Parameter Description
Web: Transfer Prefix
EMS: Logical Prefix For Transferred
Call
[xferPrefix]
Defines the string that is added as a prefix to the
transferred/forwarded called number when the REFER/3xx
message is received.
Notes:

The number manipulation rules apply to the user part of the
Refer-To and/or Contact URI before it is sent in the INVITE
message.
 This parameter can be used to apply different manipulation
rules to differentiate transferred/forwarded number from the
originally dialed number.
Web: Transfer Prefix IP 2 Tel
[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 blind transfer modes, i.e.,
LineTransferMode = 1, 2 or 3,.
The valid range is a string of up to 9 characters. The default is
an empty string.
Web/EMS: Enable Semi-Attended
Transfer
[EnableSemiAttendedTransfer]
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
[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-To header.
The call is then 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
[KeyBlindTransferAddPrefix]
Determines whether the device adds the Blind Transfer code
(defined by the KeyBlindTransfer parameter) to the dialed
destination number.
 [0] Disable (default)
 [1] Enable
