I have started watching the video on How to create an AI Voice agent for a Dental Clinic. The workflow is Cal.com -N8N - Retell then Twillo. My question is this. Is there a platform we can use that integrates everything under one roof. Also when meeting with clients what do you use to simplify the process of explaining things to them as a N8N workflow diagram would utterly confuse most people. Im based in Asia so I would have to deal with language limitations to explain things. Any ideas would help. Finally, is N8N reliable as I have watched a few video's where they say it breaks. Sorry I am new to all this and also old LOL.
