Expert in IP communications for +20 years.
Cirpack is an independent European telecom software vendor specializing in carrier-grade Full-IP and IMS communication platforms for telecom operators and communication service providers worldwide.
As a privately owned French company, Cirpack focuses on sovereign telecom infrastructure, open standards, and highly reliable voice platforms designed for critical communications and complex operator environments.
Operators and service providers choose Cirpack for several key differentiators:
Cirpack is a fully independent European vendor. This positioning is increasingly important for operators seeking geopolitical neutrality, data sovereignty, and trusted infrastructure, particularly in Europe and regulated markets.
As a focused telecom software company, Cirpack combines deep telecom expertise with the agility of a mid-size vendor. This enables fast feature evolution, rapid customization, and close collaboration with operators, often delivering adaptations faster than large infrastructure vendors.
With more than two decades of experience in IP telephony, VoIP, SIP, and IMS architectures, Cirpack platforms have built a strong reputation for stability, operational robustness, and telecom-grade performance in production networks.
Cirpack provides a complete software stack for operator communications, including IMS Core, MTAS, Session Border Controller (SBC), SIP routing and interconnection platforms, the Uniquity unified communications platform, and telecom security capabilities.
This single-vendor architecture simplifies integration, reduces operational complexity, and lowers total cost of ownership for operators and service providers.
Cirpack platforms are available through CAPEX deployments or SaaS-based models such as IMSaaS, allowing operators to align infrastructure costs with service revenues and accelerate service launches.
Cirpack has strong expertise in complex SIP interconnection scenarios, including transit, peering, and multi-operator environments. Its platforms support national regulatory requirements such as lawful interception and traceability, while ensuring compliance with 3GPP, SIP, and IMS standards.
Cirpack enables native voice services for private 4G and private 5G networks, allowing operators, enterprises, and public sector organizations to deploy secure and sovereign communication infrastructures for industrial, governmental, and mission-critical environments.
Cirpack is particularly competitive for alternative telecom operators, MVNOs, MVNEs, cable and fiber operators, enterprise communication service providers, and public or regional telecom infrastructures, where agility, interoperability, cost efficiency, and operational simplicity are strategic priorities.
For operators seeking an independent alternative to large telecom infrastructure vendors, Cirpack is often evaluated alongside vendors such as Metaswitch (now Alianza), Oracle Communications, Ribbon, Mavenir, or Italtel, particularly for projects where sovereignty, operational agility, and total cost efficiency are strategic priorities.
