Working with volte.io

Operators and providers integrating volte.io into their networks

Complete core
With volte.io we run our complete core — IMS, EPC, and VoLTE/VoWiFi — on a fully cloud-native platform. For an operator of our size that was exactly the point: the functional depth of a carrier-grade core without the cost structure of the traditional vendors. You talk to the people who actually build the platform.
Christos Omirides CEO, Telco-Village
ePDG and VoWiFi
We integrated volte.io’s ePDG and AAA server for our VoWiFi service. Findings from our lab were typically addressed within days, and our own patches were reviewed and merged just as quickly. We have full access to the source code — trust that goes both ways.

LoST and HELD emergency call routing: the IMS core retrieves the caller's location from a LIS via HELD and asks an ECRF via LoST which PSAP serves that place, delivering the emergency call to the right call taker

LoST and HELD: How an Emergency Call Finds the Right PSAP

Routing an ordinary call is a question about a number. Routing an emergency call is a question about a place. How HELD and LoST answer the two questions behind NG112 routing – and why a failed lookup must never fail the call.

ePDG update built for real devices and real operations: iPhone and Samsung handsets connecting over VoWiFi from home, office, and on the road through the volte.io ePDG and AAA server to the IMS core

ePDG Update: Built for Real Devices, Real Operations

Weeks of hardening against commercial handsets. EAP-only IKEv2 for operators without a certificate in the manufacturers’ trust stores, a datapath whose kernel footprint does not grow, and restarts that keep calls up.

Why VoLTE does not work without Rx or N5: IMS connected to the transport network through the Rx and N5 policy interface so the RAN can protect conversational voice under load

Why VoLTE Does Not Work Without Rx or N5

One call on an idle cell proves signalling, not a voice service. Rx and N5 are how the IMS tells the radio that speech is in progress – without them, the busy hour is where the service fails.
