Configuring Survivability; Setting A Controller Via The User Interface - Avaya 9608 Administrator's Manual

Configuring survivability

Avaya recommends using the 46xxsettings file instead of SES/SM to set these parameters.
Avoid mixed sources for configuration of SIP servers.
By administering survivability configuration parameters using the 46xxsettings file (or using the
default values if applicable), the SIP deskphone(s) can quickly switch to an active controlling
server and experience minimal disruption. The failover/failback parameters, described in detail
in , 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.
●

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.
