Version 7.0 331 Mediant 3000
User's Manual 18. Control Network
Parameter Description
Interface that is associated with the SRD, the parameter in the SRD
table is ignored for calls belonging to the SIP Interface.
Enable Un-Authenticated
Registrations
[SRD_EnableUnAuthenti
catedRegistrations]
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-
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.
Notes:
 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 Interface table
(SIPInterface_EnableUnAuthenticatedRegistrations) is configured to
Disable or Enable, the parameter in the SRD is ignored for calls
belonging to the SIP Interface.
Used By Routing Server
[SIPInterface_UsedByRo
utingServer]
Enables the SRD to be used by a third-party routing server for call routing
decisions.
 [0] Not Used (default)
 [1] Used
For more information on the third-party routing server feature, see
''Centralized Third-Party Routing Server'' on page 284.
