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 RFC 3515 and offer three types of transfer:
