18.5 AT+CMUT Mute control
The AT+CMUT command mutes the microphone input. The command can be used in all audio modes (1 to 6) and
during a voice call only. See AT^SNFS for more details on the various audio modes. As alternative, you can use
the AT^SNFM command.
During an active call, users should be aware that when they switch back and forth between different audio modes
(for example handsfree on/off) the value of <mute> does not change, i.e. the microphone mode is retained until
explicitly changed.
