User's Manual 69. Configuration Parameters Reference
Parameter Description
Unconditional >> 302
Others >> 302
If the device receives a Request-URI that includes a 'target' and
'cause' parameter, the 'target' is mapped to the Redirect phone
number and the 'cause' is mapped to the Redirect number reason.
[WaitForBusyTime]
Defines the time (in msec) that the device waits to detect busy and/or
reorder tones. This feature is used for semi-supervised PBX call
transfers (i.e., the LineTransferMode parameter is set to 2).
The valid value range is 0 to 20000 (i.e., 20 sec). The default is 2000
(i.e., 2 sec).
Line Transfer Mode

transfer-mode
[LineTransferMode]
Defines the call transfer method used by the device. The parameter
is applicable to FXO call transfer.
 [0] None = (Default) IP.
 [1] Blind = PBX blind transfer:

Analog (FXO): After receiving a SIP REFER message from
the IP side, the device (FXO) sends a hook-flash to the PBX,
dials the digits (that are received in the Refer-
To header), and
then immediately releases the line (i.e., on-hook). The PBX
performs the transfer internally.
 [2] Semi Supervised = PBX semi-supervised transfer:

Analog (FXO): After receiving a SIP REFER message from
the IP side, the device sends a hook-flash to the PBX, and
then dials the digits (that are received in the Refer-To
header). If no busy or reorder tones are detected (within the
user-defined interval set by the WaitForBusyTime
parameter), the device completes the call transfer by
releasing the line. If these tones are detected, the transfer is
cancelled, the device sends a SIP NOTIFY message with a
failure reason in the NOTIFY body (such as 486 if busy tone
detected), and generates an additional hook-flash toward the
FXO line to restore connection to the original call.
 [3] Supervised = PBX Supervised transfer:

Analog (FXO): After receiving a SIP REFER message from
the IP side, the device sends a hook-flash to the PBX, and
then dials the digits (that are received in the Refer-To
header). The device waits for connection of the transferred
call and then completes the call transfer by releasing the line.
If speech is not detected, the transfer is cancelled, the device
sends a SIP NOTIFY message with a failure reason in the
NOTIFY body (such as 486 if busy tone detected) and
generates an additional hook-flash toward the FXO line to
restore connection to the original call.
