Description
Headset
Speaker device
Change these fields only if you want to override the device selected
by zero-touch device configuration.
Microphone device
In both these fields, select the headset you are using.
The headset is the device that is usually used for audio out (the sound
you hear) and audio in (recording your voice). The only situation in
which the headset is not used is when the Speaker Phone button on
the dialpad is pressed.
Therefore, unless you will always be using Softalk in speakerphone
mode, you must make a selection here.
Select the headset in both the Speaker device field and Microphone
device field
Use acoustic echo
cancellation (AEC)
Reduces the echo effect that can arise with a speakerphone or that
can arise if the sound from the speakerphone or headphone leaks
into the microphone. Turning this feature on improves sound quality.
Typically on.
