Modifying The Pcm_Fecc System Flag - Polycom realpresence 1800 Administrator's Manual

● Although PCM is successfully initiated on Microsoft Office Communications client or Lync client, since
FECC feature is not available on these clients none of the PCM options are accessible as the only
available keys are #,*,1..9 and not the navigation keys ("LEFT", "RIGHT", etc.).
