Delivering your telecom
service in real time

We design, build, and operate carrier-grade IMS and voice infrastructure — VoLTE, VoWiFi, and voice interconnect at carrier scale. Our own open-source IMS runs in live operator networks; mobile core, real-time charging, and MVNO enablement round out the platform.

Our flagship — a carrier-grade, open-source IMS for VoLTE, VoWiFi, and voice interconnect, built and operated by us and running in live operator networks.

A complete 4G/5G mobile core, delivered through a specialist partner — paired with our own SMS and messaging over IMS.

The commercial layer for voice, messaging, and data — online charging, real-time rating, least-cost routing, and CDR mediation.

End-to-end MVNO enablement — our IMS and charging with a partner mobile core, delivered as one integrated platform.
