Music on Hold (MoH) Configuration

When a call is placed on hold, the phone will send an INVITE message to the specified MoH server account accord-
ing to the SIP URI. The MoH server account automatically responds to the INVITE message and immediately plays
audio from some source located anywhere (LAN, Internet) to the held party. For more information, refer to draft RFC
draft-worley-service-example.
The following table lists the parameters you can use to configure music on hold.

Call Mute

You can mute the microphone of the active audio device (handset, headset or speakerphone) on Yealink phones
during an active call or when the phone is on the pre-dialing/dialing/calling/ringing screen. The call is automatically
muted when setting up successfully. Muting before a call is answered prevents the other party from hearing the
local discussion.
You can activate the mute feature by pressing the MUTE key. Normally, the mute feature is automatically deac-
tivated when the active call ends. You can use keep mute feature to keep the mute state persisting across the calls.
Note: Muting microphone on the pre-dialing/dialing/calling/ringing screen is not available on T23P/T23G/T21(P) E2
phones when the keep mute feature is disabled.
