Chapter 13: Limited access during failover
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, a
Failover 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 its
functionality may be limited. Then 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 softkeys at the bottom of the display to determine the
actions you can take during failover; also try the
Phone
button to display the Home screen or
Avaya Menu
button for possible actions.
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:
• Messages like “Acquiring service," “Link recovery,” “Limited phone service,” and “Calls
may be lost ” inform you of a failover situation.
• If you are on a call when failover occurs, that call will remain active. You cannot initiate
new calls while your phone transitions to the alternate server.
• Certain softkeys 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 will be dropped. Incoming calls may not reach you; such calls may go to
voice mail.
• Emergency calls may or may not work, depending on the stage of failover and the
functionality available on the alternate server.
• Once the transition to a new server has occurred, bridged call appearances are
available. Despite a "Log Bridged Calls" option setting of yes, bridged calls are not
