COMfortel® WS-500S

The single-cell IP DECT system that can handle so much more when needed

Up to 20 handsets

Up to 8 parallel calls

Professional zero-touch configuration via auto-provisioning

Upgradeable from single-cell system to a multi-cell system

Expansion with up to two WS-500S possible (mini multicell operation)

Your advantages in detail

One for all: The WS-500S is inherently the affordable single-cell system for entering the IP DECT world. Already in this version up to 8 simultaneous calls are supported and up to 20 handsets can be registered. This makes it the ideal basis for offices, medical practice and smaller companies.

The best thing about it: with the upgrade licence WS-500S Multi, this base can be extended to the same feature range as the multi-cell WS-500M system with up to 250 handsets and up to 60 parallel calls.

DECT technology is digital and encrypted. It therefore offers comprehensive security. Wireless eavesdropping of a call is not possible. The network security of the WS-500S is additionally enhanced by SIP security. End-to-end security is therefore guaranteed.
