Auto Answer
Yealink phones support answering a SIP call or an IP address call automatically. Auto answer is configurable on a
per-line basis, while IP address call is not.
By default, the phones will not automatically answer the incoming call during a call or while dialing even if the auto
answer is enabled; and the incoming call will not be automatically answered after you end the current call or cancel
the dialing. You can configure how the phone answers the call automatically.
