User's Manual
by the parameter RegistrationTime).
Note: The device sends a REGISTER request for each channel or for
the entire device (according to the AuthenticationMode parameter).
Defines the Registrar domain name. If specified, the name is used as
the Request-URI in REGISTER messages. If it isn't specified (default),
the Registrar IP address, or Proxy name or IP address is used instead.
The valid range is up to 100 characters.
Defines the IP address (or FQDN) and port number (optional) of the
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 the parameter DNSQueryType is set to 1 or 2.

If the parameter 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 (the
parameter 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. To allow this mechanism, the
parameter EnableProxyKeepAlive must be set to 0.

When a specific transport type is defined using the parameter
RegistrarTransportType, a DNS NAPTR query is not performed even
if the parameter DNSQueryType is set to 2.
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.
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.
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.
