Mediant 3000
Parameter Description

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
[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
Notes:
 The parameter is applicable only to the Gateway application.
 When set to ‘Not Configured’, the value of the parameter
SIPTransportType is used.
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 [%]
[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 after 3600 x
70% (i.e., 2520 sec).
Note: The parameter may be overridden if the parameter
RegistrationTimeThreshold is greater than 0.
Registration Retry Time
[RegistrationRetryTime]
Defines the time interval (in seconds) after which a registratio
n request is
re-sent if registration fails with a 4xx response or if there is no response
from the Proxy/Registrar server.
The default is 30 seconds. The range is 10 to 3600.
