One or more telephone system servers provide your phone with its connectivity, features, and functionality. If a disconnect or switch from one server to another occurs, your phone goes into Failover mode to keep it operating while alternate server resources are established. Depending on the server your phone is on, an icon may appear on the Top display line to notify you that failover is in effect.
Failover has different stages. For example, while your phone transitions to a new server it is in limbo and functionality may be limited. When the alternate server is active, your phone assumes the functionality available on that server, which may not be the same as your original server. When the original server is restored, your phone transitions back (failback) and functionality may again be limited during the transition. When your phone is back on the original server, normal functionality is restored. Failover and failback are automatic; you have no control over failure mode.
Keep in mind that during failover certain features may not be available and telephone functionality may be limited. Check the soft keys at the bottom of the display to determine the actions you can take during failover.
You can also press the Phone button to display possible action.
Important:
Do not log your telephone off during failover or until normal service is restored on your original telephone server. Logging off during failover, during transition to or from an alternate server, or while your phone is active on an alternate server may cause your phone to become inoperable.
The following conditions apply when your telephone is in Failover mode:
  • If you are on a call when failover occurs, the call will remain active. You cannot initiate new calls while your phone transitions to the alternate server.
  • Certain soft keys may not display and their related functions may be unavailable until transition to the alternate server is complete.
  • Call connection may take longer than usual.
  • During the transition to a new server, any active conference calls, call transfers, and held calls may be dropped. Incoming calls might not reach you and can go to voice mail.
  • Emergency calls might or might not work, depending on the stage of failover and the functionality available on the alternate server.
  • The Message Waiting Indicator is cleared, but voice mail might still be available if the voice mail server to which calls are being sent is not in failover.
  • Transitions back to the normal server will restore all original functionality.
