Three proven core engines. One accountable engineering partner.
4G / 5G Converged Core
Full EPC and 5G Standalone (5GC) function set engineered for high-throughput, converged mobile networks. Scalable from single-node private wireless pods up to high-capacity, containerized operator cores powering turnkey network builds.
Explore 4G/5G Core →Carrier IMS & VoLTE Core
Enterprise-hardened VoLTE, VoNR, and VoWiFi voice core. Kamailio has routed Tier-1 operator SIP traffic globally for twenty years—we package and interconnect it into a resilient, highly concurrent IMS voice engine.
Explore IMS Core →2G / 3G Packet Core
Ultra-reliable, lightweight legacy packet core specifically optimized for massive M2M IoT estates, rural cellular connectivity, and controlled 2G/3G sunset transitions—with a seamless bridge to our LTE/5G core.
Explore 2G/3G Core →Hosted 4G / 5G Core SaaS
Our fully hosted, turnkey mobile core for MVNOs, enterprise labs, and private wireless pilots. Access our hardened Open5GS platform as a service via nfvi.io—simply connect your eNodeBs/gNodeBs, load your SIMs, and skip the server overhead.

Legacy proprietary core vendors force you to trust an expensive black box while taxing your growth with recurring per-subscriber license fees. We take the exact opposite approach: the software code is 100% open, auditable, and free of subscriber taxes. Our commercial value is turning that code into an SLA-guaranteed, carrier-grade powerhouse.
- $0 per-subscriber license taxes — grow from 1,000 to 1,000,000 subscribers without paying a single cent more in software licensing.
- Zero vendor lock-in — because the underlying platform is open source, your infrastructure remains permanently yours. If we ever stop earning your trust, your core keeps routing traffic.
- Complete regulatory auditability — you and your national telecom regulators can inspect every single line of C code that processes subscriber packets.
- Global community velocity + commercial SLA — harness upstream innovation from thousands of global developers, backed by guaranteed 15-minute response times from dedicated Srianu principal engineers.
What "Production-Hardened" Means at Srianu
Every carrier release we ship is rigorously engineered:
- Version-pinned, stress-tested, and verified against strict 3GPP interface specifications
- Security-hardened to eliminate vulnerabilities and comply with carrier deployment baselines
- Fully automated via Ansible/Helm for instant, repeatable bare-metal, Proxmox, or Kubernetes deployments
- Pre-instrumented with Prometheus and Grafana for real-time telemetry and predictive capacity management
- Protected 24×7×365 by our direct commercial support tiers
Choose the cover your network needs.
Every tier includes our packaged builds, deployment automation and access to Srianu core-network engineers — not a first-line script.
