How to Use Tel Protocol with Virtual Office Desktop


Using the tel protocol to initiate outbound calls through Virtual Office Desktop (VOD).

Applies To

Virtual Office Desktop v 6.0


  1. In the address bar of a web browser window, enter tel:// followed by the phone number you wish to dial.
    • Example: tel://15558675309
  2. If the tel protocol is not already assigned to another application, you will be prompted to select an application to place the call. To dial with VOD, select the application and click Open Link.
    • To make VOD your default application for the tel protocol, check the box Remember my choice for tel links before clicking Open link.

  3. To set up Virtual Office Desktop as the default app for tel protocol dialing:
    • Windows:
      1. Settings > Apps > Default Apps.
      2. Select Choose default app by protocol.
      3. Under Tel URL:tel, select 8x8 - Virtual Office.
    • Mac (VOD 6.1+ required):
      1. FaceTime > Preferences > Settings tab.
      2. Choose 8x8 - Virtual Office on the Default for calls dropdown.

Additional Information

By default, Virtual Office Desktop version 6 will assign itself to handle the tel protocol every time it is launched. Skype for Business also does this.

If you use both applications, and you need Virtual Office Desktop to respond to clicked phone numbers that are associated with the tel protocol, launch Skype first and then Virtual Office Desktop.
