We have configured voice assistants and the dashboard seems to have a bug which makes the assistant configuration page not load.

Hi, I am connecting to my assistant through WebSocket. When I request for the WebSocket URL from VAPI servers, I send under assistantOverrides the clientMessages, with "tool-calls-results" and other control messages I need to receive. For some reason, I receive all the control messages I need - but not "tool-calls-results". Under "Call Logs" in the website it can be clearly seen that the assistant receives the response from my API accurately, and he also provides speech-answer for that. I already tried it tens of times to figure out if the problem is in my code. One call id example: 019ad950-5927-7cc8-9769-6fdf6a0533e1 Note: I also tried to wait for longer time before I hang up the call. Still - never received this specific control message. It's important for me to receive it, as I need to show the results as a component in the UI. Thanks!

Hi, I am making a voice AI agent that sends the transcript of the entire completed call to AWS S3 Bucket using a Server URL. The workflow is VAPI calls the user -> VAPI sends the transcript to AWS Lambda function via Server URL -> The function saves the transcript to S3 Bucket. In the Server Messages section, I see there are 2 options. One is "Transcript (Final)" and the other is "transcript". Can someone please help me understand the difference between the two and how to use them? You can find the Server Messages section if you go into an already created VAPI Assistant, then click on "Advanced", click on "Messaging", and click on "Server Messages". I really appreciate your time and energy. https://cdn.discordapp.com/attachments/1444991681857323068/1444991682104918016/image.png?ex=692eb8df&is=692d675f&hm=b6d2d3951cc429f1fdd77a5a8df125960004b8420f0474c255fec2e55939d33c&

Hi, I’m setting up a Squad in VAPI and running into a few questions. I want a dispatcher to work with multiple sub-agents, but I want the whole squad to sound like one single agent to the end user — so no “let me transfer you to…” or any obvious handoffs. I’d love to hear your best practices on: - Keeping all sub-agents aligned in voice/personality, so everything feels seamless. - Setting up good collaboration between dispatcher and sub-agents: When should the dispatcher answer something directly, and when should it delegate? - Making sure a sub-agent can hand results back to the dispatcher without it being noticeable to the user. - Useful settings or configurations (e.g., “agent/user speaks first,” role setup, prompt structure, etc.). Any example prompts or templates you use to make a squad behave like one unified agent. Any tips, examples, or “gotchas” are more than welcome! Thanks! 🙌

Hi, Can you please help me with two things 1) Add "answeronbridge"=true for my API when dialing Twilio ------------- Communication received from twilio Team For your reference ///// Here is the corrected TwiML: (This is a reference and values might need to be replaced. ///// _____________________ 2) disable the Twilio AMD, i am now using Vapi- having both causes huge latency like 6 seconds. -------------------------- Communication received from twilio Team For your reference //// If you wish to disable AMD, please remove all of the following parameters from your API request, Please contact to your application account developer.

An assistant I have been using for a while now just randomly disappeared, it still shows on dashboard but gives me this error "Error: RangeError Message: invalid_argument Timestamp: 2025-12-01T00:44:23.602Z" I have to make a copy one (thankfully have backup settings), but this is very frustrating, how do I get the original assistant back? @Vapi Support Bot

I've been trying ot add a query tool with a database to my vapi assistant but it always fails and this message pops up, I've tried diferent document formats, making a completely new assistant with only that tool, nothing seems to work, if someone knows a solution or knows how to fix this I'd love to hear from you. https://cdn.discordapp.com/attachments/1444804545031962788/1444804545241682070/image.png?ex=692e0a96&is=692cb916&hm=e84e535a5abd760f309cb63980fd357e7493573f2ca3829e27ab3652aed11391&

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.

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?
