Hi, I wanted to use the Azure Realtime model instead of OpenAI directly, as we have credits available with Azure. However, I don’t see an option to select the Realtime model after choosing Azure as the provider. Do you have an estimate on when this option will be available? Thanks,

I wanted to build a start button and after clicking on that I wanted to talk to vapi. I have public, private, assistance, workflow ids. But I am not being able to connect at all. here's the code i used. import React from "react"; import Vapi from "@Vapi-ai/web"; const FRONTEND_KEY = import.meta.env.VITE_VAPI_FRONTEND; const ASSISTANT_ID = import.meta.env.VITE_VAPI_ASSISTANT; export default function App() { let vapi = null; // hold the instance const startCall = async () => { vapi = new Vapi(FRONTEND_KEY); // create instance await vapi.start(ASSISTANT_ID); // start call console.log("Call started"); }; const stopCall = async () => { if (vapi) { await vapi.stop(); // stop call console.log("Call stopped"); } }; return ( <> Vapi 2.x Call Test Start Stop ); } But i keep getting error 'Vapi is not a contructor' https://cdn.discordapp.com/attachments/1444610545738055750/1444610546057084938/Screenshot_2025-11-30_102320.png?ex=692d55e9&is=692c0469&hm=5206f7f46fdda695029c5a540a9307e8b6198842184b7ed0c7c89075767e626d&

Hello Vapi team, I have a problem with the telephony configuration of my assistant. I already linked a Twilio phone number in the “Phone Numbers” section, and calls to this number do reach my assistant correctly. However, inside the assistant settings, the Audio Source is always forced to “Web”, when i switch to Twilio, i don't have the option to publish my changes, and when I refresh my browser, the "web" mode returns. In addition to this, in Settings → Integrations, the Twilio integration does not appear at all, so I have no way to select or enable Twilio for the audio pipeline. Everything suggests that Twilio is not enabled for my organization, even though I am already using a Twilio number. I would like "twilio" mode to be activated for me. The email of my account : aminezz2@outlook.fr Could you please enable Twilio for my organization so I can use the Twilio audio mode instead of the forced Web mode? Thank you very much! https://cdn.discordapp.com/attachments/1444482581579174040/1444482582107389993/IMG_0920.jpg?ex=692cdebc&is=692b8d3c&hm=afd75073c09aad54955ae757418f0de665252ffd072444fe84d1a8de895e4d5f& https://cdn.discordapp.com/attachments/1444482581579174040/1444482582518693958/IMG_0919.jpg?ex=692cdebc&is=692b8d3c&hm=d9eb73b29f3aa09278a49df012128ddd62f1cdf68ce94b204054db84a6caab61&

Hey there is an issue with my GHL integration... Trust me it's not some stupid issue that can be solved with docs, or an SOP. There is a tech error on the backend of some sort, can you help me out please?When I try and intehrate and grant VAPI permission to all scopes it does not sub,it. this is happening days

I have just experienced this critical issue... call recordings were all available on my account, now I came to check some recent logs after a few calls came in and not only are the new calls not there, but all previously available call logs and recordings all disappeared all the way back to Nov 21st... I've noticed this issue has been brought up by several other users... this is critical to the user experience and not to mention to maintaining a positive experience and clear records for our end clients that we are serving via VAPI. Can someone please tend to this and check my account/this VAPI Platform wide issue? This is not a sustainable approach if I am to onboard even more clients... please advise #1211483291191083018

When I am dialling a number and the recipient has not picked up the phone, when I try to send the end-call signal to Vapi's controlUrl, it just processes for a while and eventually I get a timeout, the call does not get ended either. Example call - https://dashboard.vapi.ai/calls/019acf1b-8f39-7cc1-a5a8-58c4e5a3b190 FYI I am using a Twilio integration. Maybe there is another way to end calls?

Hi Team, I've recently started using Vapi for outbound calls, I also purchased a phone number from Twillio and I configured it in the Vapi dashboard but When I upload a campaign.csv for calls it not calling anyone, its just showing in progress and queued but no one receives any calls. I tried adding my own phone number and my friends and family's phone number but for some reason its only calling me and not calling anyone else. Why is this happening, can anyone explain please.

Yesterday everything was working perfectly when we were connecting the gohighlevel MCP (in "integrations"), but now it doesn't work at all (cannot even connect gohighlevel MCP anymore, it never displays as "connected" after several attempts on different vapi and gohighlevel accounts...). Vapi team, please advise, we need this integration to work 🙌

I changed nothing, it worked since end of Sept. 2025. Now all of a sudden, the assistant halt after sending the SMS (successfully) and waits for user utterance. If no utterance call hangs up due to idling. CALLIDs: 019acb6c-7cde-744a-a478-3307a11f77a9 019acb68-0c1f-7bb7-b186-ee62be0148e8 019acb61-8779-711f-a335-e249a3485b22

Hello, I’m trying to connect my ippi phone number to Vapi using my SIP credentials, but I’m facing an issue when placing calls through Vapi. When I configure my SIP account in Vapi, I am forced to use the server’s IP address instead of the domain sip.ippi.com. Because of this, the SIP messages sent by Vapi use the IP instead of the proper domain, which causes my calls to be rejected with a 403 error. For reference, calling with Zoiper using the same SIP credentials works correctly. Here is the problem as identified by ippi support: The FROM header sent by Vapi is incorrect: From: ; It should be: sip:MY_USERNAME@sip.ippi.com The INVITE request is also incorrect: Vapi sends: INVITE sip:33671514802@194.169.214.30 It should be: INVITE sip:33671514802@sip.ippi.com Because the SIP URI uses the IP instead of sip.ippi.com, ippi’s platform rejects the call. Could you please adjust the SIP configuration so that Vapi uses the domain sip.ippi.com in the FROM header and INVITE URI instead of the IP address? Thank you for your help!

I would like to be able to make more than 10 simultaneous calls. Is it possible to increase this number?

Hello, I am adding my number from the PBX and entering the required details. My PBX service provider asked me to contact you and inform you that: “We want to receive the calls via peer-to-peer from the IP address 185.86.153.52. The PBX sends the DID as 903845353963.” They said this needs to be checked on your side. Could you please take a look? Thank you.

For two days now, I am trying to integrate Twilio phone number in order to run outbound calls with my Agent. I alredy did test calls with Vapi Free numbers and got really good results and now I want to scale. PLEASE, I need guidance.

ASSISTANT requires user utterance to progress to next task in prompt, after triggering and succesfully execution of the SMS Tool call and/or BookAppt Tool. Call ID: 019ac9dd-d4d8-7dd7-86df-2d35930fed23, 019acb4b-1e82-755d-bcf5-d10e631d8842 . Same with booking tool call. Assistants and tools were unchanged since sept 2025! The error popped up around after 21st of November, all calls before that date worked perfect. The assistant setup was working 100%, totally fine, but all of a sudden now requires the user to give an utterance after successful tool execution! Makes no sense and my clients are upset. It is not limited to specific assistant. Important: I did not change anything on agent side or tool side for app 2,5 months. These are in production, tested and 100% stabel assistants and tool calls. All worked fine until a few days ago, somewhere after 21st of Nov. I assume VAP changed something in the backend! The assistant executes the tools successfully but then awaits some user utterance to progress to next prompt action. The tools do not require any user interaction after execution.

Hi @Vapi , I'm trying to add credits to a new organization I've created, and I keep getting the following error pop up (screenshotted).

Call ID: 019ab6e2-6a26-7ee4-ac7c-f273b25e750b There is an issue in this call where I noticed the AI agent would call the same tool twice at the same time, resulting in an error.

You'll need to share more details on your Make scenario, ideally with screenshots. Probably best to share that in the official [Make Community](https://community.make.com/) rather than here, as there's 100's of Make experts there willing to help!

Hi everyone, I’m having an issue with outbound calls and hoping someone can help or share insights. On 25–26 Nov 2025, almost all calls made through Vapi using our Telnyx SIP numbers were answered by a “bot”, but the recipients didn’t actually receive any calls. I tested with my own number — I didn’t get anything, but Vapi logs show the call was “bot-answered” for about 6 minutes, and it charged around $0.40. What’s strange is: Everything worked normally before that It only happens with Telnyx SIP numbers Our Twilio number works fine Has anyone experienced something like this? Could this be a Telnyx routing issue or something on the Vapi side?

I have an old phone number from Telnyx and for some reason the caller ID for my new number keeps using the old one. I recreated the SIP trunk connection twice now What causes the issue, why is my caller ID still the old number?
