TAPIEx ActiveX Control v3.6

ITAPIPhone

The ITAPIPhone interface encapsulates a phone device, setting hookswitch devices, set the volume or gain value.

Just as the line device interface ITAPILine is an abstraction of a physical line device, the phone interface TTAPILine represents a device-independent abstraction of a telephone set. TAPI treats line and phone devices as devices that are independent of each other. In other words, you can use a phone (device) without using an associated line, and you can use a line (device) without using a phone.

Remarks

Hookswitch Devices
A phone device can have multiple hookswitch devices. A hookswitch is the switch that connects or disconnects a device from the phone line. On a telephone, for example, this is the switch that is automatically activated when a user lifts the receiver from the cradle to get a new dial tone.

TAPI defines three types of hookswitch devices for a phone: handset, speakerphone, and headset. Each hookswitch device has a speaker and a microphone component, and operates in one of four hookswitch modes:
OnHook The hookswitch device is onhook, and both its microphone and speaker are disabled.
Microphone only The hookswitch device is offhook, its microphone is enabled, and its speaker is mute.
Speaker only
 The hookswitch device is offhook, its microphone is mute, and its speaker is enabled.
Microphone and speaker The hookswitch device is offhook, and both microphone and speaker are enabled.
