Audio/Video wizard in ProCall

ProCall provides you with an audio/video wizard for selecting or testing suitable devices for audio/video communication and softphone. The wizard shows you the available devices. You can configure or test devices such as the headset, microphone or camera for playing and recording.

How to start the wizard?

You can find the Audio/Video wizard in the ProCall main window. Right-clicking on the Video symbol  or on the three dots top right  shows the menu item Start Audio/Video Wizard.

To the extent that estos ProCall is also available as an icon in the notification area, the Audio/Video wizard can also be started via the context menu for this icon.

Select the audio devices you want to use or test for ProCall for the microphone and playback for AudioChat/VideoChat or softphone.

The Microphone selection field offers you the microphones available on the computer system. The Playback selection field offers you the selection for the desired audio output device. Another audio output device available on the system can be selected for the output of the ringing tone.

Call control

If the selected device offers call control via keys (e.g. call acceptance, mute, etc.), the otherwise gray option "Activate call control via device" is offered. This allows, for example, incoming audio/video chats to be answered and hung up again by pressing the corresponding key directly on the headset. Depending on the terminal manufacturer, this HID (Human Interface Device) functionality or feature is also referred to as EHS/Electronic Hook Switch/electronic call acceptance.

For more information, see the context-sensitive help of the Audio/Video wizard (accessible via the Help button or the F1 key) and ProCall Enterprise online Help.

For some headset manufacturers, the installation of a separate SDK may be required. If, as shown in the following example, the availability of the Plantronics Hub interface cannot be identified by the estos ProCall Enterprise client, this call control option via headset will not be available and a message Please install Plantronics Hub first will appear:

Operation in Terminal Services environments

If estos ProCall Enterprise client is run in a terminal server session or a virtualized desktop, HID functions are generally not available. Since ProCall Enterprise client and headset are running or connected on different hosts, communication via SDK between these components is not possible. The option Activate call control via the device is therefore always grayed out and deactivated in Terminal Server mode.

Due to the lack of HID pairing, even a headset base station will not be able to play a ringtone on an incoming call to the softphone.

Note

The availability of the function depends on system environment, configuration, ProCall version and granted permissions.
