Technavio has forecast a 28 percent year-over-year growth for the global unified communications-as-a-service market from 2015 to 2019.
Faisal Ghaus, a vice president of Technavio, said Thursday the UCaaS market growth is driven by an increase in the use of smartphones for enterprise bring-your-own-device programs.
Ghaus projected Asia Pacific will be the biggest adopter of BYOD strategies by 2018.
The market research firm also sees the use of high-speed Internet connectivity and cloud-as-a-service platform as another factor that could drive the market over the next four years.
Key industry players include AT&T, Avaya, Cisco Systems, Hewlett Packard, Microsoft, Verizon, Google and Orange Business Services.
