What Cirpack does

Cirpack is a French telecom software company founded in 1998 that builds carrier-grade IP Multimedia Subsystem (IMS), Session Border Controller (SBC), and Next Generation Network (NGN) softswitch platforms for fixed and mobile operators, MVNOs, and service providers. Its technology stack is fully virtualized, cloud-native, and hardware-independent, supporting SIP-based voice, video, and messaging across VoIP, VoLTE, VoWiFi, and VoNR deployments, with compliance to 3GPP, GSMA IR.92/IR.51, ETSI, and ANSSI standards. The product portfolio spans a complete SIP service chain — IMS core, SBC, Telephony Application Server, portability/number routing, STIR/SHAKEN caller authentication, and the Uniquity enterprise UCaaS platform — together with IMSaaS, a fully managed cloud-hosted IMS offering.

Cirpack monetizes through a mix of one-time software licenses (CAPEX), recurring IMSaaS subscriptions priced per subscriber per month, Uniquity SaaS billed through partner operators and resellers, and professional services including 24/7 NOC support and dedicated SPOC engineers. Go-to-market combines direct enterprise sales for major operators with a Value-Added Reseller network for mid-market reach, supplemented by the IMSaaS cloud platform which supports self-service deployment. The company employs 51-100 staff across offices in France (Issy-les-Moulineaux), Tunisia, Vietnam, and Mexico.

The installed base includes more than 120 operator customers across 24 countries in Europe, Africa, and Latin America, serving 60 million+ end users and processing 10 billion+ communications annually. Named customers include Bouygues Telecom, Free, SFR, OVHcloud, Tigo, Canal+ Groupe, Coriolis, Salt, Eir, TIM, and Spie Batignolles. Recent strategic partnerships with Halys (private 5G VoNR) and Summa Networks (VoLTE for Vodafone Polynésie) signal expansion into industrial private networks and new geographies. The company raised approximately $3.3M in 2015 from Bpifrance and M Capital Partners and is privately held under long-tenured CEO Patrick Bergougnou.

Revenue model

1. Software Licenses: Traditional CAPEX model where operators purchase software licenses for on-premises deployment of IMS, SBC, NGN, and other platforms. Licenses are sold based on subscriber capacity and feature modules.
2. IMSaaS (IMS as a Service): Fully managed cloud-native IMS core network delivered as a hosted service with OPEX-based pricing. Charged per subscriber per month including SLA, upgrades, 24/7 NOC monitoring, AI-driven capacity planning, and preventive maintenance. Features degressive pricing for higher volumes.
3. SaaS/Unified Communications: Uniquity platform offered as SaaS solution for enterprise telephony. Partners (operators, resellers) bill end customers monthly for service usage, creating recurring revenue streams with immediate profitability based on OPEX model.
4. Professional Services: Customer engineering, consulting, training, and 24/7 support services including SLA options with emergency assistance, issue analysis, software upgrades, and hardware replacement. One SPOC Support Engineer based in Paris per customer.

Broad incumbents

• Nokia: Nokia provides IMS core, Cloud Packet Core, and voice solutions as part of its AnyRAN/AVA portfolios. As a broad incumbent, Nokia competes with Cirpack in traditional operator deployments and increasingly in private 5G networks, where it bundles voice with radio and core.
• Oracle (Acme Packet): Oracle's Acme Packet SBC and session delivery portfolio competes with Cirpack's SBC offering in Tier-1 operator and large enterprise deployments. As a broad incumbent, Oracle bundles SBC with broader communications and cloud infrastructure offerings.
• Ericsson: Ericsson is a global incumbent telecom equipment vendor offering end-to-end IMS, VoLTE/VoNR core, and unified communications solutions. Competes with Cirpack primarily in Tier-1 operator tenders where integrated full-vendor offerings are preferred, often winning on incumbency and scale rather than agility.
• Microsoft (Metaswitch): Microsoft acquired Metaswitch in 2020, bringing cloud-native IMS, SBC, and VoIP capabilities into Azure. As a broad incumbent hyperscaler, Microsoft competes with Cirpack on cloud-deployed voice infrastructure for telecom operators and enterprises, leveraging cloud bundle economics.

Direct peers

• Dialogic: Dialogic provides SBC, media gateway, and signaling software for service providers and enterprises. Competes with Cirpack in SIP interconnection, SIP trunking, and carrier-grade softswitch markets with a similar software-only delivery model.
• Mavenir: Mavenir is a US-based telecom software vendor specializing in cloud-native IMS, VoLTE/VoNR, and SBC solutions for mobile operators. Directly competes with Cirpack in the carrier-grade software-defined voice core market with overlapping target customers (Tier-2/Tier-3 operators, MVNOs).
• AudioCodes: AudioCodes is a specialist vendor of SBCs, VoIP media gateways, and UCaaS/contact center voice infrastructure. Directly competes with Cirpack in SBC and enterprise voice markets, with similar positioning as an agile mid-market alternative to large incumbents.

Emerging players

• Alianza: Alianza is a cloud-native communications platform provider focused on UCaaS and VoIP for service providers. Competes with Cirpack's Uniquity offering in the cloud UCaaS segment serving broadband operators and ISPs transitioning away from legacy PBX.
• Summa Networks: Summa Networks provides HSS, HLR, UDM, and AUSF core network functions for mobile operators. Partners with Cirpack on the Vodafone Polynésie VoLTE deployment, with adjacent/overlapping scope in mobile core but different functional specialization (subscriber data vs. IMS service layer).
• Halys: Halys provides operator-grade 5G core software platforms for secure and sovereign private mobile networks. Partners with Cirpack on private 5G/VoNR solutions, with adjacent offering for industrial/enterprise private networks that integrates with Cirpack's IMS voice layer.
