs.
