Configuring Survivability; Faliover Or Failback Parameters - Avaya J129 Installing And Administering

Configuring survivability

Use the 46xxsettings.txt file to set survivability configuration parameters.
In IP Office, the autogenerated J100 settings.txt file contains the survivability configuration
parameter details.
By administering survivability configuration parameters using the 46xxsettings.txt file (or using
the default values if applicable), the SIP phones can quickly switch to an active controlling server
and experience minimal disruption.

features are not available.
