SwyxServer manages, controls, and monitors all functions and services of Swyx business telephony. Its configuration level in relation to the maximum number of subscribers and the optimal functions determines the capability of the overall system.

Swyx administration is performed using an add-on module ("snap-in") for the "Microsoft Management Console (MMC)" and enables the convenient setup and management of SwyxServer and all other Swyx components.

The concept of Number Mapping and the property "Location", both of users and of trunk groups, enable extensive flexible arrangement of the internal number scheme.

See 10 Numbers and Number Mappings.

With the call permissions, you can define the options for users to make calls. Forwarding of calls via trunk groups can likewise be restricted with the help of the call permissions

Function profiles define the use of additional Swyx features. Administration profiles define different levels of administration options.

See 9 Profiles.

"Trunk" denotes a connection to another network, e.g. the public telephone network. A connection to another network can be e.g. an "ISDN trunk", a connection to the Internet an "SIP trunk". Connections or trunks of the same type are combined to form groups. The trunks of a trunk group then have the same properties (such as the same connection protocol or the same rights parameters). The trunks of a trunk group are thus primarily "capacity expansions" from the user's point of view, with no further differences for their use. A trunk must always be a member of a trunk group.

Different trunk groups can be differently prioritized. The result is e.g. that calls are handled with preference given to a server-server connection. If this is not available, a lower-priority path is chosen, e.g. an ISDN trunk.

SwyxIt! Classic is the high-performance telephone for your Windows PC. Due to its freely configurable user interface, SwyxIt! Classic can easily be customized to meet your personal needs. The call takes place with a handset (usually with a USB cable attached to the PC) or a headset.

With SwyxIt! Classic in CTI mode (CTI SwyxIt!), you can control phones from your computer. There are various functions available to users with SwyxCTI and SwyxCTI+. See also help.enreach.com/cpe/latest.version/Client/Swyx/en-US/#context/help/phone_control_CTI_$.

In addition, Swyx offers the Call Routing Manager, a schedule-based call management tool that routes incoming calls to a specific user or group of users in a variety of ways based on different criteria.

Furthermore, the Swyx installation consists of a number of services that are installed as separate processes along with the SwyxServer, or on a remote server system if this is desirable or recommended for capacity reasons. Such services are e.g.
