Detailed Review
telli concentrates on customer-facing call operations: qualifying leads, reactivating dropped customers, booking appointments and handling service enquiries. The home page names Sky and 1KOMMA5° as customers and carries a banner about a USD 15 million funding round.
The company behind it is telli technologies GmbH, registered at the Charlottenburg court in Berlin.
Building and improving agents
telli Studio is a no-code builder where conversations are changed in natural text. An assistant called Charlie helps build agents, analyse calls and suggest improvements.
Agents can run actions in the middle of a call, and post-call workflows push results into connected systems.
Running calls at scale
Parallel calls scale from one line to thousands without staffing changes. Smart dialing tunes call timing and retries, and live monitoring shows every active call and agent.
Each call ends with outcomes such as summaries, sentiment and structured data, and reviewers can flag calls as pass or fail.
Telephony and languages
You can use telli numbers or bring your own through SIP trunking. The site quotes 20+ languages in one place and 30+ in another, with local accents.
Limitations to Consider
telli publishes no prices, so a budget needs a demo call. The language count differs between two places on the home page (20+ and 30+). The privacy policy we checked does not name hosting regions or sub-processors. It targets operations teams rather than hobby projects, so Famulor or fonio suit small budgets better.
Who Should Use telli
Sales and service operations that call many people and want an agent platform with CRM links and quality tooling.
