Call Transfer
Call transfer enables IP phones to transfer an existing call to a third party. For example, if party
A is in an active call with party B, party A can transfer this call to party C (the third party). Then,
party B will begin a new call with party C and party A will disconnect.
IP phones support call transfer using the REFER method specified in RFC 3515 and offer three
types of transfer:

Blind Transfer
-- Transfer a call directly to another party without consulting. Blind transfer
is implemented by a simple REFER method without Replaces in the Refer-To header.

Semi-attended Transfer
-- Transfer a call after hearing the ringback tone. Semi-attended
transfer is implemented by a REFER method with Replaces in the Refer-To header.

Attended Transfer (Consultative Transfer)
-- Transfer a call with prior consulting.
Attended transfer is implemented by a REFER method with Replaces in the Refer-To
header.
Normally, call transfer is completed by pressing the transfer key. Blind transfer on hook and
attended transfer on hook features allow the IP phone to complete the transfer through on-
hook.
When a user performs a semi-attended transfer, semi-attended transfer feature determines
whether to display the prompt "
n New Missed Call(s)
" ("n" indicates the number of the missed
calls) on the destination party’s phone LCD screen.
