Recording Feature

Automatically Record your Calls in 3 different Quality levels. Select, if you want to automatically or manually start your Calls.

You can Start/Stop Recordings from your Device-Window in UC-Manager. You also find a shortcut to the Recording-Folder.


Action-URLs for many Call and Software-Events:

  • Call-Start
  • Call-End
  • Incoming Call
  • Incoming Call ended

Connect Hotkeys to Headset-Events

Associate a button press on the headset with a hotkey. This function can help to enable CallControl on unsupported softphone clients. Together with the external applications of the UC-Manager (HookOff.exe, HookOn.exe ...) and the Tapi interface, fully functional call controlling can be enabled on some unsupported softphone clients. (Hotkeys must always be used together with other interfaces. With hotkeys alone it is not possible to accept calls via headset)


Sync your presence between all supported softphones and Quandy-Busylights. Change your actual Presence-State in the Title-Bar of UC-Manager. Here you can also change the Ringtone and Volume of a optional Quando Busylight. 

MSI Installer

The freeVoice UC Manager is also available as an MSI installation package. Click on the Button bellow to get the actual Version of freeVoice UC-Manager as an MSI package.

APIs for freeVoice UC-Manager

We offer also open APIs for our UC-Manager. The APIs are used to remotely control the headset from your own software. (A running instance of the freeVoice UC Manager is necessary).

Follow this link for more Information about the Pipe-API.

With installed UC-Manager, Activate HTTP-API and open in your browser.

In the Installation-Folder, you will find the Exe-Files for the Exe-API (HookOn.exe, HookOff.exe, RingOn.exe...). Take a look at the Estos-configuration as an example.
