Siemens MC55 AT manual 17.5 AT+CMUT Mute control, At+Cmut=?, At+Cmut?

17.5AT+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.
