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.

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:

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.

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:

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.

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.
