Frequently Asked Questions — 8x8 vs RingCentral
Is 8x8 or RingCentral better for business UCaaS?+
8x8 is generally better for businesses wanting UCaaS and CCaaS unified on a single XCaaS platform — particularly with global (55-country) PSTN requirements. RingCentral is generally better for enterprises needing the broadest third-party integration ecosystem (300+ apps), CPaaS developer APIs, and a more mature contact center partnership model. Both offer 99.999% SLA.
What is 8x8 XCaaS and how does it compare to RingCentral?+
8x8 XCaaS (eXperience Communications as a Service) is 8x8's unified platform that combines UCaaS (phone, video, messaging) and CCaaS (contact center) on a single license and platform. RingCentral offers UCaaS via its core platform and CCaaS via RingCX as a separate add-on. For businesses wanting full convergence, 8x8's single-platform approach can simplify licensing and administration.
Does 8x8 or RingCentral have better global coverage?+
8x8 offers PSTN in 55+ countries with local number availability, which is broader than RingCentral's 40+ country PSTN coverage. For organizations with teams in Southeast Asia, Middle East, or less-common markets, 8x8's coverage may be an advantage. Both cover major markets (US, UK, EU, AU) equivalently.
