VoIP Over Mobile and Cellular Data Notice

Some mobile network operators may prohibit or restrict the use of VoIP functionality over their network and may also impose additional fees or other charges in connection with VoIP use. Cymbus will not be held liable for any charges, fees, or liability imposed by your carrier for use of VoIP over mobile and cellular data.

Emergency Calls Warning

The Cymbus app on iOS and Android is not intended or designed for placing or supporting calls to emergency service or calls for the purpose of obtaining assistance, help, or aid in the event of an emergency. The Cymbus app on iOS and Android will redirect emergency calls to the native cellular dialer when possible on a basis of best reasonable commercial efforts. However, this functionality is also dependent on the operating system of the mobile device, which is outside of our control and is subject to change at any time.

Sign In

Sign in with your email address and password. When prompted, give the app the following permissions:

Call Recording Permissions

If you're asked to give the Cymbus app permission to record a call, answer Yes even if you do not intend to record calls. It's really asking to access your microphone for making calls, not necessarily for recording.

Can't Sign In?

Click Forgot password? on the login screen, then enter your email address in the browser, and a password reset link will be sent to you. If you don’t receive that email, contact Customer Support.


We recommend keeping the Cymbus app running in the background so you continue to receive calls and messages. On a mobile device, the Cymbus app uses your cellular data to run in background if it is not connected to Wi-Fi.

Choose Sign out if you want the app to completely stop running. You will not receive any calls, messages, or notifications on this device, and will be required to log in next time you open the app. To sign out on a mobile device, select your initials in the top left corner, and tap Sign out at the bottom. On the desktop app, you can also Quit to stop the app from running. To quit or sign out, select Cymbus > Quit Cymbus or Sign out.
