PHONEHOOKSWITCHDEV_ Constants

The PHONEHOOKSWITCHDEV_ bit-flag constants describe various audio I/O devices each with its own hookswitch controllable from the computer.

PHONEHOOKSWITCHDEV_HANDSET

This is a standard ear- and mouthpiece phone.

PHONEHOOKSWITCHDEV_HEADSET

This is a headset connected to the phone set.

PHONEHOOKSWITCHDEV_SPEAKER

This is a built-in loudspeaker and microphone. This could also be an externally connected adjunct speaker to the telephone set.

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.
