Vodafone Ireland TOBi AI-Powered Virtual Assistant — 100K Interactions/Month with 60% Resolution

Vodafone Ireland's TOBi virtual assistant — built in partnership with Celfocus — now handles an average of 100,000 customer interactions per month with 60% full resolution and 99.9% uptime, while cutting agent handovers and direct call-centre costs by €42,000. Per the Celfocus case study: "Vodafone partnered with Celfocus to create TOBi, a virtual assistant that offers a comprehensive set of features designed to enhance customer interactions and streamline operations" — split into two fully automated AI agent systems designed to directly assist customers. Vodafone Ireland sought to transform its customer-service landscape by deploying a natural-language model that could accurately identify customer intentions, deliver rapid responses, and sustain uninterrupted conversations — including for users who traditionally interacted with human agents. The old way was human-agent-only customer support, which couldn't scale to digital-channel demand. The project was built using a micro-modular strategy, with frontend, AI, Java business logic, VoIP, gateway, speech-to-text/text-to-speech, and Tele Management Forum (TMF) modules delivered by separate teams under the TOBi structure. The deployment integrates with the TMF Digital experience layer, contributing to the development of 10+ TMFs and the enhancement of 50+ others. Architecture: two fully automated AI agent systems handle automated customer care, troubleshooting, and e-Shop functionality, with natural-language interaction across both voice and chat channels. End-to-end stack: micro-modular design — frontend + AI + Java business logic + VoIP + gateway + STT/TTS + TMF modules; integration with the TMF Digital experience layer enables knowledge sharing across digital channels. Operational scale: 100,000 interactions/month; 60% full resolution rate; 99.9% uptime; €42,000 reduction in agent handovers and direct call-centre costs. Operational across voice and chat channels with continuous availability. Knowledge contribution: 10+ new TMFs developed, 50+ others enhanced. The case study positions the architecture as "internally reusable within Vodafone Ireland and across other Vodafone opcos" — designed for replication to additional Vodafone markets beyond Ireland.
