Call transfer enables IP phones to transfer an existing call to another party. 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 -- 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.
