Qlingen vs Microsoft Teams Phone

Cloud PBX inside Microsoft 365 · Microsoft, United States

Teams Phone turns the Teams client into a phone on top of a per-user Teams Phone licence and a Microsoft or operator calling plan. Qlingen is a Microsoft Teams Phone alternative you run on your own cloud: a multi-tenant phone system on FreeSWITCH with call queues, callbacks, a browser softphone, a mobile app, an AI assistant and a full REST API — deployed and managed on a server in your own cloud account from one panel.
