Supporting telephony hardware

To implement standard functions and features for a specific telephony environment, you need to:

  1. Derive a new line class from TTelephoneLine.
  2. Override the pure virtual line functions.
  3. Derive new feature classes for the features supported by the hardware.
  4. Override the Activate and Deactivate functions for the new feature classes.
  5. Derive feature controls for the supported features.
  6. Write an installer.
    The installer collects configuration information, such as line or site-specific information, and stores it in a configuration file.
To add new features and functions, you derive new feature and control classes directly from TTelephoneLineFeature and TTelephoneLineFeatureControl.

To support specialized terminal equipment, you derive new classes from TTelephoneHandset and TTelephoneHandsetHandle.
