Registry Entries (Telephony API)
The pluggable terminals are classified into Terminal Superclasses. Each Terminal Superclass has an entry in the registry under the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Telephony\TerminalManager
Below the Terminal Superclass key are entries for each pluggable terminal within the Terminal Superclass.
The entry for each Terminal Superclass is identified by a Terminal Superclass CLSID. This is a unique identifier for a terminal class. The terminal class has an optional attribute: name, which is a friendly name for the terminal class. Each pluggable terminal is identified by a CLSID Terminal class; that is, a GUID.
