Web/EMS: Line Transfer Mode
[LineTransferMode]
Determines the call transfer method used by the device.
[0] None = IP (default).
[1] Blind = PBX blind transfer. After receiving a REFER
message from the IP side, the FXO sends a hook-flash to
the PBX, dials the digits (that are received in the Refer-To
header), and then immediately drops the line (on-hook). The
PBX performs the transfer internally.
[2] Semi Supervised = PBX Semi-Supervised transfer. After
receiving a REFER message from the IP side, the FXO
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 approximately 2 seconds), the
device completes the call transfer by releasing the line;
otherwise, 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 towards the FXO line to restore
connection to the original call.
[3] Supervised = PBX Supervised transfer. After receiving a
REFER message from the IP side, the FXO sends a hook-
flash to the PBX, and then dials the digits (that are received
in the Refer-To header). The FXO waits for connection of the
transfer call and if speech is detected (e.g., "hello") within
approximately 2 seconds, the device completes the call
transfer by releasing the line; otherwise, 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 towards
the FXO line to restore connection to the original call.
