Microsoft .NET Framework
Microsoft .NET Framework 4.7.2 is a prerequisite for SwyxServer and all other Swyx components. It can also be downloaded subsequently via the Windows update feature, or from the Swyx DVD.
SQL Database for the user data
SwyxServer needs a Microsoft SQL database for storing the user and configuration data. You can choose from a variety of options:
Microsoft SQL Server Express 2019, 2022, 2025Microsoft SQL Express can be downloaded directly from the Swyx DVD.
Microsoft SQL Server Standard Edition 2019, 2022, 2025For larger installations, e. g. a installation, please use at least Microsoft SQL Server Standard Edition.
The database server must be set up before the installation of Swyx.
The existing SQL server is not updated in a Swyx update.
Mail server
To send welcome and password reset e-mails and voice messages, you need a mail server that can be reached from SwyxServer. With the Swyx, Call Routing Manager further offers calendar-based call management.
Virus Scanner
If you operate a virus scanner on the computer on which SwyxServer is installed, you should exclude the database files from the scan process.
