Mediant 2000 SIP

Table 6-3: SIP Configuration Parameters (continues on pages 100 to 110)

ini File Field Name	Valid Range and Description
Web Parameter Name*
ProxyRedundancyMode	0 = Parking mode: gateway continues working with the last active Proxy until the next
[Redundancy Mode]	failure. (default)
	1 = Homing mode: gateway always tries to work with the primary Proxy server
	(switches back to the primary Proxy whenever it is available).
	Note: To use ProxyRedundancyMode, enable Keep-alive with Proxy option
	(EnableProxyKeepAlive=1).
IsTrustedProxy	This parameter isn’t applicable and must always be set to 1.
[Is Proxy Trusted]	The parameter ‘AssertedIdMode’ should be used instead.
IsFallbackUsed	0 = Gateway fallback is not used (default).
[Enable Fallback to	1 = Internal Telephone to IP Routing table is used when Proxy servers are not
Routing Table]	available.
	When the gateway falls back to the internal Telephone to IP Routing table, the gateway
	continues scanning for a Proxy. When the gateway finds an active Proxy, it switches
	from internal routing back to Proxy routing.
	Note: To enable the redundant Proxies mechanism set ‘EnableProxyKeepAlive’ to 1.
UserName	Username used for Registration and for Basic/Digest authentication process with Proxy
[User Name]	/ Registrar.
	Parameter doesn’t have a default value (empty string).
Password	Password used for Basic/Digest authentication process with Proxy / Registrar.
[Password]	The default is “Default_Passwd”.
Cnonce	String used by the SIP Server and client to provide mutual authentication (free format,
[Cnonce]	i.e., “Cnonce = 0a4f113b”).
	The default is “Default_Cnonce”.
IsRegisterNeeded	0 = Gateway does not register to Proxy/Registrar (default)
[Enable Registration]	1 = Gateway registers to Proxy/Registrar at power up
RegistrarIP	IP address of Registrar server (optional). If not specified, the gateway registers to Proxy
[Registrar IP Address]	server.
RegistrarName	Registrar Domain Name.
[Registrar Name]	If specified, the name is used as Request-URI in Register messages.
	If isn’t specified (default), the Registrar IP address or Proxy name or Proxy IP
	address is used instead.
GWRegistrationName	Defines the user name that is used in From and To headers of Register messages.
[Gateway Registration Name]	If ‘GWRegistrationName’ isn’t specified (default), the ’Username’ parameter is used
	instead.
RegistrationTime	Registration expired timeout (seconds). The value is used in "Expires = " header.
[Registration Time]	Typically a value of 3600 is assigned, for one hour registration.
	The gateway resumes registration when half the defined timeout period expires.
RegistrationTimeDivider	Defines the re-registration timing (in percentage). The timing is a percentage of the re-
[Re-registration Timing (%)]	register timing set by the Registration server.
	The valid range is 50 to 100. The default value is 50.
	For example: If ‘RegistrationTimeDivider = 70’ (%) and Registration Expires time =
	3600, the gateway resends its registration request after 3600 x 70% = 2520 sec.
RegistrationRetryTime	Defines the time period (in seconds) after which a Registration request is resent if
[Registration Retry Time]	registration fails with 4xx, or there is no response from the Proxy/Registrar.The default
	is 30 seconds. The range is 10 to 3600.
PrackMode	PRACK mechanism mode for 1XX reliable responses:
[PRACK Mode]	0 = Disabled
	1 = Supported (default)
	2 = Required
	Note 1: The Supported and Required headers contain the “100rel” parameter.
	Note 2: The Mediant 2000 sends PRACK message if 180/183 response is received
	with “100rel” in the Supported or the Required headers.
