[SRD_
EnableUnAuthenticatedRegistrations]
Parameter
Mediant 800 Gateway & E-SBC | User's Manual
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
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
IDS Policies), by sending an SNMP trap.
■ 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.
