MediaPack Series
Parameter Description
Default Release Cause
[DefaultReleaseCause]
Default Release Cause (to IP) for IP-to-Tel calls when the device initiates
a call release and an explicit matching cause for this release isn't found.
The default release cause is NO_ROUTE_TO_DESTINATION (3).
Other common values include NO_CIRCUIT_AVAILABLE (34),
DESTINATION_OUT_OF_ORDER (27), etc.
Notes:
The default release cause is described in the Q.931 notation and is
translated to corresponding SIP 40x or 50x values (e.g., 3 to SIP 404
and 34 to SIP 503).
For an explanation on mapping PSTN release causes to SIP
responses, refer to ‘Mapping PSTN Release Cause to SIP Response’
on page 336.
Delay After Reset [sec]
[GWAppDelayTime]
Defines the time interval (in seconds) that the device's operation is
delayed after a reset.
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' modifications by a
DHCP server.
Max Number of Active
Calls
[MaxActiveCalls]
Defines the maximum number of simultaneous active calls supported by
the device. If the maximum number of calls is reached, new calls are not
established.
The default value is the maximum available channels (no restriction on
the maximum number of calls). The valid range is 1 to maximum number
of channels.
Max Call Duration (min)
[MaxCallDuration]
Defines the maximum call duration (in minutes). If this time expires, both
sides of the call are released (IP and Tel).
The valid range is 0 to 35,791. The default is 0 (i.e., no limitation).
Enable LAN Watchdog
[EnableLanWatchDog]
Determines whether the LAN Watch-Dog feature is enabled.
[0] Disable = Disable LAN Watch-Dog (default).
[1] Enable = Enable LAN Watch-Dog.
When LAN Watch-Dog is enabled, the device's overall communication
integrity is checked periodically. If no communication for about 3 minutes
is detected, the device 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 device restarts to overcome internal fatal
communication error.
Notes:
Enable LAN Watchdog is relevant only if the Ethernet connection is full
duplex.
LAN Watchdog is not applicable to MP-118.
