About our Company

Our History

Mastor opened its doors as Mastor Telecom Equipment in early 1991. Selling primarily refurbished telecom equipment to installers, Mastor quickly grew in both size and reputation as an excellent source for quality refurbished equipment. Since early 2000, Mastor has provided clients in the St. Louis area and surrounding communities with excellent products and service. In 2008-2009, Mastor, working with Toshiba’s National Account Team, successfully sold, configured and shipped over 15,000 telephone systems for a large financial firm with offices all over the country. This sale was the largest single project in the history of Toshiba’s telecom division. Since the closure of Toshiba’s North American Telecom Division in 2016, and with the increasing popularity of VoIP technology and Unified Communications, we have refocused our product offerings. We have added additional products and services to our portfolio including NUSO Cloud PBX and SIP Trunking, Epygi VoIP Premise based systems, Security Cameras and NVR’s, and WiFi routers and wireless access points.
