  • How do I know if someone tried to call me (and I missed the call)?

  • How do I share data in a call?
    Select  (from the bottom of your call screen). Learn more about presenting.
  • I have a Lifesize Icon video system. How do I know if it's connected to Lifesize Cloud?
    From the Icon main screen, navigate to  > to view the status of the system. If it's connected, Ready shows for Communications > Lifesize Cloud Service.
  • I have a Lifesize 220 video system.  How do I know if it's connected to Lifesize Cloud?
    From your 220 system, navigate to Administrator Preferences > Communications to view the status of the system. If it's connected, Ready shows for Lifesize Cloud Service.
  • Can I reinstall the app? And does this affect my Cloud account?
    Install the app on all your devices at any time: upgrades occur automatically (including your video system, if it's connected to Lifesize Cloud). Incoming calls ring all devices (including your connected video system). Reinstalling the app will not affect your Cloud account.
  • How do I change my password?
    When you're logged in to the app, select Account > Change Password. Passwords must be between 8 and 32 characters in length and use standard ASCII characters. You can also change your profile: select Account > Manage Account and sign in to change your display name, email address, and password.
  • How do I know if I'm a Cloud account manager?
    If you sign in to the web console to manage other user accounts, you are an account manager. If you've signed up as an account manager by mistake, you won't see the rest of your company in the directory on your app.  Because there can be only one account manager for a Cloud group, you must sign up as a standard user instead. Contact your Lifesize representative for help signing up for a Cloud user account.
