Parameter Description
Web/EMS: Enable Busy
Out
CLI: busy-out
[EnableBusyOut]
Enables the Busy Out feature.
[0] Disable (Default)
[1] Enable
When Busy Out is enabled and certain scenarios exist, the device does
the following:
Analog: The FXS port behaves according to the settings of the
FXSOOSBehavior parameter such as playing a reorder tone when the
phone is off-hooked, or changing the line polarity.
Digital: All E1/T1 trunks are automatically taken out of service by taking
down the D-Channel or by sending a Service Out message for T1 PRI
trunks supporting these messages (NI-2, 4/5-ESS, DMS-100, and
Meridian).
These behaviors are done upon one of the following scenarios:
The device is physically disconnected from the network (i.e.,
Ethernet cable is disconnected).
The Ethernet cable is connected, but the device is unable to
communicate with any host. For this scenario, the LAN Watch-Dog
must be activated (i.e., set the EnableLANWatchDog parameter to
1).
The device can't communicate with the proxy (according to the Proxy
Keep-Alive mechanism) and no other alternative route exists to send
the call.
The IP Connectivity mechanism is enabled (using the
AltRoutingTel2IPEnable parameter) and there is no connectivity to
any destination IP address.
Notes:
Analog: The FXSOOSBehavior parameter determines the behavior
of the FXS endpoints when a Busy Out or Graceful Lock occurs.
Analog: FXO endpoints during Busy Out and Lock are inactive.
Analog: See the LifeLineType parameter for complementary optional
behavior.
Digital: The Busy Out behavior depends on the PSTN protocol type.
Digital: The Busy-Out condition can also be applied to a specific
Trunk Group. If there is no connectivity to the Serving IP Group of a
specific Trunk Group (defined in the Hunt Group Settings table), all
physical trunks pertaining to that Trunk Group are set to the Busy-
Out condition. Each trunk uses the proper Out-Of-Service method
according to the selected ISDN/CAS variant.
Digital: To configure the method for setting digital trunks to Out-Of-
Service, use the DigitalOOSBehavior parameter.
Web/EMS: Graceful Busy
Out Timeout [sec]
CLI: graceful-bsy-out-t-out
[GracefulBusyOutTimeo
ut]
Defines the timeout interval (in seconds) for Out-of-Service graceful
shutdown mode for busy trunks (per trunk) if communication fails with a
Proxy server (or Proxy Set). In such a scenario, the device rejects new
calls from the PSTN (Serving Trunk Group), but maintains currently
active calls for this user-defined timeout. Once this timeout elapses, the
device terminates currently active calls and takes the trunk out of
service (sending the PSTN busy-out signal). Trunks on which no calls
are active are immediately taken out of service regardless of the
timeout.
The range is 0 to 3,600. The default is 0.
Note: This parameter is applicable only to digital interfaces.
