page 338.
Defines the time interval (in seconds) for registering to a Proxy
server. The value is used in the SIP Expires header. The
parameter also defines the time interval between Keep-Alive
messages when the parameter EnableProxyKeepAlive is set to 2
(REGISTER).
Typically, the device registers every 3,600 sec (i.e., one hour).
The device resumes registration according to the parameter
RegistrationTimeDivider.
The valid range is 10 to 2,000,000. The default is 180.
Defines the re-registration timing (in percentage). The timing is a
percentage of the re-register timing set by the Registrar server.
The valid range is 50 to 100. The default is 50.
For example: If the parameter is set to 70% and the Registration
Expires time is 3600, the device re-sends its registration request
after 3600 x 70% (i.e., 2520 sec).
Note:

The parameter may be overridden if the parameter
RegistrationTimeThreshold is greater than 0.
Defines the time interval (in seconds) after which a registration
request is re-sent if registration fails with a 4xx response or if
there is no response from the Proxy/Registrar server.
The default is 30 seconds. The range is 10 to 3600.
Defines a threshold (in seconds) for re-registration timing. If the
parameter is greater than 0, but lower than the computed re-
registration timing (according to the parameter
RegistrationTimeDivider), the re-registration timing is set to the
following: timing set by the Registration server in the SIP Expires
header minus the value of the parameter
RegistrationTimeThreshold.
The valid range is 0 to 2,000,000. The default is 0.
Enables the device to perform SIP re-registration upon TCP/TLS
connection failure.

[0] Disable (default)

[1] Enable
Enables the device to perform explicit unregisters.

[0] Disable (default)

[1] Enable = The device sends an asterisk ("*") value in the
SIP Contact header, instructing the Registrar server to remove
all previous registration bindings. The device removes SIP
User Agent (UA) registration bindings in a Registrar, according
