Version 5.8 279 September 2009
SIP User's Manual 6. Configuration Parameters Reference
Parameter Description
Web/EMS: Registrar Transport
Type
[RegistrarTransportType]
Determines the transport layer used for outgoing SIP dialogs
initiated by the device to the Registrar.
[-1] Not Configured (default)
[0] UDP
[1] TCP
[2] TLS
Note: When set to ‘Not Configured’, the value of the
parameter SIPTransportType is used.
Web/EMS: 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.
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 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).
Web/EMS: 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.
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 Expires
header minus the value of the parameter
RegistrationTimeThreshold.
The valid range is 0 to 2,000,000. The default value is 0.
Web: Re-register On INVITE Failure
EMS: Register On Invite Failure
[RegisterOnInviteFailure]
Enables immediate re-registration if a failure response is
received for an INVITE request sent by the device.
[0] Disable = Disabled (default)
[1] Enable = Enabled
Web: ReRegister On Connection
Failure
EMS: Re Register On Connection
Failure
[ReRegisterOnConnectionFailure]
Enables the device to perform SIP Re-Registration upon
TCP/TLS connection failure.
[0] Disable (default).
[1] Enable.
