The number of telephony clients who can log on to SwyxServer is limited to four per user. This means that a user can e.g. log on simultaneously with a desktop client, a SwyxPhone at the workstation and a further SwyxPhone in the conference room. The logon with a mobile client is not taken into account in this calculation.

The purchased user numbers limit the number of different users logging in simultaneously to SwyxServer; it is possible to configure more users than the number licensed.

In SwyxWare for DataCenter, all configured users are recorded in the usage report and thus licensed.
