Hi, I need a tutorial to create how can I connect web call and retellAI Agent.

Good morning y'all, Alice from Abba HVAC in Austin. I need help We've built an agent with RetellAI, then connect our business number to Twilio. We also need to have Talkyto app so we can text and call with our business number. Somehow, somewhere, I've completely broken the connection and now the calls to our business number cannot even be verified. Please help

Good morning, I have a customer asking my Agent to pause for 1 minute. but the Agent is not capable of that. Is it a limitation by Retell Dashboard?

Hi does it possible to get text and voice conversation via api ? I want resell agent like an a Saas throught my site ?

Technical Request for Browser-Based Voice Integration with Retell Hello Retell Support, We are implementing a real-time, browser-based voice interface for our internal legal support agent (“Andrew”), which is already fully configured as a Retell phone agent. We’ve deployed a front-end environment on Vercel and now need to connect the browser’s microphone stream directly to Retell’s real-time agent engine. We need clarification on the official Retell-supported method to establish a web voice session (WebRTC/WebSocket/SDK) without involving PSTN or SIP calling. Enable real-time streaming audio from the user’s browser microphone to our Retell agent, receiving streamed TTS audio responses, with low latency suitable for conversational use. Please advise on the correct Retell integration path for this browser-native voice agent.

I am having trouble getting the post call analysis, sending it through the webhook, and updating or creating the customer's contact info. Any help would be appreciated.

If the agent is transferring a call to an employee, but the employee doesnt answer, how do we take the call back and transfer to someone else? Also, how do we release the call to the employees voicemail instead. Exploring two options for customers. Currently the AI Agent has been taking back the call and trying it to the same person again.

We are having trouble setting up Retell’s AI agent into our company’s RingCentral so the calls are forwarded to the AI agent at certain times (off hours). Simple call forwarding does not work for some reason, there is around 20 seconds lag most of the time before you can hear the agent, and the agent starts talking from the beginning while you are hearing the ringing sound for 20 seconds. P.S. the agent is ready, we just need properly working call forwarding and the agent to see the clients numbers. Please make a guide on this !!! RingCentral is 20% of US business VoIP Market, and you don't have a dedicated tutorial. Its crucial guys !!! BTW, mb we are doing smth wrong with the call forwarding, we are trying out the SIP Trunk thing, and there is literally no info on how to do this !!!

Hello Team, I need urgent assistance with the Native SMS feature (send_sms). I am encountering a blocking error where the system claims I am not on a phone call, despite the logs confirming otherwise. The Issue: My agent triggers the native SMS tool correctly, but the execution fails immediately with the error: Encountered error in sending SMS: SMS is only supported for phone calls Technical Context: Call Type: Real Inbound Phone Call (Physical Mobile Device calling the Purchased Retell Number). Log Evidence: The call logs clearly state the type is phone_call (NOT web_call), yet the tool rejects the SMS request. Setup: I am using the standard Native Function with "Static Sentence" content. Number Status: The phone number is active and purchased within Retell. My Questions: Bug Confirmation: Why does the system throw a "web call" error on a proven inbound phone call? Is there a backend restriction on my account or number? Best Practices: To rule out any configuration errors, could you confirm the ideal JSON definition for the parameters section when using "Static Sentence"? Prompting: Is there a specific instruction required in the System Prompt to ensure the LLM handles the tool execution status correctly? I have attached a screenshot of the log showing the contradiction (Call Type: Phone Call vs Error: Supported only for phone calls). Could you please investigate?

Hi all, Im struggling to make connection when calling the number I have purchased through Retell, and also, how do you go about allocating a UK phone number and existing uk numbers? many thanks

It’d be nice to get a demo on usage for n8n community node. There is no documentation so far.

Hi all, I'm not sure if there are existing steps by steps created out there or any similar post. Please direct me to that post if there is. I'm not a developer but an user. My company do have an external SIP trunk vendor providing their SIP trunk services to us with a dialer on laptop. I have the server URL, username and password. I tried set it up in the Retell.ai however it doesn't work. I also ask my vendor to whitelist the IP: 18.98.16.120/30 (All regions) My SIP trunk vendor ask for the logs but I'm not sure where can i found it. The end reason is dial no answer when i call with "+" + 60 (country code) + mobile number Or telephony provider unavailable when i call without the "+" 60 (country code) + mobile number When i call in the vendor's dialer, i only type 60 (country code) + mobile number. It will be able to connect to my phone. Would like to seek your assistance or input what should I do next?

Can I directly use the retell js sdk for the mobile app?

Hello, I am trying to allow users to be able to change information previously extracted in the conversation at any given time/node. I am not sure how to achieve this. What I tried was making the extract variable nodes into global nodes, but that does not seem to work because I am unsure how to jump back to the previous node, the one where the global node was triggered. For example, If I have the flow of nodes like: A -> B -> C -> D and I extracted the name of the user in node A with its respective extract variable node, I can be in node D and say "Oh, I forgot to give my last name" it jumps back to correct the name variable and then go back to node D and keep the conversation going naturally. How can I achieve this behavior?

We use a Retell AI voice agent workflow (question nodes, extract variable nodes, function nodes) in a Next.js app with RetellWebClient for web calls. Currently, users can only respond via voice. We want to allow users to type text answers in the same conversation while keeping the same voice agent workflow. Questions: How do we send a text message to an active web call? What API method/endpoint should we use? How do we get the callId or conversationId from an active RetellWebClient web call? Can a voice agent workflow accept text input mid-conversation, and will the extract variable nodes and question flow continue normally? Please provide API documentation or code examples. Thank you.

I run a digital marketing agency where run facebook ads for my clients. i intend to run ads where the leads fill out facebook instant forms. i want a work flow in n8n where when an instant form facebook lead comes in, i have my retell ai bot send an sms to that lead to book an appointment and if no answer then calls at 10 minutes to book then appointment, uses google calendar to check for availability and book the appointment with cal.com and then pushes that lead through my clients jobtread crm. looking to see if anyone can please point me in the right direction for the best work flow set up on n8n for this run with minimal hassle getting setup and operating. I'm really trying to crush it for my 2nd client and need this work flow to absolutely shine for my client and im completely green to n8n 😂 thank you in advance

Inbound SMS toggle not appearing on my Telnyx number. Inbound calls work fine. Agent assigned. How to enable SMS replies? Thanks.”

Worse than getting rejected: 1. It takes a week to get rejected 2. Getting rejected twice for the same reason 3. The lack of specificity in the reason why both times What is best practice for writing SMS opt in language? Is there a template? https://cdn.discordapp.com/attachments/1478141840552230912/1478141840812413132/image.png?ex=69a7525d&is=69a600dd&hm=741dc79f2d816ae454379361fdbeaa6ebd3e1909c8a0e15cee5bd7f23cabf9e9&

I'm curious what others have done in the early stages of building a voice AI agency. In many cases I spend a lot of time determining the right build flow. Not necessarily single vs multi prompt, but more about the architecture. In all of my agents that I've built, its taken serious amounts of time and I ask myself if there are easier ways to quickly determine the correct flow based on specific criteria. How have you all dealt with this? Are there tools that helped Is it just grinding to learn as much as you can or is there a simpler way, maybe even retell guidance that I've overlooked? I know there are prompt generators when creating the agent but doesnt always translate.

Hi everyone, I'm hoping someone can help me. I've been stuck on this for almost 6 hours and feel like I'm missing one small setting somewhere. I'm using an Inbound Call Webhook with Retell and Make.com. My flow is: Retell → Make Webhook → OpenAI → Google Sheets Search Row → Webhook Response → Retell The goal is to retrieve the caller's information from Google Sheets and use it inside the Retell prompt. Everything appears to be working correctly: ✅ Inbound webhook is triggered ✅ Phone number is formatted correctly and matches the Google Sheet record ✅ Google Sheets finds the correct row ✅ Webhook Response returns the caller information ✅ Retell Call History → Detail Logs shows the webhook response with all the correct data Example response:

json
{
  "first_name": "Mark",
  "phone_number": "+61473503315",
  "email_address": "mark@email.com",
  "dental_service": "Teeth Cleaning"
}

I've already tried: * Confirming the correct Inbound Call Agent is attached to the number * Saving and republishing the agent * Matching variable names exactly (

first_name

) * Using variables in both the Welcome Message and Agent Prompt * Testing different webhook response structures * Hardcoding test values * Multiple test calls after each change The issue is that when I use:

text
{{first_name}}

Retell literally says:

text
{{first_name}}

instead of:

text
Mark

What confuses me is that the Detail Logs clearly show Retell receiving the webhook response successfully. My question is: If Retell is receiving the inbound webhook response, how do I correctly access those values inside the prompt? Is there an additional mapping step or a different variable syntax that I'm missing? Any help would be greatly appreciated. Thank you!

Im having trouble doing an SIP trunk from a ring central number into Retell. Ive tried to do it but the credentials dont match on either end. Curious if a way exists or how we could integrate a number from our ring central domain into retell
