Cloud-native voice & core networks

VoLTE, VoNR & VoWiFi,
built for the cloud era

Cloud-native telecom software for MNOs, MVNOs, private network and mission-critical operators — from the flagship IMS core (VoLTE/VoNR) and ePDG (VoWiFi) to mobile core, HSS and SMS functions, all built from scratch in Golang.

Most IMS cores on the market were designed 20 years ago — and cannot fulfil today's network, deployment and operations requirements. Ours is designed for them.

Products

Everything built in-house in Golang. Cloud-native, zero legacy — designed for this decade, not the nineties.

THE FLAGSHIP

Scalable Voice

3GPP IMS core — P-CSCF, S-CSCF and I-CSCF, Release 19, with the latest encryption algorithms — plus E-CSCF/IP-SM-GW, SBI adaptor, IPsecProxy and Supplementary Services AS.

VOICE WITHOUT COVERAGE GAPS

Wi-Fi Calling Gateway

Standard ePDG for VoWiFi — in simplified mode or 100% standards-compliant mode. Built on our own user-space IPsec implementation, which outperforms and out-flexes kernel-based stacks.

THE PACKET CORE

Scalable Mobile Core

PGW-C/SMF + UPF with gtpProxy — a lean mobile core for MVNEs, MVNOs and MNOs, designed to scale from small private networks to national footprints.

DIAMETER DONE RIGHT

HSS & DRA

DRA / DEA — a dual-role Diameter Routing and Edge Agent: subscriber data, routing and edge policing in one lean component.

MESSAGING

SMS & Messaging

IP-SM-GW, SMSC, SMSF and MMSC — modern messaging functions that integrate cleanly with our IMS core and mobile core. Ask us for details.

Voice as a Service

VaaS — our voice layer offered as a fully managed service. Watch this space, or ask us about early access.

Proven in real networks

Standards compliance is the entry ticket. What proves a voice core is what it does next to other vendors' equipment and real handsets.

MULTI-VENDOR INTEROP

Integrated with other vendors' networks

  • Real interworking with packet cores, HSS and IMS functions from other vendors — including Tier 1 suppliers.
  • Drop-in capable — our functions integrate into existing multi-vendor landscapes, not just greenfield builds.
  • Tested against real handsets across device ecosystems, not only lab simulators.
ENGINEERING EDGE

Own implementation, no inherited limits

  • User-space IPsec written from scratch — better performance control and flexibility than kernel-bound stacks.
  • Latest encryption algorithms throughout, kept current with Release 19.
  • Golang codebase — memory-safe, observable, easy to extend and upgrade.
MISSION-CRITICAL

The IMS behind MCX and FRMCS

  • Standards-compliant MCX requires an IMS — the same applies to FRMCS for rail. There is no mission-critical calling without one.
  • Chosen by MCX vendors — several MCX vendors build on our IMS core, because it is a standard IMS, done properly.
  • Built for critical use — the reliability and correctness mission-critical communications demand.
