Customers Say: 8x8 Towers Above SIP Trunking Competitors

With its yearly revenue growing 27% and now approaching a half-billion dollars, 8x8 is far from the hosted PBX company it launched as 23 years ago. Today its product portfolio includes UCaaS, CCaaS (new bookings are up 62%), CPaaS, and SIP trunking — the latter introduced 10 years ago for the small, mid-market, and enterprise retail customers, and carrier (wholesale) customers.
Why SIP Trunking
Eastern Management Group research shows 80% of small, mid-market, and enterprise businesses use SIP trunking. Nearly 100% have SIP capability on the most recent new phone purchased. By 2027, 96% of all network traffic will be SIP. SIP trunking is more than big; it's the front door to 8x8's entire business.
SIP trunking is a $17 billion industry growing more than 7% annually. That's considerably faster growth than overall IT spending.
The explosive growth of SIP trunking is principally due to:
  • Incumbent carriers turning off the PSTN worldwide
  • SIP trunking rock-bottom prices
  • Remote work (e.g., work-from-home)
  • Due to COVID-19, accelerated adoption of cloud applications for enterprise productivity and process improvement, including mobile, messaging, video, and e-commerce]
  • UCaaS, CCaaS, CPaaS, growth
