Real Time Telecom B.V.

Over Real Time Telecom B.V.

Real Time Telecom designs, builds, and operates carrier-grade telecom infrastructure. From 4G/5G mobile core networks to production SIP/IMS voice platforms, we power voice, messaging, and connectivity for operators and MVNOs at scale.

Built for operators, by operators. We were founded on 15+ years of hands-on experience running telecom infrastructure at carrier scale.

What we do: • Mobile Core & Messaging — 4G/5G core networks plus SMS infrastructure (SMSC, IP-SM-GW, SMPP), engineered in Rust for carrier-grade performance. • IMS & Voice — production SIP/IMS infrastructure: VoLTE, VoWiFi, WebRTC, call recording, and carrier interconnect. • Real-Time Charging & BSS — online charging (OCS), real-time rating, least-cost routing, and CDR mediation. • MVNO Solutions — end-to-end enablement, from complete mobile core to voice, messaging, and real-time charging.

Why operators choose us: • Production proven — built and battle-tested in live carrier networks, not in the lab. • Deep protocol expertise — SIP, Diameter, SS7/MAP, GTP, SMPP, PFCP — built from the ground up in Rust. • Open-source commitment — Siphon, our SIP/IMS platform, is MIT-licensed with 1,500+ automated tests.

Engagement models: managed platforms, consultancy & fractional CTO, and custom development.

Let's build telecom that performs in real time. 🌐 realtime-telecom.nl ✉ sales@realtime-telecom.nl
