XPhone Connect Federation interconnects users of the XPhone Connect Server with external contacts who use a SIP federation-enabled system such as Microsoft Teams or also XPhone Connect.

Between users of these systems the presence indication of the respective contact is exchanged, likewise the contacts of the federating systems can use instant messaging for the exchange of messages (1:1 chat, no attachments like pictures).

Administrative defaults regulate whether presence information is transmitted externally with or without the user’s prior consent - but users of the XPhone Connect Server always receive presence requests from their federated contacts in the XPhone Connect Client and can enable or disable the transmission of presence themselves if necessary.

Federation requires an Office Plus license for the user.


For more information regarding the setup, see the Federation chapter.
