Parameter Description
Web/EMS: Password
[Password]
The password used for Basic/Digest authentication with a
Proxy / Registrar server. A single password is used for all
device ports.
The default is 'Default_Passwd'.
Note: The Authentication table can be used instead (refer to
Authentication on page 212).
Web/EMS: Cnonce
[Cnonce]
Cnonce string used by the SIP server and client to provide
mutual authentication. (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 = Incoming requests that don't include AKA
authentication information are accepted (default).
 [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 resent
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 = 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
(default)
 [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.
Note: Challenge Caching is used with all proxies and not only
with the active one.
