Values in the range 0x80000000 to 0xFFFFFFFF can be assigned for device-specific extensions; values in the range 0x00000000 to 0x7FFFFFFF are reserved.

The PHONEBUTTONFUNCTION_ constants have values commonly found on current telephone sets. These button functions can be used to invoke the corresponding function from the switch using lineDevSpecificFeature. Note that TAPI does not define the semantics of the button functions; it only provides access to the corresponding function. The behavior associated with each of the function values above is generic and may vary based on the telephony environment.
