In modes 2 – 6, audio parameters can be adjusted with AT commands.
Reference Note
Siemens The write command can be used during a voice call to switch back and forth bet-
ween different modes. This allows the user, for example, to switch handsfree
operation on and off. Likewise, the microphone can be muted or switched on during
the call.
Users should be aware that <outStep> is a global setting, i.e. when selecting
another audio mode the value of <outStep> does not change. This is also true for
mute operation which can be set with AT^SNFM or AT+CMUT: If the microphone
is muted and the user changes to another audio mode then the microphone
remains muted until explicitly changed.
