Parameter Description
■ [2] Accept Registered Users from Same
Source = Accepts requests only from registered
users whose source address is the same as that
registered with the device (during the REGISTER
message process). All other requests are
rejected. If the transport protocol is UDP, the
device verifies the IP address and port;
otherwise, it verifies only the IP address. The
verification is performed before any of the
device's call handling processes (i.e.,
Classification, Manipulation and Routing).
Note:
■ The parameter is applicable only to calls
belonging to User-type IP Groups.
■ The feature is not applicable to REGISTER
requests.
■ The option, Accept Registered Users from Same
Source [2] does not apply to registration
refreshes. These requests are accepted even if
the source address is different to that registered
with the device.
■ When the device rejects a call, it sends a SIP 500
"Server Internal Error" response to the user. In
addition, it reports the rejection (Dialog establish
failure - Classification failure) using the Intrusion
Detection System (IDS) feature (see Configuring
IDS Policies), by sending an SNMP trap.
■ If you configure the parameter to any value other
than default [-1], it overrides the corresponding
parameter in the SRDs table (SRD_
BlockUnRegUsersInterface) for the SRD
associated with the SIP Interface.
'Enable Un-Authenticated
Registrations'
enable-un-auth-registrs
[SIPInterface_
EnableUnAuthenticatedRegistrations]
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.
