Alternatives to Microsoft Teams

Microsoft Teams combines channels, guest access, unlimited message history, meetings, calls and screen sharing. Its free account needs no subscription, supports meetings and group calls lasting up to 60 minutes, and allows one-to-one calls without a time limit. Teams runs on web, Windows, macOS, Linux, iOS and Android, connects with Microsoft 365, and offers business plans with larger meetings, storage, recordings, transcripts, translation and support.

Choosing instead of Microsoft Teams

Readers may look elsewhere when their priority is a dedicated business phone system rather than broad collaboration. Teams’ free group calls and meetings stop after 60 minutes, while paid plans start at $4.00 user/month billed yearly; phone-focused options here instead emphasize business numbers, auto attendants, custom or advanced routing and voicemail transcription. Compare user allowances, device coverage, trial or free access, and whether you need hosted software or self-hosted deployment. Keep Teams in consideration when channels, Microsoft integrations, guest participation and meeting features outweigh specialized call handling.

Microsoft Teams, head to head
