Partnering with Kahea AI to power next-generation voice infrastructure
Kahea AI delivers enterprise-grade conversational AI on DigitalFrontier Core — VoIP load balancing and multi-cloud orchestration at 99.99% uptime and sub-50ms latency.
We're announcing our partnership with Kahea AI, a pioneering force in conversational AI and intelligent IVR systems. Kahea AI runs their mission-critical voice infrastructure on DigitalFrontier Core, handling thousands of concurrent calls with enterprise-grade reliability.
The challenge: voice infrastructure at scale
Voice applications demand infrastructure that traditional cloud platforms struggle to deliver. Every millisecond of latency impacts customer experience. Any service disruption means dropped calls and frustrated users. As Kahea AI scaled their platform to handle enterprise customers, they needed:
- Sub-50ms latency for real-time voice processing
- 99.99% uptime with automatic failover
- Geographic distribution to minimise latency worldwide
- Cost optimisation without compromising reliability
The solution: multi-cloud VoIP load balancing
Kahea AI deployed DigitalFrontier Core to orchestrate their VoIP infrastructure across multiple cloud providers.
Intelligent load balancing
Core's VoIP load balancer automatically routes voice traffic based on:
- Geographic proximity, to minimise latency
- Real-time health checks and automatic failover
- Load distribution across multiple regions
- SIP and RTP protocol optimisation
Multi-cloud architecture
The platform leverages:
- GCP for primary production workloads with enterprise reliability
- The DigitalFrontier Edge for cost-optimised regional capacity on hardware we own and operate in Europe
- Akash Network for decentralized burst capacity during peak loads
Service-mesh networking
A Consul-based service mesh provides:
- Automatic mTLS between all services
- Service discovery across regions
- Traffic management and circuit breaking
- Observability and distributed tracing
The results
Since deploying DigitalFrontier Core, Kahea AI has achieved:
- 99.99% uptime with automatic failover across regions
- <50ms average latency through intelligent geographic routing
- 60% infrastructure cost reduction via multi-cloud optimisation
- 5× faster deployment — from days to hours for new regions
DigitalFrontier Core transformed our VoIP infrastructure. The intelligent load balancing and multi-cloud orchestration give us the reliability we need for voice workloads, while significantly reducing our infrastructure costs. The automatic failover has saved us countless times.

What this means for voice applications
This partnership demonstrates Core's capability to handle the most demanding real-time workloads. Voice infrastructure requires consistent low latency — any spike disrupts conversations. It requires high availability, with no room for downtime during business hours. It requires global distribution, because users expect local performance everywhere. And it requires cost efficiency, because voice traffic volumes get expensive fast.
Core delivers on all four, which makes enterprise-grade voice infrastructure reachable for companies of any size.
Looking forward
We're excited to see how Kahea AI continues to push the boundaries of conversational AI. Their success validates our thesis: multi-cloud orchestration shouldn't force a compromise between performance, reliability and cost.
If your team is building voice applications, real-time services, or any latency-sensitive workload, we'd like to show you how Core can help.
