Excellent information!!! I love his voice — it's very soothing and calming. He is extremely patient, gets straight to the point, and doesn’t talk excessively like many other teachers. He explains concepts clearly and efficiently, which makes learning so much more enjoyable and effective. Highly recommend!
By Aslam Miah on 9/29/2025
I honestly couldn’t have asked for a better course on AI voice agents! I’d been searching for something that really focused on Retell AI, and I’m so glad I found Manthan’s course. He explains everything so clearly, and it’s honestly been a complete game-changer. On top of that, Manthan helped resolve a hiccup I had with a Make.com scenario not working, which shows the level of support he provides. The only small feedback I have is that the n8n lessons felt a little rushed—but aside from that, I couldn’t have asked for a better course. Huge thanks to Manthan for putting this together — absolute legend!

Though some features work differently in the EU, it isn't difficult to find out what settings apply here. I'd be glad if the presenter give some hints about the other settings that we don't bother. I only learn what settings to set or keep. I'd expect some explanations what are the other settings ir Retell or other wbb applications even if I shoudn't temper with them.
