8x8 certified to provide Microsoft Teams voice services in 57 countries
8x8 has received Microsoft certification for its session border controller (SBC) technology, enabling Microsoft Teams calls in 57 countries. The company is one of the few native cloud providers with certified SBC technology supporting both Direct Routing and Operator Connect. 8x8's direct carrier interconnections and licensed services aim to reduce costs and simplify global deployments.
How this was made

The 30-second read
Why it matters
Microsoft certification reduces perceived integration risk for enterprises and channel partners, potentially improving conversion for Teams calling deployments across multiple countries.
Market read
A concrete ecosystem validation (Microsoft certification) and expanded geographic scope (57 countries) can influence expectations for partner-led Teams calling adoption.
What to watch
The article lacks commercial details such as pricing, customer wins, or backlog, so traders may discount the announcement until there is evidence of traction.
Background
8x8 provides session border controller (SBC) technology and voice connectivity services that integrate with Microsoft Teams calling options.
Ticker impact
8x8 says Microsoft certified its session border controller technology, enabling Microsoft Teams calls in 57 countries via Direct Routing and Operator Connect.
Likely modest positive bias as the market prices improved distribution and reduced integration friction for Teams calling.
The article is a product certification and channel-enablement update, not a financial print. It is still a concrete go-to-market catalyst tied to Microsoft Teams connectivity and global coverage.
Market effects
Supports competitive positioning for UCaaS and cloud communications providers offering Teams calling without third-party gateways.
Highlights global (57-country) voice reach, which may shift enterprise procurement toward providers with certified Teams connectivity.
Reinforces Microsoft Teams ecosystem expansion for external calling, potentially affecting partner ecosystems and integration vendors worldwide.
Counterpoint
Certification does not guarantee near-term revenue impact; partners may already have alternative SBC/Direct Routing options and adoption could be slow.
