[RegistrationTimeDivider]
Version 5.8
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.
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 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).
