Parameter Description
Enable Busy Out
[EnableBusyOut]
No
[0] = ‘Busy out’ feature is not used (default).
Yes
[1] = ‘Busy out’ feature is enabled.
When Busy out is enabled, the MediaPack gateway performs a specific
behavior (e.g., plays a reorder tone when the phone is offhooked) due to one of
the following reasons:
 Physically disconnected from the network (i.e., Ethernet cable is
disconnected).
 The Ethernet cable is connected, but the gateway can't communicate with
any host. Note that LAN Watch-Dog must be activated
(EnableLANWatchDog = 1).
 The gateway can't communicate with the gatekeeper/proxy and no other
alternative exists to send the call.
Note: The FXSOOSBehavior parameter is used to control the behavior of the
FXS endpoints of the gateway when a Busy out or Graceful Lock occurs.
Note: FXO endpoints during Busy out and Lock are inactive.
Note: Refer to LifeLineType parameter for complementary optional behavior.
Default Release Cause
[DefaultReleaseCause]
Default Release Cause (to IP) for IPÆTel calls, used when the gateway initiates
a call release, and if an explicit matching cause for this release isn’t found, a
default release cause can be configured:
The default release cause is: NO_ROUTE_TO_DESTINATION (3).
Other common values are: NO_CIRCUIT_AVAILABLE (34),
DESTINATION_OUT_OF_ORDER (27), etc.
Note: The default release cause is described in the Q.931 notation, and is
translated to corresponding SIP 40x or 50x value. For example: 404 for 3, 503
for 34 and 502 for 27.
Delay After Reset [sec]
[GWAppDelayTime]
Defines the amount of time (in seconds) the gateway’s operation is delayed
after a reset cycle.
The valid range is 0 to 45. The default value is 7 seconds.
Note: This feature helps to overcome connection problems caused by some
LAN routers or IP configuration parameters change by a DHCP Server.
Max Number of Active Calls
[MaxActiveCalls]
Defines the maximum number of calls that the gateway can have active at the
same time. If the maximum number of calls is reached, new calls are not
established.
The default value is max available channels (no restriction on the maximum
number of calls). The valid range is 1 to max number of channels.
Max Call Duration (sec)
[MaxCallDuration]
Defines the maximum call duration in seconds. If this time expires, both sides of
the call are released (IP and Tel).
The valid range is 0 to 120. The default is 0 (no limitation).
Enable LAN Watchdog
[EnableLanWatchDog]
Disable [0] = Disable LAN Watch-Dog (default).
Enable
[1] = Enable LAN Watch-Dog.
When LAN Watch-Dog is enabled, the gateway's overall communication
integrity is checked periodically. If no communication for about 3 minutes is
detected, the gateway performs a self test.
- If the self test succeeds, the problem is logical link down (i.e. Ethernet cable
disconnected on the switch side), and the Busy out mechanism is activated if
enabled (EnableBusyOut = 1). LifeLine is activated if enabled.
- If the self test fails, the gateway restarts to overcome internal fatal
communication error.
Note: Enable LAN Watchdog is relevant only if the Ethernet connection is full
duplex.
Note: EnableLanWatchDog is not applicable to MP-118.
