Microsoft Teams

Teams Phone is less a competitor in the UCaaS market than the gravity well the whole market now orbits. For a company standardized on Microsoft 365, the license economics are compelling: Teams Phone is a modest add on, included outright in E5, and users never leave the application they already spend their day in. Identity, security, and administration stay inside the Microsoft estate, which IT departments value highly. The honest tradeoffs: calling features are serviceable rather than category leading, sophisticated routing and reception scenarios take more work than on dedicated platforms, and making Teams a reliable business phone system requires carrier decisions, calling plans, Operator Connect, or direct routing, that Microsoft leaves to the buyer. Support for voice problems runs through general Microsoft channels unless a partner fills the gap, which is why a large share of successful Teams voice deployments involve a voice enablement specialist. The right comparison is rarely Teams versus nothing; it is Teams plus enablement versus a dedicated platform, priced honestly on both sides.
