• 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 logged during
failover but are available once the phone transitions to the alternate server.
• The Message Waiting Indicator is cleared, but voice mail may still be available if the voice
mail server to which calls are being sent is not in failover.
• Once the transition to a new server has occurred, advanced features like Call Park/Unpark,
Priority Call, or Automatic Callback may be available. Favorite features are not available
during failover but should be available after transition to the alternate server, depending on
your system's failover structure.
• Autodial numbers are available on the System Numbers screen during failover.
• If your phone operates under the latest software, Contacts can be accessed and changed
during failover to the alternate server. However, contact changes and new entries are limited
to no more than 25 and only one change to a specific contact is allowed. Also, contact
searches may be limited; in this case the message “Limited Search results available”
displays.
• Once the transition to a new server has occurred, if you are part of a corporate Directory or
database, access may be limited to local contacts only.
• You can access the Web applications during failover. However, any “click to dial” links will not
work until the phone transitions to the alternate server.
• Transitions back to the normal server will restore all original functionality.
