telli Reviews & Product Details

I really like the flexibility of Telli, as everything is very adjustable and there are great opportunities for testing. We receive very good feedback from the on-site team, which makes it a great tool to collaborate with. The onboarding process went very well, and it was pleasant that we were super flexible in setting the start time. The setup was super easy and the support was great, allowing our Sales Operations Manager to get started right away. Review collected by and hosted on G2.com.

The speed could definitely still be improved, but we were also very satisfied with the response. At the end of the day, everything is a development. So it's clear that it's not a tool that is 100 percent there from the start, because the AI also has to learn and be adapted to its requirements. Review collected by and hosted on G2.com.

The software is already mature and includes the relevant classic software‑service elements that are necessary. You can immediately tell that the team behind it takes very few shortcuts at most. On top of that, the voice bot naturally does what it’s supposed to do. In particular, the speed and interaction capabilities are definitely on par with Nvidia’s PersonaPlex, while the possible complexity and stability are significantly better. In addition, there’s a very professional team that apparently knows what matters. Review collected by and hosted on G2.com.

The versioning and potential organization within the prompt/context and sub-prompts Review collected by and hosted on G2.com.

The collaboration with Telli has noticeably changed our daily sales routine. Thanks to this great support, my team can focus much more on the truly relevant conversations and is significantly relieved in day-to-day business. Review collected by and hosted on G2.com.

So far, everything fits wonderfully, and I have nothing to complain about. Overall, I am very satisfied. Review collected by and hosted on G2.com.

The user portal to manage the agents and fill the script is very intuitive and user friendly.

Also the customer support they provide is quick and they like to think with you for solutions. Review collected by and hosted on G2.com.

There are no real downsides other then people that do not like to talk to AI, but that has nothing to do with Telli. Review collected by and hosted on G2.com.

What I like most is the quality of Telli. Better than any other telephony agent I have seen so far. And the ease of use. The initial setup was extremely easy, with a lot of support. This greatly facilitates getting started. Review collected by and hosted on G2.com.

Well, of course, the language function can always be improved so that it sounds even more like a human. Review collected by and hosted on G2.com.

I have been a customer of Telli’s for approximately 6 months now. In that time I have seen them consistently deliver new and impressive capabilities to their platform. Their support is very good; nothing has slipped through the cracks.

For context, I am the Head of Engineering at a start up in the United States. Given the technical nature of my work, what Telli has built and provided to its customers is astounding. I have the ability to spin up a new voice AI agent on demand and refine its persona with just a few keystrokes.

The _velocity_ that I can move with for voice AI agent needs is just about perfect. I won’t say perfect because I don’t want them to take their foot off the gas! Review collected by and hosted on G2.com.

The only downside I have experienced with Telli is one they can’t do anything about for now. We operate in vastly different time zones, so when an issue arises there is a little extra wait. It’s never been a blocker, and moreover what they’ve added to the platform has mitigated many support issues. Review collected by and hosted on G2.com.

The support is great, the user interface is intuitive and simple. Review collected by and hosted on G2.com.

Every now and then, smaller bugs appear for which there is no direct answer. Review collected by and hosted on G2.com.

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. What’s especially impressive is how natural the conversations feel — people generally don’t realize or don’t care that they’re speaking with an AI. The onboarding was quick, and the whole system works well right out of the box. Review collected by and hosted on G2.com.

While the core functionality is strong, the platform’s interface could be more polished. It feels like the team is prioritizing the agent’s performance (which makes sense), but that leaves parts of the dashboard and reporting feeling a bit basic. That said, we’ve already seen improvements since we started, so it’s clearly moving in the right direction.

At the start, it took a bit of fine-tuning to have the agent pausing for the right amount of time during the conversation, in order to avoid talking over customers but also not having awkward pauses. Review collected by and hosted on G2.com.

They're continuously innovating and realising new products. They are very flexible and attentive. Easy to communicate with them. I'm very happy we are using Telli. Fairly stratightforward to integrate with our systems and we where live within 1-2 weeks. Review collected by and hosted on G2.com.

Billing gets a bit a complex, but they're realising a billing section soon. Review collected by and hosted on G2.com.

What I like about Telli is the team's hands-on approach with weekly feedback sessions and the very strong product! I have yet to see a product as strong as Telli's, especially on the German-speaking market. Review collected by and hosted on G2.com.

I would like to see even more insights and also have the opportunity to expand into even more countries, but the language models are not yet ready for that. Review collected by and hosted on G2.com.
