C4B Developer Programm

Platform-independent solutions


C4B offers you an efficient platform enabling you to integrate your software in your customers’ communication infrastructure with the aim of combining processes, applications and communication.


Registered designers receive from C4B the entire XPhone Connect platform free of charge enabling them to test how their software works with XPhone Connect.


Once tests are completed on your integration into XPhone Connect software, we actively support you in marketing your solutions which we then include on our Website for certified solutions.


The right offer for any customer

What does your business model look like?
Sell or lease your software, or offer it as a
service from the cloud. XPhone solutions adapt to your customers’ requirements.


For your customers who wish to use services entirely from the cloud without having any special infrastructure expertise or an obligation to host them.


For your customers wishing to use professional applications but commissioning a service-provider to operate the infrastructure.

On Premise

For customers who wish to retain full control of their own ICT infrastructure as well as host it themselves


The right platform for designers


Flexible solution

The XPhone software can be connected to practically any telco system and integrated in numerous business applications, even across several locations and PBX systems.

Low operating costs

One key criterion when selecting software is represented by low operating costs (TCO). XPhone software not only offers an intuitive, web-based administration interface – it can also be installed in no time at all and can be easily and swiftly configured.

Competitive advantages

A cross-platform solution ensures extensive market access as it works with practically all communication systems. Accordingly, you do not need to adapt your solution for each individual telco system and maintain it over the long term.


Market-leading software

The XPhone platform means you rely on market-leading standard software which requires minimum programming and which can be used for any customer. More than 1 million licences sold and thousands of satisfied customers speak a very clear language.

All companies

Whether for a small, medium-sized or large company, XPhone enables you to supply each customer with an individual communication solution based on a standardised platform. The software is multilingual which means you can even supply international customers with complex and heterogeneous infrastructures.

Basic licence model

Only the services and number of users are licenced which are actually required. In combination with your solution, the software can be used as a comprehensive UC system or for individual areas (CTI, fax, voicemail etc.).


Benefits for your customers


Improved communication

XPhone makes it possible to integrate all communication channels in applications and corporate processes, thereby improving communication.

Secure investment

Existing ICT infrastructures can be extended to include additional communication services in order to improve the added value of existing systems.

Low infrastructure complexity

All communication channels run centrally on a single server which can also be managed centrally.


Standardised UC solution

A standardised UC solution which can be used across several locations even if a different PBX system is available at each location

Scalable solutions

Scalable platform which can continue to be used even when subject to strong growth

Fast ROI

XPhone is easy to operate and manage, and can be up and running company-wide in only a short time. More efficient communication saves time and streamlines processes within the company.


Architecture and networking

Cross-platform, scalable and very innovative

XPhone Unified Communications solutions can be seamlessly integrated in existing IT landscapes and support all recognised ISDN- and IP-based telephone systems. Installation and connection is fast and easy. XPhone links various TC systems or locations to form a uniform communication solution for the entire company. XPhone solutions can be virtualised and used in terminal-server as well as in 32- and 64-Bit environments. Open interfaces permit seamless integration in existing ICT infrastructures as well as cross-platform application which is independent of individual manufacturers.
