Mediant 3000
Parameter Description
[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).
Web/EMS: Line Transfer
Mode
[LineTransferMode]
Defines the call transfer method used by the device. This parameter is
applicable to as well as 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:

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 Software License Key.
Message Waiting Indication (MWI) Parameters
Web: MWI Off Digit
Pattern
EMS: MWI Off Code
[MWIOffCode]
Defines the digit code used by the device to notify the PBX that there
are no messages waiting for a specific extension. This code is added
as prefix to the dialed number.
The valid range is a 25-character string.
Web: MWI On Digit
Pattern
EMS: MWI On Code
[MWIOnCode]
Defines the digit code used by the device to notify the PBX of
messages waiting for a specific extension. This code is added as
prefix to the dialed number.
The valid range is a 25-character string.
