Parameter
Mediant 1000 Gateway & E-SBC | User's Manual
Description
■ 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:
■ The parameter is applicable only to the Gateway
application.
■ 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. The 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 the 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: The parameter may be overridden if the
parameter RegistrationTimeThreshold is greater than 0.
