18 March 2026, Sofia – Paris: CallFactory, a leader in the telecom industry offering international phone numbers and fully programmable IVR systems to businesses across Europe, announces a strategic partnership with Linphone, the leading open-source softphone provider for desktop and mobile communications.
This partnership responds directly to a growing demand from larger corporations and public-sector organisations for communication solutions that are secure, verifiable, and easy to deploy at scale. As operational environments rapidly become digitalised, this partnership offers enterprises the opportunity to combine transparent, auditable software with a reliable European telephony infrastructure.
Organisations gain full visibility into the software they install, maximising usability and cross-platform availability. As concerns around security, compliance, and digital sovereignty continue to rise, many enterprises are re-evaluating the tools they use for voice communications. A key requirement is the ability to inspect, validate, and trust the software running on employee devices.
Linphone allows organisations to review the source code and understand exactly how the application functions. This makes Linphone particularly attractive to larger enterprises, regulated industries, and organisations with strict internal security policies.
CallFactory complements this approach by providing European telephone numbers and voice services that completely integrate with Linphone. Together, the platforms offer a secure, standards-based communication solution that aligns with European data protection, openness, and control guidelines.
Main Advantages of the Partnership
Broad platform support: Modern enterprises operate across multiple devices and operating systems, and softphone solutions must be flexible enough to match this reality.
Consistent communication experience: Linphone supports all major desktop and mobile platforms, including macOS, Windows, Linux, iOS, and Android, ensuring organisations can deploy a consistent communication experience regardless of device.
No proprietary restrictions: With CallFactory providing the underlying telephone numbers and voice connectivity, users can make and receive calls directly through Linphone on any supported platform, without vendor lock-in.
Simple, Scalable Deployment via QR Code
Ease of deployment is another key focus of the integration. Rolling out communication software to dozens or hundreds of users is often complex and time-consuming. This integration simplifies the process through QR code-based provisioning, allowing users to install and configure their softphone with a single scan, reducing the likelihood of configuration errors.
This approach makes the solution suitable not only for large enterprises but also for organisations that need to rapidly scale their communications infrastructure.
A Future-Proof Communication Solution
By combining open-source software, cross-platform support, and European telephony services, Linphone and CallFactory deliver a resilient solution designed for organisations that value clarity, flexibility, and control. The integration empowers enterprises to adopt modern softphone technology while maintaining oversight of the software they deploy and the infrastructure they rely on.
Our customers are looking for a high-end solution that is secure and allows them to inspect the source code to ensure that what they are installing aligns with company policies — Linphone offers that. Where the softphone really shines — on a desktop as a replacement for desk phones — Linphone has full support for Mac, Windows, and Linux.
We are delighted to partner with CallFactory. By pairing our softphones with their extensive international numbering, we are providing a powerful, seamless solution for businesses worldwide. We look forward to welcoming CallFactory's customers to the Linphone ecosystem.
