User's Manual
The above behavior is 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 Watchdog
feature 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.

FXO endpoints during Busy Out and Lock are inactive.

For additional optional behavior, see the LifeLineType
parameter.

Digital:

The Busy Out behavior depends on the PSTN protocol type.

The Busy Out condition is also applied per Trunk Group. This
occurs if there is no connectivity to the Serving IP Group of a
specific Trunk Group (configured in the Trunk Group Settings
table). In such a scenario, all the physical trunks of the Trunk
Group are set to the Busy Out condition. Each trunk uses the
out-of-service method according to the ISDN/CAS variant.

For configuring the method for taking trunks/channels out-of-
service, see the DigitalOOSBehaviorForTrunk_x parameter for
per trunk or the DigitalOOSBehavior parameter for all trunks.
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 parameter is applicable to the locking of Trunk Groups feature and
the Busy Out feature (see the EnableBusyOut parameter), where
trunks/channels are taken out-of-service.
The range is 0 to 3,600. The default is 0.
Note:
The parameter is applicable only to digital interfaces.
For configuring the method for taking trunks/channels out-of-service,
see the DigitalOOSBehaviorForTrunk_x parameter for per trunk or the
DigitalOOSBehavior parameter for all trunks
Defines the method for setting digital trunks to out-of-service state. The
parameter is defined per trunk. The parameter is applicable to the Busy
Out feature (see the EnableBusyOut parameter) and the Lock/Unlock
