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
  • chat between XiVO users also using UC assistant


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

  • CTI Login 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.
