Cause For NC
[SITQ850CauseForNC]
Determines the Q.850 cause value specified in the SIP Reason header
that is included in a 4xx response when SIT-NC (No Circuit Found
Special Information Tone) is detected from the PSTN for IP-to-Tel calls.
The valid range is 0 to 127. The default value is 34.
Note: When not configured (i.e., default), the SITQ850Cause parameter

Cause For IC
[SITQ850CauseForIC]
Determines the Q.850 cause value specified in the SIP Reason header
that is included in a 4xx response when SIT-IC (Operator Intercept

The valid range is 0 to 127. The default value is -1 (not configured).
Note: When not configured (i.e., default), the SITQ850Cause parameter
is used.
Web/EMS: SIT Q850
Cause For VC
[SITQ850CauseForVC]
Determines the Q.850 cause value specified in the SIP Reason header
that is included in a 4xx response when SIT-VC (Vacant Circuit - non-
registered number Special Information Tone) is detected from the PSTN
for IP-to-Tel calls.
The valid range is 0 to 127. The default value is -1 (not configured).
Note: When not configured (i.e., default), the SITQ850Cause parameter
is used.

Out
[EnableBusyOut]
Determines whether the Busy Out feature is enabled.
[0] Disable = 'Busy out' feature is not used (default).
[1] Enable = 'Busy out' feature is enabled.
When Busy Out is enabled and certain scenarios exist, the device
performs the following:
For analog interfaces: A reorder tone (configured by the parameter
FXSOOSBehavior) is played when the phone is off-hooked.
These behaviors are performed upon one of the following scenarios:
Physically disconnected from the network (i.e., Ethernet cable is
disconnected).
The Ethernet cable is connected, but the device can't communicate
with any host. Note that LAN Watch-Dog must be activated (the
parameter EnableLANWatchDog set to 1).
The device can't communicate with the proxy (according to the Proxy
Keep-Alive mechanism) and no other alternative route exists to send
the call.
The IP Connectivity mechanism is enabled (using the parameter
AltRoutingTel2IPEnable) and there is no connectivity to any
destination IP address.
