Parameter Description
Registrar Transport Type
[RegistrarTransportType]
Determines the transport layer used for outgoing SIP dialogs
initiated by the device to the Registrar.
ƒ
[-1]
Not Configured (default)
ƒ
[0]
UDP
ƒ
[1]
TCP
ƒ
[2]
TLS
Note:
When set to ‘Not Configured’, the value of the parameter
SIPTransportType is used.
Registration Time
[RegistrationTime]
Defines the time interval (in seconds) for registering to a Proxy
server. The value is used in the Expires header. In addition, this
parameter 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 value is 180.
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 value is 50.
For example: If RegistrationTimeDivider is 70% and Registration
Expires time is 3600, the device re-sends its registration request
after 3600 x 70% = 2520 sec.
Note
: This parameter may be overriden if the parameter
RegistrationTimeThreshold is greater than 0 (refer to the
description of RegistrationTimeThreshold).
Registration Retry Time
[RegistrationRetryTime]
Defines the time interval (in seconds) after which a Registration
request is resent 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.
Registration 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 Expires
header minus the value of the parameter
RegistrationTimeThreshold.
The valid range is 0 to 2,000,000. The default value is 0.
Re-register On INVITE Failure
[RegisterOnInviteFailure]
Enables immediate re-registration if a failure response is received
for an INVITE request sent by the device.
ƒ
[0]
Disable = Disabled (default)
ƒ
[1]
Enable = Enabled
ReRegister On Connection
Failure
[ReRegisterOnConnectionFai
lure]
Enables the device to perform SIP Re-Registration upon TCP/TLS
connection failure.
ƒ
[0]
Disable (default).
ƒ
[1]
Enable.
