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.
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).
Defines the call transfer method used by the device. The parameter is
applicable to E1/T1 CAS call transfer if the TrunkTransferMode_x
parameter is set to 3 (CAS Normal) or 1 (CAS NFA).

[0] None = (Default) IP.

[1] Blind = PBX blind transfer:

E1/T1 CAS: When a SIP REFER message is received, the
device performs a blind transfer, by performing a CAS wink,
waiting a user-defined time (configured by the WaitForDialTime
parameter), dialing the Refer-To number, and then releasing the
call. The PBX performs the transfer internally.

[2] Semi Supervised = PBX semi-supervised transfer:

(within the user-defined interval set by the WaitForBusyTime
parameter),

E1/T1 CAS: The device performs a CAS wink, waits a user-
defined time (configured by the WaitForDialTime parameter),
and then dials the Refer-To number. If during the user-defined
interval set by the WaitForBusyTime parameter, no busy or
reorder tones are detected, the device completes the call
transfer by releasing the line. If during this interval, the device
detects these tones, the transfer operation is cancelled, the
device sends a SIP NOTIFY message with a failure reason (e.g.,
486 if a busy tone is detected), and then generates an additional
wink toward the CAS line to restore connection with the original
call.

[3] Supervised = PBX Supervised transfer:

E1/T1 CAS: The device performs a supervised transfer to the
PBX. The device performs a CAS wink, waits a user-defined
time (configured by the WaitForDialTime parameter), and then
dials the Refer-To number. The device completes the call
transfer by releasing the line only after detection of the
transferred party answer. To enable answer supervision, you
also need to do the following:
1) Enable voice detection (i.e., set the EnableVoiceDetection
parameter to 1).
2) Set the EnableDSPIPMDetectors parameter to 1.
3) Install the IPMDetector DSP option Feature License Key.
