Syntax
Command Description
This 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.
