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.

receive a response, the phone assumes that AST
features are not available.

features are not available.
ENABLE_REMOVE_PSTN_ACC

Allows phone to perform digit manipulation during
failure scenarios. This parameter allows removal of

0: PSTN access prefix is retained in the outgoing
number

number.
