Setting A Controller Via The User Interface - Avaya 9601 Administering

System Failover and Survivability
By administering survivability configuration parameters using the 46xxsettings file (or using the
default values if applicable), the SIP deskphones can quickly switch to an active controlling server
and experience minimal disruption. The failover/failback parameters are:
• CONTROLLER_SEARCH_INTERVAL - The time the phone waits to complete the
maintenance check for Monitored Controllers.
• DISCOVER_AVAYA_ENVIRONMENT - Determines whether the phone operates in a mode to
comply with the Avaya environment mode (provision of SIP/AST features and use of PPM for
download and backup/restore).
• ENABLE_REMOVE_PSTN_ACCESS_PREFIX - Enables the removal of the PSTN access
prefix from collected dial strings when the phone is communicating with a non-AST controller.
• FAILBACK_POLICY - Failback Policy.
• FAST_RESPONSE_TIMEOUT - Fast Response Timer.
• PSTN_VM_NUM - The number called when the phone is in failover and the Message button is
pressed.
• RECOVERY_REGISTER_WAIT - Reactive Monitoring Interval in seconds.
• REGISTERWAIT - Proactive Monitoring Interval in seconds.
• SIP_CONTROLLER_LIST - Configured Controller list. A comma-separated list of SIP URIs, a
hostname, or numeric IP address. If null, DHCP/DNS will provide the defaults.
• SIMULTANEOUS_REGISTRATIONS - The number of Session Managers with which the
deskphone will simultaneously register.
• SIPREGPROXYPOLICY - Registration Policy. The default value of this parameter is
simultaneous.

Setting a controller via the user interface
With SES 5.0+ survivability parameters can be provisioned in the SIP Phone Settings screens.
When setting survivability parameters, consider these points:
• The SIP proxy settings screen shows the SIP proxy server addresses (or DNS names) from the
list of configured controllers in descending priority from top to bottom. Note that duplicate
entries are removed from the list of configured controllers.
• An entry can be deleted by navigating to the entry and pressing the Delete softkey only if the
entry was created from this screen. You cannot delete an entry not created from this screen.
• If the New softkey is pressed, a new screen is shown which allows the user to enter the
parameter's values for server, transport type, and port. The server and port fields are initially
blank. The transport type is initially shown as TLS. Once any field is edited the Save softkey
appears. When the Save softkey is pressed a new entry is inserted into the list of configured
