NFON and O2 Telefónica Deutschland are continuously developing their strategic partnership, and now NFON AG, a leading European provider of integrated business communications with a focus on AI-based applications, has reached an important milestone together with O2 Telefónica Deutschland.
By the end of 2025, more than 100,000 users at O2 Telefónica Deutschland’s business customers were utilising the cloud-based Digital Phone business telephony solution based on NFON’s cloud telephony platform. Digital Phone is deployed by companies in key economic sectors, including industry, retail, logistics and the public sector.
Modern Communication Solutions
Digital Phone enables companies to manage their business communications independently of location and device via desk phones, mobile devices and web applications, thereby forming the foundation for modern, integrated business communications. Companies benefit from a centrally managed, flexibly scalable communication solution that can be integrated into existing IT and process landscapes and supports both location-independent working and efficient collaboration in distributed teams.
The collaboration represents a long-term partnership in which technological expertise, market access and operational scaling are brought together. O2 Telefónica’s strong market position and sales organisation, combined with NFON’s many years of experience in operating cloud-based business communication solutions, make it possible to reliably address companies of all sizes.
Partnership built for Scaling
While O2 Telefónica Deutschland has historically focused primarily on small and medium-sized enterprises, the joint customer focus is increasingly shifting toward multinational customer structures and larger enterprise organisations.
The user volume achieved with O2 Telefónica Deutschland highlights the scalability of NFON’s wholesale model and underscores the partner’s importance for the development and growth of the wholesale business. O2 Telefónica Deutschland ranks as one of NFON’s most significant wholesale partners. In addition, NFON works in the segment with other well-known providers such as Deutsche Telekom and 1&1 Versatel.
Andreas Wesselmann, Chief Executive Officer of NFON AG, comments:
“Our partnership with O2 Telefónica Deutschland stands for stability, scalability and genuine trust established over many years. Together, we enable companies to adopt modern, integrated business communications that flexibly adapt to their requirements and grow with them. It is precisely this combination of technological strength and reliable cooperation that makes our model successful. With NFON Next 2027, we are consistently building on this foundation – with clear commercial structures and a selectively expanded AI-based solution portfolio.”
Growth in Cloud Telephony
To date, the growth of the partnership has been driven primarily by cloud telephony. Building on this, the wholesale offering will be gradually expanded to include AI-based applications across the NFON product portfolio in order to further address market demand and unlock additional growth potentials.
This includes applications in the areas of Business Telephony, Intelligent Assistant and Customer Engagement: while Business Telephony serves as the technological foundation, the Intelligent Assistant area includes, among other products, automated chat and voice bot solutions for handling recurring inquiries.
The Customer Engagement area comprises contact centre solutions that route inquiries across channels to the right contacts and support employees in handling customer requests efficiently and in a targeted manner.
Mallik Rao, Chief Technology & Enterprise Officer at O2 Telefónica Deutschland, notes:
“The NFON Digital Phone solution forms an integral part of our business communications portfolio. The milestone we have achieved confirms the sustainable success of our partnership and creates a solid foundation for gradually expanding our offering with AIbased applications, thereby generating additional value for our business customers.”
