keep-alive OPTIONS messages.
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).
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.
Notes:
This parameter is applicable only if single device
registration is used (i.e., the parameter AuthenticationMode
is set to authentication per gateway).
Instead of configuring this parameter, the Authentication
table can be used (see Authentication on page 265).
Web/EMS: Password
[Password]
Defines the password for Basic/Digest authentication with a
ports.
The default is 'Default_Passwd'.
Note: Instead of configuring this parameter, the Authentication
table can be used (see Authentication on page 265).
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
[MutualAuthenticationMode]
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
[SIPChallengeCachingMode]
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
