  • Unified communications

    Unified communications

    The demand for communication is growing steadily in all areas of business. The purpose of all communication media is to enable enterprises to act faster and with more flexibility in the market. That’s why it’s essential to provide all staff members – including mobile staff – with remote access to all important company information and to fully integrate home office employees into the communication structure. This requirement can be expressed in a need for centralized cross-media collaboration between contacts. And such collaboration can only be successful when the essential information is available at all times, when all employees have high-quality connections and when communication processes are efficient. Whether what you need is a web or video conference, or a face-to-face meeting, WTG uses unified communications solutions from a wide variety of manufacturers in its applications, allowing us to offer our customers the state-of-the-art UC solution that suits their needs.

  • Mobility / One number / BYOD

    Mobility / One number / BYOD

    Maximum flexibility at a single contact number, and above all from a single mobile device. The age of depending on proprietary end devices is long over. Today’s employees bring their own devices along with them into the company so that all their contacts can reach them at a single number. You can trust our mobility solutions.

  • Contact centres

    Contact centres

    Contact centres are the best portals available today for communication with your customers. Bundled multimedia communication in real time, combined with asynchronous media, currently dominates the communication landscape provided by contact centres. We can meet all your technological requirements in the area through our state-of-the art product and service portfolio, covering all the latest communication processes. Our experts know how to convert your business requirements into the right technical design concept. We also provide support throughout the entire process of converting your communication requirements into reality.

  • Video conferencing

    Video conferencing

    Multi-location meetings with customers, suppliers and employees are always time-consuming and expensive. With our video conferencing solutions you can save money at the same time as improving productivity. Your employees can use video-call technology to participate in all important conversations and discussions any time and from anywhere, using a range of different devices, including in-room devices, desktops, smartphones or tablets.

  • Web conferencing

    Web conferencing

    A major challenge for modern business units is to be able to collaborate virtually with customers, suppliers and employees. Such shared activities as working in teams on documents, or brainstorming strategies and products are increasingly a part of the everyday work of modern businesses. Our web conferencing solutions fully equip your virtual teams for collaborative work, and support their efforts to use resources more efficiently and cost-consciously.

  • Cloud solutions

    Cloud solutions

    Centralisation and standardisation as a means of increasing operational efficiency and improving service availability are two areas currently impacting on IT strategies for implementing new information and telecommunication technologies. Perhaps you’re looking to get the benefits of a cloud solution, but can’t use public cloud service as it doesn’t conform with a legally required standard? We can provide the comprehensive portfolio of cloud solutions that help you implement and run the private cloud strategy that best suits your needs.


Secure networks – we really need to be able to trust them! We help you increase your response speeds without neglecting security.

  • Network infrastructure

    Network infrastructure

    Network outages mean disaster to your employees and customers. That’s why it’s vital that your IT service provides high-quality, highly secure access at all times. You can meet this challenge through choosing a convergent enterprise network. Users benefit from consistently high connection quality, while your IT service can control both cable and wireless components via a central management system. Depending on the needs of the applications you are using, the infrastructure adapts in real time from system core to access area as required. We help you to simplify your network, enhance user experience and reduce total cost of ownership (TCO).

  • Content security & spam protection

    Content security & spam protection

    Protect your enterprise network from malware and other threats transmitted by e-mail. We can analyse your current set-up and identify its weak points. We’d also be delighted to run a full security audit for you. Either way, our intervention will help to improve your IT security.

  • Server systems

    Server systems

    We provide custom-designed service solutions tailored to your individual needs. No matter what those needs might be – webservers, file servers or even high-performance virtual solutions. Naturally, we install all products fully key-in-hand. We’d be very happy to present you with a number of different migration options, or even to take over the IT operations for your solutions, running them from a secure data centre.

  • Virtualisation


    It is only through virtualisation that businesses can make the most efficient use of the computing power and storage capacities available to them. What the term “virtualisation” of IT infrastructure means is that the service provider does not provide customers, services and business applications with a particular physical machine. What they provide instead are the virtual resources that deliver precisely the performance your systems need when they need it. Virtualised data centres give your IT management much more flexibility, thus saving you money. We at WTG know how to merge the worlds of IT, telecommunication and security technologies together on virtualisation platforms, and can even take over the operation of such systems in their entirety on behalf of our customers if required.

  • Backup & storage

    Backup & storage

    For very many businesses, data is their most valuable asset. So losing data can do very serious damage. WTG keeps data secure and can restore lost data within a very short time after a system failure. Find out how your individualised data protection design using our solutions can put you on the road to success and ensure you never suffer such losses.


We take our partnerships seriously. In every service WTG provides.


Service transitioning
The supposed intensive effort involved in changing over from one service provider to another often makes businesses unwilling to go down new paths. We have completed a great many such service transitions and can draw on a deep reservoir of experience, giving us the skillset you need to keep cost and effort in service transitions to an absolute minimum.


Service management processes
The task of operating system platforms, particularly for real-time applications, poses serious challenges to businesses. Aside from dealing with technical concerns, it is also our mission to put life into the service management processes, roles and functionalities that allow you to offer the best service possible to your customers. With the experience we have under our belt, we’re happy to take on roles defined within the ITIL service model, putting you on the road to professional service management.


Asset takeover and managed service migration
In some customer scenarios, it can be impossible to immediately migrate existing system environments over to new technologies – even where the need, aspiration or pressure from customers to introduce new functionalities is urgent. For just such cases, WTG offers a number of migration scenarios – from integrating systems into our cloud services within a hybrid model to fully-fledged asset take-over and soft migration onto a new platform using our managed services. Together we can find the best possible value-for-money available on the market to fit your needs.

Professional Services

An essential element in utilising the added value potential of new technologies in your business operations: our professional services.

  • Consulting


    In what direction is technology going at the moment? What areas do particular business sectors need to keep an eye on in the future? What sorts of solutions are becoming essential to the success of businesses? Our consultants can answer all these questions.

    IT organizations are now facing the challenge of implementing the competing demands of their various business segments through the use of complex technical designs. The accumulation of a large number of different systems integrated into your IT infrastructure can make it hard to retain the comprehensive and accurate knowledge you need to develop or evaluate business cases.

    Our consulting services can provide the support you need in requirements definition, technical auditing, architectural design and technology workshops. Or we can show you new product enhancements and the as yet unimagined potential of systems and software already implemented on your infrastructure.

    We ensure that the image you present to your users is one of total professionalism, and help you provide them with the best possible solutions, using the available technology to the full.

  • Project management

    Project management

    The key to success when implementing a complex IT communication system is professional project management. WTG has accumulated decades of experience in the widest possible variety of project situations. To deliver ‘in time, in quality and in budget’ is our prime goal and our solemn promise to our customers. We can either support you or lead you – depending on your needs – all through the implementation or conversion of your IT, telecommunication and security systems.

    Our approach is to adapt ourselves to the needs of each individual customer project using modern project management methods and deploying comprehensive technical expertise, keeping project conversion times short and additional investment needs low. Effective project management reduces the need for further investment down the road in service management at the same time as increasing user satisfaction during and after the implementation of new systems and functionalities.

  • Application / Software development

    Application / Software development

    Our customers are as individual as you are. No business and no process is like any other. To be able to implement processes across complex systems, you need to connect up software interfaces from the various systems in your infrastructure. This task is a particularly critical one in real-time communication and can often present a serious challenge to businesses.

    Over the years we have established a team of software developers with enormous experience in real-time communication to enable us to fully satisfy our customers’ needs. We create innovative solutions based on existing software architectures and interfaces by using agile software development methods. No matter how you want your solution to look, we can develop it – tailor-made to satisfy your demands.

  • Integration services

    Integration services

    Experience and expertise are essential factors for success in the technical implementation of any project. Our experts have large numbers of successful projects already under their belt and have enormous expertise in integrating complex ICT applications into broader ICT landscapes. In addition to the other services we offer, we can also provide you with an exhaustive range of ICT scenarios to allow you to explore the available technological opportunities to the full and to minimise project risk during implementation.

  • Rollout & field service

    Rollout & field service

    Before a system is ready for use, hardware has to be installed, cabling needs to be laid, patching needs to be done, work stations have to be connected up and devices need to be installed. Such tasks form a natural part of our service portfolio. We believe that providing such services is a vital part of delivering any key-in-hand solution! Only if everything is provided from a single source can you can be assured that no essential part of the task has fallen through the cracks.

    Wherever required, our rollout work is rounded off by our floor-walking service. Our floor walkers will patrol through your various departments after go-live and will provide any initial support users may need while getting used to the new system. We will always be pleased to help users with any query they may have on your applications. A satisfied user is a satisfied customer.

  • Training


    Training sessions form a routine part of WTG’s services. It is only possible to achieve the full speed and efficiency that your newly implemented systems are capable of if your administrators and users are trained properly in how to use and run them, not to mention motivated to take full of advantage of them. Designed both for groups and single trainees, our training sessions impart well-structured, relevant knowledge in easily understandable form on all subjects relating to our products. We provide all participants with the appropriate training materials. All training sessions combine hands-on practice with theoretical instruction.

Service Management

Our services allow you to focus on your core business – providing you with optimised ICT solutions that are completely robust and up-to-date.

  • Cloud services

    Cloud services

    Cloud services are getting an ever-firmer foothold in business. Much of the reason for the growth in such offerings is that it’s now no longer feasible for individual businesses to invest in standardized telecommunication techniques and on-premises solutions and operate them in-house.

    Free yourself of your own in-house hard- and software and increase predictability in the cost and effort required by your business communication into the future. WTG can provide you with all the right solutions to achieve this aim. Unified communications, collaboration and contact centre solutions out of the cloud – take advantage of the centralised services provided by our cloud platforms Comulus and WTG CLOUD. Our experts will provide all the support you need on your journey into the cloud.

  • Managed services

    Managed services

    The major challenges currently faced by today’s enterprises and IT organisations are centred on cost reduction, in parallel with the need to provide new services, stand-out features and high availability in today’s complex ICT landscapes. WTG’s ICT managed service portfolio has the capacity to square this circle. We can promise you that your costs will be calculable and your system environment be robust throughout the entire ICT system lifecycle. Through the customer-tailored managed services we offer, we can take over the management of your entire operations, up to and including taking full responsibility for assets and for outsourcing tasks.

  • 365/24/7 Service & support

Either on request or by contractual agreement, we provide a comprehensive service offering for every part of Germany and Europe, including remote servicing, hardware replacement and on-site service in case of system failure.

  • Proactive service

    Proactive service

    We consider the task of following up alert messages proactively before business processes are seriously affected to be a basic part of our service. We inform you of such problems promptly and proactively via our monitoring systems and intervene in good time to ensure the continued availability of your communication processes. The service we provide in the area of patch and release management ensures that the software on your systems is always up-to-date and conforms to your software suppliers’ life-cycle support processes. We take on full responsibility for your system environment, letting you focus on your core business!

  • Capacity & license management

    Capacity & license management

    Dynamic markets demand enterprise systems that can adapt quickly to new market conditions. With moves of location, expansions and new branch openings it’s very easy to lose track of how your IT infrastructure is developing – of what licenses and hardware you currently have and what you need to add to it. Server platforms, networks and firewalls may be gradually subjected to heavier and heavier loads. Continuous monitoring and maintenance of information on the utilization of systems and licenses can eat up a huge amount of time in IT departments. We can continuously, proactively and systematically monitor your hardware and software capacities for you and keep a check on how intensively you are utilising your licenses. This will prevent you from spending money unnecessarily simply due to lack of information.

  • Remote & on-site service

    Remote & on-site service

    The need to work on projects and at the same time provide speedy high-quality change services to specialist departments can be an enormous challenge to IT managers and administrators  – usually under conditions where manpower and expertise is at a premium. Our remote and on-site service will make the changes you require (IMACs) – at a flat rate cost where you need one. Many of our customers use this flexible service on an on-going basis, so that they can cover problematic periods effectively whenever necessary – during holidays, illness or project bottlenecks, for example – providing users in the various specialist departments with the quality in IT service that they are used to. We take the burden off you just when you need help most!
