Table 3-49: Voice Mail Parameters
Parameter Description
General
Voice Mail Interface
[VoiceMailInterface]
Enables the voice mail application on the device and determines
the communication method used between the PBX and the device.
[0] None (default)
[1] DTMF
[2] SMDI
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.
