What Retellai customers say
They position Retell as an easy way to build humanlike voice agents for inbound and outbound business calls. Their strongest evidence is operational breadth, with integrations, call flows, post-call analysis, low latency, and no-code setup appearing across the ads and reviews. You can attack the gaps around support transparency, country coverage, scaling cost, and advanced workflow complexity with specific proof and clearer limits.

Across the 50 supplied review rows, praise concentrates on easy agent building, natural voice, integrations, and production reliability. The meaningful complaints concern support availability, country restrictions, advanced-workflow complexity, usage costs, and localization. One row was set aside because it reviews Retail AI rather than Retell AI.

I have an issue with retell Ai batch calling…
I have an issue with retell Ai batch calling not making outbound calls but no one here to help. I have very bad exprience with this AI. no Support no one here to help after making paytimg.testing work fine. but when we pay nothing work. Totally a scam
This software is so good i have been creating an agent.
This software is so good i have been using it for my latest project and couldn't recommend them any more. So easy to use and the product comes out so good i am so pleased with it and cannot wait to continue using them.
Love the product
Been using the product for over a year, really love it! Lots of new features coming and also issues are fixed really fast!
Lackluster experience overall
The customer support was rather slow… the latency of the model didnt support fast paced conversations.
Highly advanced AI calling software for retail, though with slight latency.
I have been using Retail AI for our business, and overall, the platform provides a very good service. It is a highly advanced piece of software specifically designed for handling retail calls, and it truly shows in its capabilities. The system is incredibly sophisticated and robust. One of the standout features is how excellently everything is measured and tracked. The analytics and data provided give us deep insights into our call operations, allowing us to optimize our retail processes effectively. It feels like a truly next-generation tool for automating and managing voice interactions with customers. However, to provide a completely honest review, there is one technical area that needs improvement: the latency is a bit high during conversations. Specifically, when using the Gemini 3 Flash model, we have noticed that the response time can sometimes delay between 1.5 and 2.5 seconds. In a live call environment, this slight pause can occasionally disrupt the natural flow of the conversation. Despite this latency issue, the core technology is incredibly powerful. If they can optimize the response times, it would be absolutely perfect. Even as it stands, Retail AI is a fantastic, highly advanced solution that I strongly recommend for any retail business looking to upgrade their call systems.
Retell AI — Country restrictions with zero transparency or support
I've been trying to make outbound calls to Turkey (+90) for days and every single call fails immediately with the following error: "SIP status code 403 — telephony_provider_permission_denied: Dialed number (associated countries: TUR) is not included in whitelisted countries USA, CAN D13" The D13 error indicates a country-level block that cannot be changed from the dashboard. There is no documentation warning you about this before you spend time and money setting up your entire telephony stack. I purchased a dedicated external Telnyx number specifically to call Turkish numbers, configured everything correctly on both ends, and still hit this invisible wall. No clear support channel, no timeline for resolution, no transparency about which countries are restricted and why. Just a cryptic error and silence. What a waste of time and effort. Pathetic
Great experience with retell AI
