The two French vendors are combining mobile core and IMS expertise to simplify deployment of private 5G networks with carrier-grade voice services for industrial users
CIRPACK and Halys have announced the integration of their respective platforms to deliver a private 5G solution with native Voice over New Radio (VoNR) capabilities, targeting industrial and enterprise environments that require both high-performance data and carrier-grade voice.
The partnership brings together Halys’s operator-grade 5G standalone (SA) core software with CIRPACK’s IP Multimedia Subsystem (IMS) telephony platform, enabling private networks to support native 5G voice services without relying on legacy circuit-switched infrastructure or public-network architectures.
Private 5G deployments have largely focused on data-centric use cases such as automation, video analytics and IoT connectivity. However, voice remains a critical operational requirement in sectors including manufacturing, healthcare, transport and energy, where low-latency, reliable team communications are central to safety and coordination.
Until now, integrating full telephony capabilities into private 5G environments has typically required complex multi-vendor architectures or solutions originally designed for PSTN. CIRPACK and Halys reckon that their combined approach provides a more compact and right-sized alternative.
Halys provides a fully software-based 5G SA core designed for on-premises, edge or cloud deployment, giving enterprises control over data flows, access policies and network operations. The company has positioned its platform around sovereign and independent deployment models, a theme it reinforced in February 2025 through a validation partnership with Emblasoft to independently test and verify its 5G SA core for private network use cases.
CIRPACK contributes a virtualised IMS platform delivering SIP-based telephony services including HD voice, video and VoWiFi, already deployed by more than 120 fixed and mobile operators across 24 countries. By integrating IMS directly with the 5G core, the joint solution supports native VoNR within a fully 5G architecture.
Standards-based
Both platforms are designed to comply with 3GPP standards as well as GSMA and ETSI frameworks, enabling interoperability across private and public 4G/5G environments. The vendors say this standards alignment allows enterprises to integrate private deployments with national operator networks and evolve towards future network generations without major architectural changes.
The combined offer is positioned around Industry 5.0 principles – side note, there are almost as many “Industries” as Gs in mobile – with an emphasis on resilience, human-centric operations and digital sovereignty. Key elements include native, carrier-grade voice embedded within the 5G architecture, enhanced security functions such as authentication and topology protection, and lightweight virtualised deployment models intended to reduce infrastructure complexity and cost.
CIRPACK chairman and chief executive Patrick Bergougnou said the partnership reflects a belief that next-generation private networks must combine security, flexibility and voice capabilities while being built on European technology foundations.
Halys chief executive Samuel Dralet added that as private 5G adoption accelerates across Europe, enterprises are seeking resilient and sovereign infrastructure models rather than relying solely on global equipment vendors.
The deal is a sign that private 5G is finally graduating from the proof-of-concept classroom. Enterprises no longer want a network that can carry data; they want one that won’t flinch when a factory floor goes quiet or a distress call needs to get through. For European vendors, it is also a quiet declaration of independence: software-defined, sovereignty-first cores are muscling into the digital infrastructure arguments. Here’s hoping the next step is policy.
