The COMfortel WS-650 IP is an IP DECT server for all company sizes. The IP DECT multi-cell system ensures the permanent availability of employees throughout the company. Calls can be made even while moving around company premises. The connection is automatically – and of course seamlessly – transferred to the next base. Its professional features, such as access to address books provided centrally via LDAP or in the cloud, or its extreme scalability with up to 1,024 base stations and 4,096 mobile users, makes this system a good investment for the future.


The COMfortel WS-650 IP DECT server is a prime example of adaptability: the basic configuration enables cordless telephony for 30 DECT handsets but given that it offers 32 call channels to the PBX system, this would not be much of a challenge. Especially since it can be expanded to 1,024 VoIP channels with additional hardware. A simple software upgrade lets you connect up to 4,096 DECT handsets, controlled by up to 1,024 radio cells. Perfectly coordinated, these components ensure superior communication and maximum freedom of movement.


It is clearly a business solution that offers a high level of security: to optimally prevent any data abuse, you may opt for SRTP (Secure Real-Time Transport Protocol) which ensures fully encrypted VoIP connections.


Configuring the IP DECT multi-cell system as well as automatic provisioning of the entire DECT infrastructure, including handsets, can be done via a convenient web interface. Mounting brackets for fixed installation in a 19 inch cabinet are part of the package.


The entire IP DECT wireless system comprises several components: the COMfortel WS-650 IP server, up to 1,024 COMfortel WS-Base DECT bases, if necessary, a COMfortel WS-R2/R4 repeater to extend the range of the bases, and our COMfortel M-100, M-210 or M-310 DECT handsets.

Telecommunication solutions for healthcare – Nursing and residential homes

FONtevo offers greater vitality for nursing and residential homes
Sector Employees
Healthcare 17
Caren P., Managing Director with 17 employees

"Some of our residents are still very sprightly but others are dependent on support for every movement. Our nurse call system, which is connected to an alarm server, is therefore extremely important. Although we are well equipped to provide first aid, it is often necessary to make emergency calls. So it's comforting to know that such emergency calls always take priority for the PBX – we have invested in an extremely efficient COMmander 6000RX. Since we recently linked it with the 'tekowin Heim' software however, controlling the telephones is just one of the many things it does. The system helps us with invoicing, provides statistics, archives correspondence – it is quite remarkable how much it can do! It is also handy that we can control all video cameras in and around the building using the telephone, a COMfortel 3600 IP, in the reception area – a real security advantage, because now and again a resident may get 'lost' and suddenly lose their bearings. What's more, our previous DECT solution was outdated and we have replaced it with an IP-DECT solution, also from the same brand. In addition to being more robust, the new cordless telephones COMfortel M-310 are also easy to clean. Especially for us, where everything is subject to special hygiene requirements, this was an extremely important point!"

Telecommunication solutions for healthcare – Private clinic

Dr Henry V., Senior Physician and Hospital Director with 23 employees

"A clinic cannot depend on a good medical reputation alone. Today, efficiency is just as important for the successful running of a clinic as providing optimal care to patients. When choosing our PBX, there were therefore two decisive criteria: it must support both medical operations and administrative processes. We chose a COMmander 6000RX – it controls the nurse call system via the connected alarm server, acts as a switchboard, keeps an eye on the entrance and even helps with invoicing because it is linked to the 'tekowin Heim' software. In practice, it is as though the PBX manages bookings, writes invoices, creates statistics... and incidentally happens to ensure that internal and external telephony also function reliably. Every employee has a cordless telephone (COMfortel M-310) that provides direct access to the switchboard functions such as operating the door opener, for example. Extremely important to us: cleaning using disinfectant can't damage this robust telephone. There is also a COMfortel 3600 IP in every department as this telephone can display images from all of the surveillance cameras on the premises. On the other hand, a modest COMfortel 600 is more than sufficient for consulting rooms, providing a convenient way to make phone calls. All devices from one manufacturer – I am positive that this was a very wise decision."

Martin E., Managing Partner with 25 employees

"We have fairly large premises here with several assembly facilities where our engineers always disappear into a 'dead zone'. In complete ignorance once, we asked one of the 'big names' in the telephone industry just how much such a professional IP DECT solution would cost – we almost fell of our chairs when we heard the amount. It was when looking for alternatives that we then came across a specialised dealer situated just nearby. He carried out a DECT measurement on-site at our premises without further ado, strategically positioned six radio cells (COMfortel IP DECT system with Server WS-650 IP and six WS-Base). Since then, everything has worked perfectly, and we are very happy with our new cordless handsets M-100 which are really insensitive to rough treatment. The best bit: we were able to continue using our existing PBX, a COMmander 6000R, which supplied our 24 analogue desktop phones and both COMfortel 2600 IP phones, even though the entire premises is only called via VoIP. So, we got exactly what we wanted for a fraction of the cost. We then invested the money we saved in video surveillance: there are now four IP cameras mounted in the entrance areas – I can conjure up the images at the touch of a button on the display of my new COMfortel 3600 IP whenever I want to."

George Z., Managing Partner with 22 employees

"On good days we accept up to eighty incoming calls at our headquarters alone – I cannot and have no desire to accept them all myself. To ensure that no one has to wait for long, the PBX COMmander 6000R sounds whenever anyone is interested in a test drive, is put through to the workshop or wants to offer their vehicle for sale. The whole process is quick and customers are happy that they don't need to explain what they actually want three times over. The best bit: our database is linked directly to the PBX. If, for example, one of my regular customers calls, their name and other important details appear on the display before I've even picked up the receiver. It also works the other way around too: if I want to call a customer, all I have to do is search for them in the central address book and click on the number. And if I don't want to be interrupted during a call, a simple press of a button is all it takes to pass all calls to my secretary. We have fairly large business premises here and three additional locations, but since we installed a COMfortel WS-650 IP multi-cell DECT system, everyone really is contactable at the drop of a hat – even if they are at another site. The DECT handsets – we all have the COMfortel M-100 in various colours – at the other locations are also connected to our switchboard. Nothing has ever made us so easy to contact before."
