UC Federation


There is more to presence than merely identifying whether an associate is “available,” “away,” or “busy.”

For example, there are custom status messages, e.g., “on-road with limited access.” There are also enhanced presence states, wherein the UC platform collects detailed information about a user—such as whether that person is on the phone or in a meeting meeting—and displays it as a presence status so that others can make informed choices about the best way to contact him or her.

UC Exchange supports all presence forms, and it also conforms to each individual UC platform and to the various user-level settings for interruption management and presence access levels.


UC federation allows you to seamlessly chat with external colleagues regardless of their underlying UC platforms.

Multi-User Chat

For UC platforms that support multi-user chat for federated domains, UC Exchange allows users to host group chat sessions and invite multiple federated participants to attend. Federated users can see all participants, including their presence statuses. Essentially, they can view and communicate with those who join or leave the session as if they were on the same platform.

Place a Voice and Video Call

UC Exchange Voice and Video calling makes it rather easy to place voice and video calls. All you have to do is open your UC client and select a federated contact or an nCore user from your contacts list. Your federated business partners don’t have to subscribe to the service or download a plugin to connect.

Receive Voice and Video Calls

To accept calls from federated contacts or nCore contacts, simply select the phone or video button on your client.

Policies and Disclaimers

The UC Exchange UC Federation Service allows customers to set their own permissions. You can control the type of traffic—whether that’s IM, voice, video or file transfers—that is allowed and denied across your business networks and collaborative communities.

Federated User Tagging

The UC Exchange UC Federation Service allows your users to tag other federated users. Tagging allows users to receive notifications when their external peers are online.

Friendly Names and vCard

For UC platforms that support federated vCard functionality, UC Exchange allows your users to see the vCard contact information of their nCore and federated colleagues.


“Is-typing” is an important chat feature that lets users see when the person they are communicating with is in process of sending a new chat message.

The UC Exchange UC Federation Service allows users see if their federated colleagues are still typing a message even if they are on different platforms.
