3Com VCX V7111 VoIP Gateway User Guide
Description
No [0] = Busy out feature is not used (default).
Yes [1] = The V7111/FXS gateway plays a reorder tone when the phone is
offhooked and one of the following occurs:
(1) There is a network problem.
(2) Proxy servers do not respond and the internal routing table is not
configured.
No [0] = 'Busy out' feature is not used (default).
Yes [1] = 'Busy out' feature is enabled.
When Busy out is enabled, the gateway performs a specific behavior (for
example, plays a reorder tone when the phone is offhooked) due to one of
the following reasons:
Physically disconnected from the network (that is, 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.
The FXSOOSBehavior parameter is used to control the behavior of the FXS
endpoints of the gateway when a Busy out or Graceful Lock occurs.
FXO endpoints during Busy out and Lock are inactive.
Refer to LifeLineType parameter for complementary optional behavior.
Default Release Cause (to IP) for IP Tel calls, used when the gateway
initiates a call release, and if an explicit matching cause for this release is not
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.
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.
Defines the amount of time (in seconds) the gateways operation is delayed
after a reset cycle.
The valid range is 0 to 45. The default value is 7 seconds.
This feature helps to overcome connection problems caused by some LAN
routers or IP configuration parameters change by a DHCP Server.
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.
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).
