A new report says Vocalocity and ShoreTel were the biggest gainers among the most significant players in the cloud Unified Communications as a Service (UCaaS) market last quarter.
The Synergy Research Group study says cloud UCaaS was up 22 percent year over year in Q2. Vocalocity's annual revenue growth during the same period was 45 percent, while ShoreTel's was 37 percent. iCore, RingCentral and 8x8 all had good years, each up between 18 and 22 percent.
Synergy says the market leaders accounted for more than half (54 percent) of total quarterly UCaaS revenue. 8x8 maintained its overall market share lead at 15 percent.
Public-cloud service offerings accounted for 52 percent of quarterly UCaaS revenue. Private cloud accounted for 30 percent, with the rest coming from premise + hybrid cloud and contact center SaaS. North America continues to account for more than 85 percent of worldwide revenue due to many other regions being underdeveloped.
"Looking beyond North America, I expect to see stronger growth in EMEA and APAC regions, which currently account for 49 [percent] of traditional UC and enterprise voice revenues but only 13 [percent] of UCaaS revenues," said Synergy Research Group's founder and Chief Analyst Jeremy Duke. "Operators such as Telstra and Orange are becoming increasingly active in these regions and UCaaS is becoming more accepted as a reliable, secure and economically compelling business communications solution."
