17.5 <strong>AT</strong>+CMUT Mute control<br />

The <strong>AT</strong>+CMUT command mutes the microphone input. The command can be used in all audio modes (1 to 6) and<br />

during a voice call only. See <strong>AT</strong>^SNFS for more details on the various audio modes. As alternative, you can use<br />

the <strong>AT</strong>^SNFM command.<br />

During an active call, users should be aware that when they switch back and forth between different audio modes<br />

(for example handsfree on/off) the value of does not change, i.e. the microphone mode is retained until<br />
