The L400, a cost effective desktop phone without a display, is perfect for the combination with the SwyxIt! telephone software.

SwyxPhone IP phones are connected to the local network over the Ethernet. The model L440 has an additional integrated LAN switch, which connects the PC workplace to the local network, requiring only a single LAN port. Therefore, the PC and telephone can share a single LAN port and costs of the network infrastructure are minimised.

The SwyxPhone product line includes the models L400, L420e, L420s and L440. In addition to the standard phone L420 the advanced version L440 has a larger display and more function keys. SwyxWare also supports the connection of Siemens IP phones.
