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.


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 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 ISDN/CAS variant.

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.
Defines the method for setting digital trunks to Out-of-Service state per
trunk. To define the method for setting Out-Of-Service state for all
trunks, see the DigitalOOSBehavior parameter.

[-1] Not Configured = (Default) Use the settings of the
DigitalOOSBehavior parameter ("global" parameter that applies to
all trunks).

[0] Default =

ISDN: Use Service messages on supporting variants and use
alarm on non-supporting variants.

CAS: Use alarm.

[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).

The parameter is applicable only to digital interfaces.
