Table A-46: Call Transfer Parameters
Enables the Call Transfer feature.

[0] Disable = Disable the call transfer service.

[1] Enable = The device responds to a REFER message
with the Referred-To header to initiate a call transfer
(default).
Notes:

To use call transfer, the devices at both ends must
support this option.

To use call transfer, set the parameter EnableHold to 1.
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 number from
the originally dialed number.
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 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.
Determines the device behavior when Transfer is initiated
while in Alerting state.

[0] Disable = Send REFER with the Replaces header
(default).

[1] Enable = Send CANCEL, and after a 487 response is
received, send REFER without the Replaces header.
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.
