New fourth-quarter data from Synergy Research Group show that the UCaaS business suite now accounts for 8 percent of all managed and hosted business voice subscribers thanks to an annual growth rate of almost 30 percent.
By comparison, managed on-premise IP PBX subscriber numbers are steadily declining, while hosted business VoIP subscribers are growing, but at a rate of well below 10 percent per year.
In the fourth quarter, UCaaS business market leaders by revenue were 8×8, ShoreTel and RingCentral, who combined to take 36 percent of the market. By subscribers, Fonality, Vocalocity and Mitel join the market leaders. In the hosted business VoIP and managed on-premise IP PBX segments, there is no one clear market leader, with NTT, AT&T, Verizon, BT and Orange all having similar scale operations; following them are a long list of other traditional telcos.
“A fascinating battle is playing out between traditional telcos on the one hand and much smaller specialist operators and technology vendors on the other,” Synergy Research Group founder and chief analyst Jeremy Duke said. “Clearly UCaaS is going to carve out an ever-greater share of the managed and hosted business voice market and at the moment the telcos are being very slow to respond to the changing market.”
