Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
configure voip > sip-
definition proxy-and-
registration > cnonce-4-
auth
[Cnonce]
'Challenge Caching Mode'
configure voip > sip-
definition proxy-and-
registration > challenge-
caching
[SIPChallengeCachingMode]
Enables local caching of SIP message authorization
challenges from Proxy servers.
The device sends the first request to the Proxy without
authorization. The Proxy sends a 401/407 response
with a challenge for credentials. The device saves
(caches) the response for further uses. The device
sends a new request 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. One of the benefits of the
feature is that it may reduce the number of SIP
messages transmitted through the network.
■ [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.
Note:
■ Challenge caching is used with all proxies and not
only with the active one.
■ For the Gateway application: The challenge can be
cached per endpoint or per Account.
■ For the SBC application: The challenge can be
cached per Account or per user whose credentials
are configured in the User Information table.

configure voip > sip-
definition proxy-and-

[IsRegisterNeeded]

■ [0] Disable = (Default) The device doesn't register
to Proxy/Registrar server.
■ [1] Enable = The device registers to
Proxy/Registrar server when the device is powered
up and at every user-defined interval (configured by
the parameter RegistrationTime).
Note:
■ The parameter is applicable only to the Gateway
application.
