Several components are required for setting up SwyxWare, with SwyxServer representing the actual central system component.

Although SwyxServer performs an important central function, this does not mean a "central bottleneck". In contrast to conventional telephone systems and IP telephone systems with a central switching unit, SwyxServer is only minimally involved in setting up and controlling the call: SwyxServer essentially takes on elementary functions relating to a connection setup - such as determining the associated IP address for a number to be called - and establishes its availability, while the actual call with SwyxWare then takes place directly between the participating terminal devices. It is therefore easily reconstructed, so that SwyxServer satisfies even medium-sized firms and can initiate and control hundreds of calls in parallel without causing internal "busy" situations.

Due to the fact that not only connection control data but also voice, fax, or video data are transported as IP packets, SwyxWare retains complete control at all times over all existing connections. This allows SwyxWare to easily create, play, or record voice information, for example, during connection control and depending on the current data structures. In this way it can function as an automatic announcement system, as an answering machine, as voice messages, or play any music on hold with no additional hardware required.

On the subscriber side, SwyxServer recognizes "Users", who can use a telephone client with suitable handsets and headsets, or various IP desk telephones.

For SwyxWare a backup server is also available with the option pack, SwyxStandby which automatically takes over the tasks of the primary master SwyxServer if this fails.

Also of great importance for a SwyxWare installation is the link to the existing mail system. SwyxServer saves all voice messages and all fax messages as email attachments on the firm's email server, often but not necessarily a Microsoft Exchange server.
