Trio AB

Trio AB

Trio AB is telecommunications company which delivers Enterprise Telephony solutions to both operators (in which case the actual end users are offered a Hosted PBX solution) and directly to companies. While Trio was built during SS7/ISUP, it has been adapting to use VoIP in its newer products.

Note: Teligent acquired Trio in the early summer of 2006, and Trio ceased to exist as an independent entity.
