Parameter Description
application.

When set to ‘Not Configured’, the value of the parameter
SIPTransportType is used.
Web/EMS: Registration Time
CLI: registration-time
[RegistrationTime]
Defines the time interval (in seconds) for registering to a Proxy
server. The value is used in the SIP Expires header. This
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.
Web: Re-registration Timing [%]
EMS: Time Divider
CLI: re-registration-timing
[RegistrationTimeDivider]
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 this 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).
Notes :

This parameter may be overridden if the parameter
RegistrationTimeThreshold is greater than 0.
Web/EMS: Registration Retry Time
CLI: registration-retry-time
[RegistrationRetryTime]
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.
Web: Registration Time Threshold
EMS: Time Threshold
CLI: registration-time-thres
[RegistrationTimeThreshold]
Defines a threshold (in seconds) for re-registration timing. If
this 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.
Web: Re-register On INVITE Failure
EMS: Register On Invite Failure
CLI: reg-on-invite-fail
[RegisterOnInviteFailure]
Enables immediate re-registration if no response is received for
an INVITE request sent by the device.

[0] Disable (default)

[1] Enable = The device immediately expires its re-
registration timer and commences re-registration to the
same Proxy upon any of the following scenarios:

The response to an INVITE request is 407 (Proxy
Authentication Required) without an authentication
header included.

The remote SIP UA abandons a call before the device
has received any provisional response (indicative of an
outbound proxy server failure).

The remote SIP UA abandons a call and the only
provisional response the device has received for the
call is 100 Trying (indicative of a home proxy server
failure, i.e., the failure of a proxy in the route after the
outbound proxy).

The device terminates a call due to the expiration of
