Hi, Outbound calls via api https://api.vapi.ai/call are queuing and work ok when calling Australian numbers, but no call is ever received when trying New Zealand numbers. Vapi API logs show OK with queued, but in the call logs you can see errror: "An error occurred in this call: call.start.error-get-transport" Twilio logs don't show any fails or errors either for the calls that don't work.

Is this functionality even working ? with clean assistant and added files to model it never uses them. Adding prompts to reference knowledge base always results in : Cannot read properties of undefined (reading 'message')

This started today. Or I noticed it today anyway but the authentication is not working. I goes through its cycle but won't authenticate. I tried in Incognito browser as well. A few days ago it worked fin with the same agency different sub account but now nothings working . Thanks!

I havea sip proxy/server, it's possible to connecte vapi on my VOIP server ? i dont understand how it's work thanks for your help

I am serioulsy frustrated with this platform and the bugs with it... I am trying to call an api tool that has path parameter Example [GET] https://api.test.com/{{someVar}}/resource now, this variable is passed in to the squad and squad is using an agent that uses this tool.... the damn path parameter is just not getting filled... I tested this with Agent, it works... i test it with Workflow it works... but it doesnt work with squad... Worklist is not recommend to use by Vapi... and Agent is bloated... that the hell do i do here?

Vapi is lagging on the call, agent cuts out. Is there something we need to do on our end?

Hello, as we all know, GPT 5 has been pretty bad for vapi, but how are the two new 5.1 models? Are they any good? I'm also curious to know if the latency times are correct, 5.1 instant is just as fast as plain 5.1. It also has the exact same specs. Any noticable difference there?

I've previously been using 'experimental' warm transfer but it doesnt work 100% of the time. So I'm trying the TWIML method. I have it working speaking a message "this is a call from company, the customer is called..." and at this point I want it to say the customer name. I've used {{customer.name}} but it reads out "customer name". Is this possible and if so how? The same with call transcript/summary. On the other call transfer methods the options to create the summary plan are there, but it doesn't show on the TWIML configuration.

I'm trying to figure out why, for the transcript, the LLM output is sent to the speech-to-text. Why not just directly send me the LLM output? Is this a setting I can configure? We're building out a third-party web widget that's pulling in the transcript, and it's taking it from the speech-to-text. It would be better to just give us the exact LLM output, and I can't figure out how to just get that exactly, the actual LLM output. So I could put that into my transcript for the user.

I am using the VAPI Dashboard on MACBOOK in Browser CHATGPT ATLAS and it is lagging like crazy.

Everybody's seen all of the post. With this error I've tried everything that you've mentioned. Created the new API keys, cleared the cache, did a hard reset. Still nothing. I see multiple people with this error and it's gone unresolved. Can anybody help here?

Is it possible to update the assistant system prompt during a call? Do dynamic variables get updated every turn of the conversation? Thanks!

Hello! I'm following the Live Call Control docs at https://docs.vapi.ai/calls/call-features , but I don't see any monitor object being returned after I create the call. Am I missing something? Or perhaps I'm not on the right Vapi tier?

Details: I am creating a recruitment bot using Gemini-Flash 2.5 and VAPI. During the conversation, it keeps breaking with the error shown in the attachment. It has been two days and I still haven’t been able to resolve it. With Gemini-Flash 2.0, it works well.

Hey everyone, I have connected a Twilio number in Vapi and am receiving incoming calls, but the call log still shows the inbound call with Assistant = “No Assistant Assigned” even though the assistant is set in the phone number settings. Info: Org: Twilio number: +41 43 505 10 54 Assistant name: Demo Inbound settings in the dashboard: Inbound phone number = +41435051054, Assistant = Demo Twilio: “A call comes in” → Webhook https://api.vapi.ai/twilio/inbound_call (HTTP status 201 in the Twilio call log) In Vapi calls, I see my call as Type = Inbound, but the ASSISTANT column says “No Assistant Assigned.” When I test the same assistant directly via “Web Call” in the dashboard, everything works (call log then correctly shows Assistant = Demo). Can you please check whether there are multiple PhoneNumber objects for my Twilio number, or why the inbound handler does not link the number to the assistant even though it is set in the inbound settings? Relevant call IDs from your log: 019a87ae-ea68-7773-aa33-fc1adeafe44b Thank you & best regards, Silvio https://cdn.discordapp.com/attachments/1442893938225713234/1442893938565578772/4a986c99-908c-44d4-97f8-51673d6c4493.png?ex=69271732&is=6925c5b2&hm=60e978bdb50d9ddffafde2e12f4f651ddb546e369f8da8bf6db4eefb97d50142&

We're using elevenlabs as primary voice provider, but when we change the synthesis settings, is not reflecting. We figure out that this is a caching. Which is not a problem at all. On other hands, we would like to know 1. What is the TTL for cached voices? 2. Is there any way to enfore caching expiration? PS: We don't want to disable the caching at all

I'm trying to integrate vapi to my cal.com calendar to book appointments with clients automatically, but vapi is booking at unavailable times and the info is not being transferred to the calendar. can you help?

I already created a post with this https://discord.com/channels/1211482211119796234/1435697639743033436 but it seems after a while posts don't get any other answer so I am reposting to maybe have it fresh and get some eyes on this. I already tried the configuration suggested and it does not work. It does not even allow to set that configuration.

I have a Vapi assistant in my dashboard, and I want to connect it to three different bot interfaces: mobile, web app, and phone calls. For each connection, I also want to pass the customer’s details and name using the assistant override feature. Can this be done, and if so, how? Additionally, I want to enable call-forwarding only for users who contact the assistant via phone calls, and not for those connecting through mobile or web applications. How can I configure this behavior?

I'm using a SIP trunk. Outbound worked, but inbound didn't. So, the system isn't picking up incoming calls. How can I fix this?

Hi everyone, how can I send a demo link for people to test my squad of assistants? Normally, for individual assistants, I can do this, but for squads, I can only share a phone number right now. https://cdn.discordapp.com/attachments/1442812696855711754/1442812697178804235/image.png?ex=6926cb89&is=69257a09&hm=f13279bee3b494b572e309553a28ce27eb7dfd9fc18fa207a37975752b660f98&

I'd request your urgent help to this matter, our systems are scaling fast (and in Production) and Vapi APIs are responding in a very unreliable manner. Hi Team, We have a system with following properties 1. We have got 5 numbers where each number handles one call at a time. (We have limitation of one active call at a time from number provider) 2. A number is marked busy when a call request is sent to Vapi 3. A number is freed up and ready to accept calls again when we receive status ended from Vapi Webhook We still receive concurrency limits errors a lot of time. (even though we should never considering Vapi default concurrency limit is 10) For an instance, On 24 Nov 2025, at 4:43 PM - 4:44 PM (IST), there are 10 calls which are showing in Vapi call logs which were all customer busy or customer did not answer Still, all the calls between 4:44 PM - 4:48 PM failed with concurrency limits hit error. (there are no call logs between this duration in Vapi signifying that system was free during this time) It seems that Vapi doesn't free up concurrency sometimes even when there are no active calls going on. Thanks, Karun

Hello, I'm interested in connecting a voice agent for up to 250 lines. Who can I speak with?

We are currently evaluating Vapi as the orchestration layer for a healthcare voice agent application. We understand there is a $1,000/month add-on for HIPAA compliance and Zero Data Retention (ZDR) on the Vapi platform. Before we commit, we need definitive clarification on how this add-on interacts with downstream model providers, specifically regarding Business Associate Agreements (BAA). We have been unable to definitively clarify from the help docs here: https://docs.vapi.ai/security-and-privacy/hipaa Could you please clarify the liability in the following two scenarios? *Scenario A: Vapi Managed Keys * If we pay the $1,000/mo HIPAA fee and use Vapi's default/managed keys for Deepgram (STT), Anthropic (LLM), and Cartesia (TTS): - Does Vapi's BAA with us cover these downstream providers as your sub-processors, and are the sub-processors required to adhere to ZDR? - Or are we still required to hold our own separate enterprise contracts/BAAs with Deepgram/Anthropic/Cartesia to ensure they do not retain PHI or violate ZDR? Scenario B: Bring Your Own Key (BYOK) If we bring our own API keys for these providers to get direct pricing: - Does the "HIPAA Enabled" toggle in the Vapi dashboard technically prevent these downstream providers from logging data on their end? - Or is the ZDR status strictly dependent on the settings/contract associated with our specific API keys? We are trying to determine if the $1,000 fee provides a "compliance wrapper" for the entire stack, or if it only covers Vapi's orchestration logs.

Hello, I’ve been trying to get in contact with someone from Enterprise Sales. I need to discuss signing a DPA. Could someone please reach out to me?

Hi there, we have been using a twilio telephony number with transfers and noticed our twilio is paying for the call after the transfer. We are switching over to a SIP trunk connected number on twilio and will add transfer blind transfer with verb REFER, but i am curious whether if we transfer to a sip system (but through a phone number) will their system take over the call?

It's all set up and with a system prompt that takes into consideration the proper numeric pronunciation and style to present the information in the Spanish language. Strict direction to speak out in Spanish I see the 11Labs and Azure and others 'supposed best voice interfaces' to fail and mixing up the numbers and some wordings with a strange intermittent language and sometimes english and french. $20.57 is 'veinte (correct)' with fifty seven (incorrect) cents. I tried the most powerful models such as Llama 3.1 & 3.3, came back to GPT 4.1 but nothing... I'd like to line up a troubleshooting ticket with 11Labs in parallel but I don't want to raise a ticket with 10 service providers, it all should be converging here. BTW, using Nova 3 and it works fine (spanish driven)
