Your advantages in detail

The fully modular COMpact 5200 combines all the functions of a large ICT system in a small space: it can be tailored to individual needs, just like our "big" communication servers, and it can integrate existing analogue and ISDN devices and manage the new cordless DECT systems smoothly for mobile coverage over huge areas.

The COMpact 5200 easily and securely meets the requirements of the home office and modern temporary workstations with optional soft clients for computers, tablets and smartphones. The cost-effective COMfortel SoftPhone for voice and chat is available at the entry level. Those who need more extensive functions and more intensive integration into business processes will find the optimal UCC solution with PBX Call Assist.

Above all, you can use it to take full advantage of Internet telephony – from easier administration to long-term cost savings! Last but not least!
