Note:
Handset Mode is for audio path and GXP2200 dialer control when running 3rd party app that uses media
path. Currently there are three options supported:

Enabled: Default mode. When handset is lifted, audio will come through handset and the GXP2200
default call screen will show.

Disabled: In this mode, when running the 3rd party app, if handset is lifted, the audio path will switch
to handset but GXP2200 default call screen won't show (users won't hear dial tone either). Onhook the
handset, the audio path will be switched to speaker. Under this mode, even the GXP2200 is not using
the 3rd party app, picking up the handset will not activate the GXP2200 dialer. (Users can still use
Speaker button to activate GXP2200 dialer under this mode.)

Auto: In this mode, the GXP2200 will automatically detect if the audio path is used by 3rd party app
first. If so, it will use the handset mode "Disabled". Otherwise, keep it in "Enabled" mode. Please note
that running the 3rd party app doesn't necessarily mean the audio path is used by the 3rd party app. If
the audio path is not occupied by the 3rd party app, the GXP2200 will still use the handset mode
"Enabled".
