In order to achieve optimal audio quality with the different headset types it is
recommended that the GUI and parameter called “Name of user headset profile” is
altered to match the headset type being used. This is done in the PDM see Configuration
Manual, Cordless telephone DT690, TD 92503GB. The default setting for this parameter is
microphone on a boom i.e. the audio is optimized for using a headset with microphone on
a boom.
