Parameter Description
TLS Mutual
Authentication
[SIPInterface_TLSMutual
Authentication]
Enables TLS mutual authentication for the SIP Interface (when the device
acts as a server).
 [-1] Not Configured = (Default) The SIPSRequireClientCertificate
global parameter setting is applied.
 [0] Disable = Device does not request the client certificate for TLS
connection on the SIP Interface.
 [1] Enable = Device requires receipt and verification of the client
certificate to establish the TLS connection on the SIP Interface.
Block Unregistered Users
[SIPInterface_BlockUnRe
gUsers]
Enables the device to block (reject) incoming calls (INVITE requests) from
unregistered users belonging to the SIP Interface.
 [-1] Not Configured = (Default) The corresponding parameter in the
SRD table (SRD_BlockUnRegUsers) of the SRD that is associated
with the SIP Interface is applied.
 [0] No = Calls from unregistered users are allowed.
 [1] Yes = Calls from unregistered users are blocked.
Notes:
 When the device blocks a call, it sends a SIP 500 "Server Internal
Error" response to the remote end.
 The parameter applies to calls belonging to a User-type IP Group.
 If configured to Yes or No, the parameter overrides the 'Block
Unregistered Users' parameter of the associated SRD in the SRD
table.
Max. Number of
Registered Users
[SIPInterface_MaxNumO
fRegUsers]
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).
Enable Un-Authenticated
Registrations
[SIPInterface_EnableUn
AuthenticatedRegistratio
ns]
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.
 [-1] Not Configured = (Default) The corresponding parameter in the
SRD 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.
