Mediant 4000 SBC | User's Manual
Parameter Description
■ [1] Enable = If the device receives a SIP response for a
failed INVITE message and the response code is
configured in the global parameter, Accoun-
tInviteFailureTriggerCodes, the device re-registers the
Account according to the settings of the Proxy Set
associated with the Account's Serving IP Group. Note
that if the Proxy Set’s 'Proxy Hot Swap' parameter is
configured to Enable and the 'Proxy Keep-Alive'
parameter to Using OPTIONS or Using REGISTER,
then the registrar at which the INVITE failed is tried last
in the list of servers in the Proxy Set.
'Reg Event Package
Subscription'
reg-event-package-
subscription
[Account_
RegEventPackageSubscription]
Enables the device to subscribe to the registration event
package service (as defined in RFC 3680) with the registrar
server (Serving IP Group) to which the Account is
successfully registered and binded, when the Registrar
Stickiness feature is enabled. The service allows the
device to receive notifications of the Accounts registration
state change with the registrar.
The device subscribes to the service by sending a
SUBSCRIBE message containing the Event header with
the value "reg" (Event: reg). Whenever a change occurs in
the registration binding state, the registrar notifies the
device by sending a SIP NOTIFY message.
■ [0] Disable (default)
■ [1] Enable
Note: The parameter is applicable only if you have enabled
the Registrar Stickiness feature (in this table):
■ 'Register' parameter to Regular or GIN.
■ 'Registrar Stickiness' parameter to Enable.
'Register by Served IP Group
Status'
reg-by-served-ipg-
status
[Account_RegByServedIPG]
Defines the device's handling of Account registration based
on the connectivity status of the Served IP Group.
■ [0] Register Always = (Default) Account registration
by the device does not depend on the connectivity
status of the Served IP Group. The device sends
registration requests to the Serving IP Group even if the
Served IP Group is offline.
■ [1] Register Only if Online = The device performs
Account registration depending on the connectivity
status of the Served IP Group. It sends a registration
request to the Serving IP Group only if the Served IP
Group is online. If the Served IP Group was registered,
but then goes offline, the device unregisters it. If it
becomes online again, the device re-registers it. This
option is applicable only to Accounts where registration
is initiated by the device (i.e., the 'Register' parameter
is configured to any value other than No).
