'Enable Un-Authenticated
Registrations'
enable-un-auth-registrs
[SRD_
EnableUnAuthenticatedRegistrations]
Parameter
Mediant 1000 Gateway & E-SBC | User's Manual
Description
■ When the corresponding parameter in the SIP
Interfaces table (SIPInterface_
BlockUnRegUsers) is configured to any value
other than default [-1] for a SIP Interface that is
associated with the SRD, the parameter in the
SRDs table is ignored for calls belonging to the
SIP Interface.
■ The parameter is applicable only to the SBC
application.
Enables the device to accept REGISTER requests
and register them in its registration database from
new users that have not been authenticated by a
proxy/registrar server (due to proxy down) and thus,
re-routed to a User-type IP Group.
In normal operation scenarios in which the proxy
server is available, the device forwards the
REGISTER request to the proxy and if authenticated
by the proxy (i.e., device receives a success
response), the device adds the user to its registration
database. The routing to the proxy is according to the
SBC IP-to-IP Routing table where the destination is
the proxy's IP Group. However, when the proxy is
unavailable (e.g., due to network connectivity loss),
the device can accept REGISTER requests from
new users if a matching alternative routing rule exists
in the SBC IP-to-IP Routing table where the
destination is the user's User-type IP Group (i.e., call
survivability scenarios) and if the parameter is
enabled.
■ [0] Disable = The device rejects REGISTER
requests from new users that were not
authenticated by a proxy server.
■ [1] Enable = (Default) The device accepts
REGISTER requests from new users even if they
were not authenticated by a proxy server, and
registers the user in its registration database.
Note:
■ Regardless of the parameter, the device always
accepts registration refreshes from users that are
already registered in its database.
■ For a SIP Interface that is associated with the
SRD, if the corresponding parameter in the SIP
Interfaces table (SIPInterface_
EnableUnAuthenticatedRegistrations) is
configured to Disable or Enable, the parameter in
the SRD is ignored for calls belonging to the SIP
Interface.
■ The parameter is applicable only to the SBC
application.
