This is supposed to be an app for businesses. What a joke ### 1/5 — MS login broken *2025-01-09, version 5.3.19* Cannot use Microsoft Login on this version, just get an error MSALErrorDo-main error -50000 ### 3/5 — Good but lacks features you you expect *2024-01-20, version 5.3.1* The interface is very clean and ties in well with he desktop app but the description mentions voice and video but unless I’m missing something the product has no video support currently. ### 5/5 — Solid and reliable and feature-rich *2023-10-03, version 5.1.8* As a user of CallSwitch Communicator 6 I approached CallSwitch One with some caution as I didn’t know if it could better an already solid and feature-rich platform. But it has. CallSwitch One offers a neat and simple interface whilst offering all the features a user demands. I can flexibly change my outbound CLI and work across multiple devices with features such as presence and chat as standard. SSO (Single Sign On) makes the set-up and configuration easy if you’re a Microsoft or Google user. ## Frequently asked questions about CallSwitch One ### What is CallSwitch One?
