'Max. Number of Registered Users'

[SIPInterface_MaxNumOfRegUsers]
Parameter
Mediant 1000 Gateway & E-SBC | User's Manual
Description
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.
■ [-1] Not Configured = (Default) The
corresponding parameter in the SRDs table
(SRD_EnableUnAuthenticatedRegistrations) of
the SRD associated with the SIP Interface is
applied.
■ [0] Disable = The device rejects REGISTER
requests from new users that were not
authenticated by a proxy server.
■ [1] Enable = 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.
■ If configured to Disable or Enable, the parameter
overrides the 'Enable Un-Authenticated
Registrations' parameter settings of the SRD (in
the SRDs table) that is associated with the SIP
Interface.
■ The parameter is applicable only to the SBC
application.
Defines the maximum number of users belonging to
the SIP Interface that can register with the device.
By default, no value is defined (i.e., the number of
allowed user registrations is unlimited).
Note: The parameter is applicable only to the SBC
application.
