Adds USB Audio Support together with various quality fixes

Improvement(s)

? USB Audio Support on CCX - Phones USB audio mode enables you to use CCX phones configured with the Open SIP base profile as a USB audio device on your computer. Use this mode to take calls from a softphone client, play computer audio through the phone's speakers or use the phone's microphone to record audio.

? Note: CCX 400 business media phones don't support USB audio mode

If the CCX phone comes equipped with the handset, lifting it switches the audio and output from the speakerphone to the handset. Connect a compatible USB or Bluetooth set to the phone to switch the audio to the set instead.
