What is the XiVO UC Assistant ?

The XiVO UC Assistant is a Web application that enables a user to:

  • search contacts and show their presence, phone status
  • make calls through physical phone or using WebRTC
  • transfer incoming or outgoing calls
  • access voicemail
  • enable call forwarding and Do Not Disturb (aka DND)
  • show history of calls


To login, you must have a user configured on the XiVO PBX with:

  • XiVO Client enabled,
  • Login, password and profile configured
  • A configured line with a number


If a user tries to login without a line, an error message is displayed and user is redirected to the login page (this applies also to Desktop Applications )



A Remember me option is available at prompt page to keep you signed in, when you want automatic login.

When logged in as a user with a WebRTC line you can initiate and receive an audio/video call. The video call is possible only from your favorite contacts or the directory search result through the video camera icon. When the called user doesn’t support video calls, call is established as audio only.

In the current implementation you can put the call on hold, go fullscreen, but for the moment you can have only one video call at a time and you can’t transfer the video call. Conference is not supported yet.
