User's Manual 53. Configuration Parameters Reference
Parameter Description
The OPTIONS Request-URI host part contains either the device's IP
address or a string defined by the parameter SIPGatewayName. The
device uses the OPTIONS request as a keep-alive message to its
primary and redundant Proxies (i.e., the parameter
EnableProxyKeepAlive is set to 1).
Note: This parameter is applicable only to the Gateway / IP-to-IP
application.
Web/EMS: User Name
[UserName]
Defines the user name used for registration and Basic/Digest
authentication with a Proxy/Registrar server.
The default is an empty string.
Note:

This parameter is applicable only to the Gateway / IP-to-IP
application.

This parameter is applicable only if single device registration is used
(i.e., the parameter AuthenticationMode is set to authentication per
gateway).
Web/EMS: Password
[Password]
Defines the password for Basic/Digest authentication with a
Proxy/Registrar server. A single password is used for all device ports.
The default is 'Default_Passwd'.
Web/EMS: Cnonce
[Cnonce]
Defines the Cnonce string used by the SIP server and client to provide
mutual authentication.
The value is free format, i.e., 'Cnonce = 0a4f113b'. The default is
'Default_Cnonce'.
Web/EMS: Mutual
Authentication Mode
[MutualAuthenticationM
ode]
Determines the device's mode of operation when Authentication and
Key Agreement (AKA) Digest Authentication is used.

[0] Optional = (Default) Incoming requests that don't include AKA
authentication information are accepted.

[1] Mandatory = Incoming requests that don't include AKA
authentication information are rejected.
Web/EMS: Challenge
Caching Mode
[SIPChallengeCachingM
ode]
Determines the mode for Challenge Caching, which reduces the
number of SIP messages transmitted through the network. The first
request to the Proxy is sent without authorization. The Proxy sends a
401/407 response with a challenge. This response is saved for further
uses. A new request is re-sent with the appropriate credentials.
Subsequent requests to the Proxy are automatically sent with
credentials (calculated from the saved challenge). If the Proxy doesn't
accept the new request and sends another challenge, the old challenge
is replaced with the new one.

[0] None = (Default) Challenges are not cached. Every new request
is sent without preliminary authorization. If the request is challenged,
a new request with authorization data is sent.

[1] INVITE Only = Challenges issued for INVITE requests are
cached. This prevents a mixture of REGISTER and INVITE
authorizations.

[2] Full = Caches all challenges from the proxies.
Notes:

This parameter is applicable only to the Gateway IP-to-IP
application.

Challenge Caching is used with all proxies and not only with the
