You can add custom keys in the SoundPreferences subtree at the same level as the All, DTMF, 
DialTone, OriginatingTone, and RingInTone keys. The SoundPreferences array contains items 
corresponding to these custom keys. Any custom element that you add must follow the same 
hierarchy in the registry as that used by the existing top level elements.

The format of the SoundPreferences Arguments array follows. 

This configuration is stored in the Windows System Registry database and many of the values 
are set when the CTI OS Server Setup is run. Custom configuration can be set at a later time by 
using the Windows Registry Editor. 

The OnHeartbeat event is generated when a heartbeat response is received from a CTI OS server. It
