Version 7.2 1059 Mediant 500L Gateway & E-SBC
User's Manual 69. Configuration Parameters Reference
Parameter Description
name
[RegistrarName]
address is used instead.
The valid range is up to 100 characters.
Note: The parameter is applicable only to the Gateway
application.
Registrar IP Address
configure voip > sip-definition
proxy-and-registration > ip-addrr-
rgstrr
[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>.
Note:
 The parameter is applicable only to the Gateway application.
 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.
Registrar Transport Type
configure voip > sip-definition
settings > registrar-transport
[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:
 The parameter is applicable only to the Gateway application.
 When set to ‘Not Configured’, the value of the parameter
SIPTransportType is used.
Registration Time
configure voip > sip-definition
proxy-and-registration >
registration-time
[RegistrationTime]
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.
Re-registration Timing [%]
configure voip > sip-definition
settings > re-registration-timing
[RegistrationTimeDivider]
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
