Some of our clients were sure all the way through to the end of the call that they weren't speaking with an AI at all, despite us clearly stating multiple times before and during the conversation that they were interacting with an AI.
Marc — Viessmann
Outstanding young team with an incredibly fast pace of implementation, quick comprehension, and high responsiveness to feedback
Yannick — Termios
The voice AI calls customers and schedules (or directly forwards) appointments with our kitchen planners. This is extremely time-efficient, since the planners can focus on more important tasks.
Richard — KitchenAdvisor

Linda — McMakler
We’ve been using telli for three months to book appointments with leads, and the results have been great. It’s surprisingly easy to use, and the AI agent consistently books appointments at the same rate or better than our internal call center.
