XPhone Connect

Business communication software that adapts perfectly

Telephony software for enterprises and public institutions

Made in Germany. Secure by design.

For IT leaders who demand more than stand-alone tools: XPhone Connect unifies telephony, presence, CRM and hotline management in a single solution – customisable, seamlessly integrated and fully GDPR-compliant.


What XPhone Connect offers you

With XPhone you gain one solution instead of a jumble of tools. This UC platform restores simplicity to communication. From telephony and chat to hotline management, CRM integration, presence management and the mobile app – everything is combined within a single system. The result: a streamlined communications landscape and faster, more efficient processes.

XPhone fits smoothly into your existing IT environment – without forcing you into the cloud or tying you to a single vendor. Whether Cisco, Mitel or Alcatel-Lucent: your PBX remains, your systems remain – only communication becomes simpler.

At the same time, XPhone bridges the gap between legacy and modern technologies. Whether with a traditional PBX, no PBX at all or a hybrid set-up: you decide how your ICT infrastructure is designed.

Thanks to a Session Border Controller (SBC), migration with XPhone is gradual and non-disruptive, tailored to your individual requirements. You benefit from maximum flexibility: existing systems continue to run reliably, while new components integrate seamlessly. You keep full control over your communications environment whilst enjoying all the advantages of a modern UC solution.

And if today – or tomorrow – you wish to operate entirely without a PBX? XPhone is ready.

Supported PBXs

Use XPhone without a PBX

With XPhone, you decide how and where to deploy: locally in your own data centre or within a private cloud. Your communications data, presence information and call content remain entirely under your control.

XPhone meets all the requirements for secure, transparent and auditable operations. You retain full sovereignty over both infrastructure and data. The entire solution is fully GDPR-compliant.

This makes XPhone particularly suitable for public administrations, municipal IT service providers, critical infrastructures and data-sensitive organisations with stringent compliance needs.

Do you have specific requirements or complex workflows? XPhone Connect is designed to adapt to your organisation – not the other way around. Even complex scenarios and exceptions can be modelled.

Whether custom CRM fields displayed directly in the client, tailored call distribution or dynamic hotline management: XPhone grows with your needs. Your teams no longer need workarounds – they work with a solution that integrates seamlessly into established processes and actively enhances productivity.

UCC features

to suit your needs

The features of XPhone Connect were not developed in isolation but in close collaboration with our customers and partners. We listen and create solutions that deliver genuine added value. Whether ease of use, deep integration into existing systems or intelligent automation: discover the most popular features of XPhone and find inspiration for how you can transform your communications landscape.

Modern communication means connecting your communication directly with your most important business tools.

Thanks to deep integration with CRM, ERP or groupware systems, XPhone Connect displays all relevant information immediately during a call: customer name, status, order history, open tasks – directly in the client.

Sales can act immediately, support can provide targeted assistance, and customers feel well looked after.

Discover the XPhone Dashboard

Whether in the office, at home or on the move: with the XPhone softphone and mobile app you are fully equipped to work – even without a desk phone. Business chat with colleagues, presence synchronisation and hotline management all work seamlessly both on desktop and via the XPhone app.

Wherever you make a call, your office number remains visible and call quality is preserved. Presence status ensures colleagues always know whether you are in a meeting or available.

Discover Softphone

We apply artificial intelligence only where it delivers real added value – without compromising data protection and always in line with the highest compliance standards. For example, in call recording: XPhone converts phone calls into text, particularly relevant for call centres and other telephony-intensive departments.

Manual documentation is no longer required, and all call content is available in a structured format. This enhances customer service, increases team efficiency and provides a transparent basis for analysis and coaching.

Discover call recording

Who is available? Who is on a call or in a meeting via MS Teams, Zoom and others? With presence synchronisation, Microsoft Teams integration and the Team Panel, colleagues can see immediately – without having to ask.

With features such as business chat, presence management and screen sharing, a communications channel becomes a true teamwork tool.

All XPhone features at a glance

If contact centre solutions are too complex or inflexible for you: with XPhone Connect and the integrated hotline tool TeamDesk you can manage reachability intelligently, intuitively and across locations.

Whether internal helpdesks, central numbers or external hotlines: calls are distributed automatically and efficiently. Agents can log in easily, whether in the office, at home or on the move.

The Analytics business intelligence tool provides all relevant data to optimise reachability. This enables you to deploy resources proactively and handle peak loads effectively. Only when you know exactly when and where bottlenecks occur can you plan staffing optimally and at the same time improve productivity and service quality.

Go to hotline management

With the XPhone Connect mobile app you turn your smartphone into a full extension. Make calls, chat, access contacts, start meetings – everything in one app, always under your business number.

Whether on the train, in a hotel or working from home: you communicate just as comfortably as in the office. Thanks to the softphone you make calls worldwide via Wi-Fi or mobile network.

All contacts from ERP, CRM or Outlook are available on mobile in compliance with data protection – as are presence status, chat history and voicemail. The app integrates seamlessly into your communications infrastructure and supports modern workplace concepts such as Bring Your Own Device, without security risks.
