Global VoIP Services Market will Reach $83 Billion

The global voice over IP (VoIP) service market totaled $73 billion in 2015 -- that's a 5 percent increase over the prior year, according to the latest worldwide market study by IHS. The growth was fueled by more companies shifting to cloud-based services and the adoption of Session Initiation Protocol (SIP).

VoIP communication services, including residential and business offerings, have become viable alternatives to legacy landline telephone services in most developed countries around the globe.

Although residential VoIP service remains a significant portion of VoIP services revenue, business services and the dynamic supplier landscape are driving new growth in the market.

VoIP Market Development Trends

The competitive landscape has become highly fragmented for VoIP business services, with an increasing number of PBX and Unified Communications (UC) vendors, enterprise agents and resellers expanding into the market along with traditional telecom service providers.

Additionally, hosted PBX and UC services are being pitched alongside SIP trunking as more multi-site businesses seek out hybrid solutions.

Continued strong worldwide growth is expected for the VoIP service market over the next five years, when it is forecast to reach $83 billion in 2020.


Other VoIP Market Study Highlights Include:

  • Residential VoIP services continued to make up the majority (62 percent) of VoIP service revenue in 2015.
  • There were 230 million residential VoIP subscribers worldwide in 2015, an increase of 3 percent from 2014.
  • Roughly 10 to 20 percent of new IP PBX lines sold are part of a managed service or outsourced contract depending on region; as a result, managed IP PBX services, including private cloud services, are expected to comprise the largest segment of business VoIP services over the next several years.
  • SIP trunking posted another year of solid growth in 2015, driven predominantly by activity in North America.
  • In 2015, UC-as-a-Service (UCaaS) revenue grew 6 percent over the prior year and seats were up 25 percent; the slower revenue growth is due to a highly competitive situation in North America that led to significant price cutting by many providers.
