A French IMS specialist and a Spanish Mobile Core Network expert combine their technologies to deliver carrier-grade Voice over LTE services for a leading mobile operator in the South Pacific.
Paris, France – 13 April 2026
CIRPACK Software today announces the deployment of Voice over LTE (VoLTE) services for Vodafone Polynésie, in collaboration with Summa Networks, enabling the operator to modernise its voice infrastructure and deliver high-quality, standards-compliant VoLTE services across French Polynesia.
Serving approximately 150,000 subscribers across five archipelagos, Vodafone Polynésie, operated by Pacific Mobile Telecom, faces the challenge of delivering consistent connectivity across geographically dispersed islands. The transition to VoLTE marks a strategic step forward, enabling HD voice quality, faster call setup and simultaneous voice and data services over 4G networks.
The deployment combines CIRPACK’s fully software-based IMS telephony platform with Summa Networks’ modular mobile core, which already manages subscriber data for the operator. Together, the two technologies form a complete and right-sized VoLTE solution tailored to the needs of regional mobile operators, balancing performance, flexibility and operational efficiency.
CIRPACK’s IMS solution covers the full SIP service chain, from user authentication to service delivery, and supports VoLTE, VoWiFi and future VoNR services, scaling from small deployments to several million subscribers with a minimal infrastructure footprint. Summa Networks complements this with a cloud-native core supporting multi-generational networks from 2G to 5G, ensuring seamless service continuity and a smooth evolution path.
The integrated CIRPACK Software-Summa Networks solution is specifically designed for regional mobile operators that require carrier-grade voice services without the complexity and cost of solutions built for large-scale public networks. The solution brings together:
- Native VoLTE and VoWiFi services fully integrated within the LTE architecture, delivering HD voice quality and simultaneous voice and data capabilities
- Seamless subscriber data management across 2G, 3G and 4G technologies, ensuring service continuity during the transition to all-IP voice
- Built-in security mechanisms, including IMS-AKA authentication, topology hiding and SIP DDoS protection, designed to safeguard voice communications
- Lightweight, virtualised deployments that reduce infrastructure complexity and operational costs, making VoLTE accessible for operators of all sizes
- Standards-based interoperability with existing network elements and a clear evolution path toward VoNR (Voice over New Radio) for future 5G deployments
Patrick Bergougnou, Chairman and CEO of CIRPACK Group, said: “This collaboration with Summa Networks demonstrates the strength of European telecom innovation. Together, we are bringing carrier-grade VoLTE capabilities to Vodafone Polynésie, proving that right-sized, agile solutions built by European specialists can deliver the same quality as those offered by global equipment vendors — with greater flexibility and proximity to the operator’s specific needs.”
Javier Martín, CEO of Summa Networks, said: “Our long-standing relationship with Vodafone Polynésie and our expertise in subscriber data management make this VoLTE deployment a natural next step. By combining our mobile core platform with CIRPACK’s IMS telephony solution, we deliver a complete, integrated offering that enables the operator to modernize its voice services efficiently and cost-effectively.”
By combining their expertise, CIRPACK Software and Summa Networks deliver a sovereign, right-sized European alternative to large-scale solutions traditionally offered by global equipment vendors.
