Parameter Description
Web: Re-registration Timing [%]
EMS: Time Divider
[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).
Note : This parameter may be overridden if the parameter
RegistrationTimeThreshold is greater than 0.
Web/EMS: 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
[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
[RegisterOnInviteFailure]
Enables immediate re-registration if no response is received for
an INVITE request sent by the device.

[0] Disable (default)

[1] Enable
When enabled, 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 RFC
3261 Timer B or due to the receipt of a 408 (Request
Timeout) response and the device has not received any
provisional response for the call (indicative of an outbound
proxy server failure).

The device terminates a call due to the receipt of a 408
(Request Timeout) response and the only provisional
response the device has received for the call is the 100
Trying provisional response (indicative of a home proxy
server failure).
Web: ReRegister On Connection
Failure
EMS: Re Register On Connection Enables the device to perform SIP re-registration upon
TCP/TLS connection failure.

[0] Disable (default)
