Parameter Description
Web: Transfer Prefix IP 2
Tel
CLI: xfer-prefix-ip2tel
[XferPrefixIP2Tel]
Defines the prefix that is added to the destination number received in the
SIP Refer-To header (for IP-to-Tel calls). This parameter is applicable to
FXO/CAS blind transfer modes, i.e., LineTransferMode = 1, 2 or 3, and
TrunkTransferMode = 1 or 3 (for CAS).
The valid range is a string of up to 9 characters. The default is an empty
string.
Note: This parameter is also applicable to ISDN Blind Transfer,
according to AT&T Toll Free Transfer Connect Service (TR 50075)
“Courtesy Transfer-Human-No Data”. To support this transfer mode, you
need to configure the parameter XferPrefixIP2Tel to "*8" and the
parameter TrunkTransferMode to 5.
Web/EMS: Enable Semi-
Attended Transfer
CLI: semi-att-transfer
[EnableSemiAttendedT
ransfer]
Determines the device behavior when Transfer is initiated while in
Alerting state.
[0] Disable = (Default) Send REFER with the Replaces header.
[1] Enable = Send CANCEL, and after a 487 response is received,
send REFER without the Replaces header.
Web: Blind
EMS: Blind Transfer
CLI: blind-transfer
[KeyBlindTransfer]
Defines the keypad sequence to activate blind transfer for established
Tel-to-IP calls. The Tel user can perform blind transfer by dialing the
KeyBlindTransfer digits, followed by a transferee destination number.
After the KeyBlindTransfer DTMF digits sequence is dialed, the current
call is put on hold (using a Re-INVITE message), a dial tone is played to
the channel, and then the phone number collection starts.
After the destination phone number is collected, it is sent to the
transferee in a SIP REFER request in a Refer-
terminated and a confirmation tone is played to the channel. If the phone
number collection fails due to a mismatch, a reorder tone is played to the
channel.
Note: For FXS/FXO interfaces, it is possible to configure whether the
KeyBlindTransfer code is added as a prefix to the dialed destination
number, by using the parameter KeyBlindTransferAddPrefix.
EMS: Blind Transfer Add
Prefix
CLI: blind-xfer-add-prefix
[KeyBlindTransferAdd
Prefix]
Determines whether the device adds the Blind Transfer code (defined by
the KeyBlindTransfer parameter) to the dialed destination number.
[0] Disable (default)
[1] Enable
Note: This parameter is applicable only to FXO and FXS interfaces.
EMS: Blind Transfer
Disconnect Timeout
CLI: blind-xfer-disc-tmo
[BlindTransferDisconn
ectTimeout]
Defines the duration (in milliseconds) for which the device waits for a
disconnection from the Tel side after the Blind Transfer Code
(KeyBlindTransfer) has been identified. When this timer expires, a SIP
REFER message is sent toward the IP side. If this parameter is set to 0,
the REFER message is immediately sent.
The valid value range is 0 to 1,000,000. The default is 0.
Web: QSIG Path
Replacement Mode
CLI: qsig-path-
replacement-md
[QSIGPathReplacement
Mode]
Enables QSIG transfer for IP-to-Tel and Tel-to-IP calls.
[0] IP2QSIGTransfer = (Default) Enables IP-to-QSIG transfer.
[1] QSIG2IPTransfer = Enables QSIG-to-IP transfer.
