Rainbow Office Phone

With Rainbow Office Softphone, you can manage your phone system directly from your preferred device and operating system (OS) to take calls, listen to voice messages, and send or receive faxes from anywhere. Easily separate your business and personal communications on the same device, and all without using any carrier minutes.

You can also access the same capabilities on the Rainbow Office App, which is our unified app that lets you access team messaging, phone calling, and video meetings all from one intuitive interface.

Key Features
