ePDG Gateway

Wi-Fi Calling Gateway

A standard ePDG for VoWiFi — in simplified mode or 100% standards-compliant mode — built on our own user-space IPsec implementation. Wi-Fi calling that closes coverage gaps and takes the sting out of roaming.

THE GAP IT CLOSES

Coverage where your radio isn't

VoWiFi everywhere — indoor coverage and international roaming over any Wi-Fi, terminated in your own network.
SMoW support — messaging over Wi-Fi alongside voice.
Your mode of choice — a simplified mode for fast launches, or 100% standards-compliant operation for full interworking.

THE ENGINEERING EDGE

Our own user-space IPsec

Written from scratch — not bound to a kernel implementation, so performance and behaviour are ours to control.
Better control — per-session tuning, observability and upgradeability that kernel-bound stacks can't offer.
IKEv2 with the latest encryption algorithms — kept current with Release 19.

Works well with Scalable Voice Scalable Mobile Core
