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.
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.
Determines the method for setting digital trunks to Out-of-Service state
per trunk.

[-1] Not Configured = (Default) Use the settings of the
DigitalOOSBehavior parameter for per device.

[0] Default = Uses default behavior for each trunk (see note below).

[1] Service = Sends ISDN In or Out of Service (only for ISDN
protocols that support Service message).

[2] D-Channel = Takes D-Channel down or up (ISDN only).

[3] Alarm = Sends or clears PSTN AIS Alarm (ISDN and CAS).

[4] Block = Blocks trunk (CAS only).
Notes:

This parameter is applicable only to digital interfaces.

This parameter is applicable only if the EnableBusyOut parameter
is set to 1 (Enable).

The default behavior (value 0) is as follows:

ISDN: Use Service messages on supporting variants and use
Alarm on non-supporting variants.

CAS: Use Alarm.

When updating this parameter value at run-time, you must stop the
trunk and then restart it for the update to take effect.

To determine the method for setting Out-Of-Service state for all
trunks (i.e., per device), use the DigitalOOSBehavior parameter.

The x in the ini file parameter name denotes the trunk number,
where 0 is Trunk 1.
Determines the method for setting digital trunks to Out-of-Service
state. This configuration applies to all the device's trunks. For a
description of this parameter's options, see the
DigitalOOSBehaviorForTrunk_x parameter.
Notes:

This parameter is applicable only to digital interfaces.

To configure the method for setting Out-of-Service state per trunk,
use the DigitalOOSBehaviorForTrunk_x parameter.
