The premises-based segment of the UC industry is dead (though it limps along in aging PBX systems). Long live the UC cloud!
Premises-based UC had a great run, starting with the explosion of communications innovation in the wake of the 1968 Carterfone decision. It flourished through the ’80s and ’90s. In fact, many major companies are still acquiring premises-based solutions. Despite a major disruption in the 2000s with VoIP and UC, premises-based solutions will very likely keep offering lucrative revenue for at least another decade.
So how can something that is still bringing in revenue be dead?
