C-Soft and AD-HB4 Nena question.

Answer

NENA port audio will only work if C-Soft is first running. NENA audio will continue to route between Phone system and headset if C-Soft or PC is accidentally closed or shut down for whatever reason. Without C-Soft first being launched NENA will not work.

Additional testing shows that if C-Soft was started but couldn't get a license (server operation failure), the user can select Demo Mode and have NENA audio route to headset.
