when the device is powered up and at every user-defined
interval (configured by the parameter RegistrationTime).
Note: The device sends a REGISTER request for each
channel or for the entire device (according to the
AuthenticationMode parameter).
Web/EMS: Registrar Name
[RegistrarName]
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.
Web: Registrar IP Address
EMS: Registrar IP
[RegistrarIP]
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.
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 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.
