Even if you want to start with a small system at first – our COMmander 6000RX with its fully modular design makes a perfect investment in the future. It is suitable for 19” racks, offers 38 exchange channels and up to 112 internal ports. To connect with the public telephone network, you may choose between VoIP trunk channels, ISDN basic lines and a primary rate interface, while internal participants share the VoIP, ISDN and analogue connections.


Its full potential, however, lies idle until your demands increase and your communication requirements grow. Are you hoping to enjoy uninterrupted communication via wireless DECT system phones, or do you have a centralized voicemail and fax system with Unified Messaging in mind? No problem – simply plug the relevant extension into one of the COMmander 6000RX’s 15 open slots. You can even tap the advantages of the “Cloud” for your company.


This high-performance server can easily be integrated into your local network which ensures that all your subsidiaries and home offices are optimally connected to the system. Integrated web applications also enable you to configure and maintain your system from wherever you happen to be! The COMmander 6000RX is designed to be integrated in structured cable networks. Connections are easily accessible via patch panels with RJ-45 jacks, and retrofitting the system with extension modules is done directly on the front panel. As you see, this system can be designed to meet your requirements perfectly – from the smallest expansion stage up to the full version.

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

Auerswald supports discretion and efficiency in private clinics
Sector Employees
Healthcare 23
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."

Telecommunication solutions for authorities and administration – Municipal administration

Making the tasks of authorities and administration easier
Sector Employees
Authorities and administration 132
Martin S., Deputy Head with 132 employees

"As is well known, authorities bear a particular responsibility when it comes to equipment procurement. Therefore, we placed great emphasis on sustainability and long-term cost reduction through VoIP and process optimisation during our call for tender for a communication system, i.e. we wanted to save as much time as possible for employees. The tender from FONtevo scored the best, especially as the hardware was exceptionally energy-efficient – the stipulations from our 'Green IT' program were thus fulfilled. A COMmander 6000RX and 42 new telephones (COMfortel 1200 / COMfortel 1600) were purchased – the rest of our equipment was easy to transfer over, as were the office peripherals. The work processes have benefited enormously from the installation, partly because we were able to integrate new software, bringing us one step closer to the 'paperless office'. And if we switch our IT structure to IPv6 in the next year, the COMmander can be adapted with just a free software update and absolutely no additional charges."

Telecommunication solutions for wholesale and retail – Branch operation

Successfully networking branches
Sector Employees
Wholesale and retail 62
Julia B., Executive Assistant with 62 employees

"When I was asked to obtain quotes for a modern telephone system, I had certain search criteria in mind, from Voice over IP to unified communications, but otherwise I had very little knowledge. A specialised dealer then took the time to go through the quotes with me point by point. It then became very clear that the cheapest option was also the best. Since then, we have had a telephone server (COMmander 6000RX) that connects practically our entire company. Every branch can make telephone calls economically over the internet – but everything is controlled by the server in reception. It also features an interface for connecting our ERP and CRM systems that are linked using the 'ESTOS ProCall' software. This means that we don't just have presence management that incorporates all branches, if a customer calls it is also possible to view the status of an order from every workstation. In any case, my boss is extremely pleased. He always takes his handset COMfortel M-210 with him when visiting a branch, meaning he is automatically linked with head office on site. As an aside, I am also very satisfied, because I now have a particularly fancy phone: it is called COMfortel 3600 IP and can be equipped with all possible apps."
