8x8 vs. Vonage
Vonage lags. 8x8 leads.
Unlike Vonage, 8x8 delivers a unified, AI-powered platform that seamlessly connects UCaaS, CCaaS, and CPaaS—built with financially-backed uptime, certified Microsoft Teams integration, and award-winning admin experiences. Vonage’s lack of platform cohesion, lower SLA guarantees, and weak global coverage leave modern buyers wanting more.
- Unified UCaaS, CCaaS, and CPaaS platform.
- Security, global scalability, and long-term reliability.
- Simplified management and unified interaction data across your organization.
