By setting up a SwyxLink it is possible to implement a connection between two or more SwyxServers. The configuration of this link allows status information (logged off, free, speaking) to be exchanged between users who are not logged on to the same SwyxServer. From version 2011 R2 onwards, the collaboration, video and instant messaging function (only SwyxIt! Messenger, not Swyx Messenger) is also possible across servers. Similarly, the users of one site will be displayed in the Global Phonebook of the other site, and vice versa.

A distinction is made between the following types of connection:

Below is a graphical representation of various scenarios for connecting multiple SwyxServers using different connection types.
