Call Transfer; Call Transfer Configuration - Yealink W60P Administrator's Manual

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.
Yealink IP phones support call transfer using the REFER method specified in
Blind Transfer -- Transfer a call directly to another party without consulting. Blind transfer is implemented by a
l
simple REFER method without Replaces in the Refer-To header.
Semi-attended Transfer -- Transfer a call after hearing the ringback tone. The semi-attended transfer is imple-
l
mented by a REFER method with Replaces in the Refer-To header.
The semi-attended transfer is applicable to that when users do not want to consult with the third party after hearing
the ringback tone, and the third party has not answered the call, the users can cancel transfer or implement transfer.
Attended Transfer (Consultative Transfer) -- Transfer a call with prior consulting. Attended transfer is imple-
l
mented by a REFER method with Replaces in the Refer-To header.
