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)

  • 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

Instant Messaging

It is possible from the assistant to send chat messages and have private text conversation. It is possible to deactivate it if this feature is not suitable for your needs or if you have already an external chat application, see Disabling chat in UC Assistant and Switchboard.

There are two possible behaviors for handling messages:

  1. No persistance (default) : Each message is an instant message that can be sent to another user logged in. messages are not stored anywhere and will be discarded once you refresh the page or log out.

  2. With persistence : Can be enabled with Chat Backend. This allows then

  • To send messages to offline users

  • To retrieve you conversation history with other parties

  • To receive notifications when you logs in if you have unread messages that has been received while you were disconnected.


When you send a message, you are notified if the message was sent successfully or if the message was not received because the recipient is not logged in.

When you receive a message, you are notified with a orange badge on the message tabs. If you are using the desktop application, the electron tray icon also shows an orange badge. You will also have a notification from your web browser or a system notification if you are using the desktop application.
