UC-One is an intuitive business communications app for business calling, messaging and meetings. Users can participate in 1-1 and group chat and make business calls using their business identity from their service provider’s BroadWorks communications platform, even when calling from their personal smartphone.

UC-One uses BroadSoft Meet, a virtual meeting room app that provides an integrated and exceptional HD video and screen sharing meeting experience with other UC-One users and external guests.

UC-One integrates with common cloud business apps like G-Suite and Office 365, to streamline your work and make it easy to access those apps, while you’re communicating in UC-One.

Key Features Include:
• Business Messaging and Calling
• Corporate Directories
• Call History
• Access Voicemail
• Manage Basic Call Settings
• Business App Integrations

Note: UC-One will only work for BroadWorks subscribers on a UC-One enabled service provider. Please contact your service provider for details.

Drops calls

Worst phone app I’ve ever used. Drops calls almost every time. When you answer the phone it doesn’t start the conversation. Every time I have to ask hello, multiple times. The functionality of the app is all over the place. The welcome screen is the messages section which is useless in most cases. The app constantly logs you out. Prepared for missed calls. The “do not disturb” function is useless. It doesn’t work. It still alerts you for phone calls and messages. This is the most frustrating calling app I’ve ever used.

This app is terrible. I have had to uninstall and reinstall this app countless times to try to get it to work properly. Even then, calls get dropped and the app randomly logs me out multiple times every day. I also get errors constantly while logged in. My calls are supposed to ring to a handset on my desk and through the app on my cell (so I can work throughout the office and still answer calls). However, this function only sometimes works.

Do not get this app.

Do not download this app. If I could give this a 0 I would. Worst app ever. Doesn’t abide by any of its own app rules and settings or my phone settings. Not helpful at all. Tried to require me to use a password to call out of my own phone. Nightmare.
