The IP address (or FQDN) and optionally, port number of the SIP Registrar
server. The IP address is in dotted-decimal notation, e.g.,
201.10.8.1:<5080>.
Notes:
If not specified, the REGISTER request is sent to the primary Proxy
server.
When a port number is specified, DNS NAPTR/SRV queries aren't
performed, even if DNSQueryType is set to 1 or 2.
If the RegistrarIP is set to an FQDN and is resolved to multiple
addresses, the device also provides real-time switching (hotswap mode)
between different Registrar IP addresses (IsProxyHotSwap is set to 1). If
the first Registrar doesn't respond to the REGISTER message, the same
REGISTER message is sent immediately to the next Proxy.
EnableProxyKeepAlive must be set to 0 for this logic to apply.
When a specific Transport Type is defined using
RegistrarTransportType, a DNS NAPTR query is not performed even if
DNSQueryType is set to 2.
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.
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).
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.
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.
Enables immediate re-registration if a failure response is received for an
INVITE request sent by the device.
[0] Disable = Disabled (default)
