Parameter Description
 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.
Graceful Busy Out
Timeout
[GracefulBusyOutTimeout]
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.
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.
Digital Out-Of-Service
Behavior
[DigitalOOSBehaviorForTr
unk_x]
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
per Trunk Group feature performed in the Trunk Group Settings table of
the Web interface.
 [-1] Not Configured = (Default) Use the settings of the
DigitalOOSBehavior parameter ("global" parameter that applies to all
trunks).
 [0] Default =

ISDN: Sends ISDN Service messages to indicate out-of-service
or in-service state for ISDN variants that support Service
messages. For ISDN variants that do not support Service
messages, the device sends an Alarm Indication Signal (AIS)
alarm.

CAS: Sends an Alarm Indication Signal (AIS) alarm.
 [1] Service = (Applicable only to T1 ISDN variants that support this
method) Sends ISDN Service messages indicating out-of-service or
in-service state.

Graceful out-of-service disabled: The device rejects new
incoming calls and immediately takes all channels (idle and busy)
out-of-service, by sending Service messages on the B-channels.

Graceful out-of-service enabled:
- Fully configured trunk (all channels): The device rejects new
incoming calls. If at least one busy channel exists during the
graceful period, the device immediately takes all idle channels
out-of-service, but sends out-of-service Service messages to the
B-channels only when all channels are idle.
- Partially configured trunk (only some channels configured): The
device rejects new incoming calls and places all channels out-of-
service only after the graceful period expires, by sending out-of-
