These constants are used in the PHONECAPS data structure to indicate the hookswitch device capabilities of a phone device. The PHONESTATUS structure reports the state of the phone's hookswitch devices. The function phoneSetHookSwitch and phoneGetHookSwitch use it as a parameter to select the phone's I/O device.
