*How we calculate minimum commitment. Headline per-user prices hide the real cost of trying a platform. Total cost of ownership is licence × seats × term, plus usage, add-ons, setup fees and any early-exit charges. Our "minimum commitment" figure is the floor of that: the entry plan's committed rate × the minimum seats the vendor will sell × the months you must commit to (one month at the month-to-month rate where there is no commitment; the licence price where it is sold per year). It deliberately excludes usage, add-ons and prerequisite licences, so your real first bill will be higher, but never lower than this. For Teams Phone the excluded prerequisites are the Microsoft 365 and Teams licences.

## Our review

8x8 is the platform to look at if you need unified communications and a full contact centre from one vendor: X2/X4 for UC, X6–X8 adding CCaaS, all under a platform-wide 99.999% SLA, with a strong Microsoft Teams story (Operator Connect in 50 countries) and UK data residency for recordings. It has a proper developer platform (Work Analytics REST API, real-time XCaaS events, CPaaS) but no first-party MCP.

8x8 has removed public pricing from most of its site, so expect quote-led, 12–36-month contracts; third-party UK figures put X2 at about £22 and X4 at £32 per user per month. Trustpilot is 2.8/5 on 624 reviews, with unreachable live support and drawn-out cancellations the recurring complaints.
