Instead of Microsoft Teams

Microsoft Teams alternatives

Microsoft Teams combines channels, guest access, unlimited message history, meetings, calls, and screen sharing. A free account needs no subscription and supports group meetings and calls for up to 60 minutes, while one-to-one calls have no time limit. It runs on web, desktop, and mobile platforms, connects with Microsoft 365 apps and other integrations, and its business plans add features such as longer meetings, more storage, recordings, and support.

Teams may be more collaboration suite than a phone-focused team needs, and its free group calls and meetings have a time limit. Paid business plans start at $4.00 user/month billed yearly; other listed options cost more. The alternatives below emphasize business calling, routing, and contact-center work, with differences in user allowances, platforms, and deployment. Compare the call features and operating model you need with Teams’ channels, integrations, and meeting tools. A dedicated phone system may fit calling needs better; Teams may suit a team that values its broader collaboration tools.
