Getting these issues for our calls with VAPI numbers and with Twilio numbers. Can someone please help? Here are some call IDs with this issue: 019aa43a-19e4-7009-93f0-de7668813afc 019aa439-4d95-7115-8106-76b86ba91b02 019aa438-95b2-7223-9c69-3c473e8f4c12

For the last hour, none of my calls connect and I have "Call.in progress.error vapifault transport never connected" in the log. Dialing two different Vapi provided phone numbers that are tied to different assistants. Example call ID: 019aa40d-cbb5-7eed-b00f-dbd63e25e4b0

I want to notify slack on ANY error from the call. Right now it seems I'd have to specify each one. Is there a way to wildcard match or select all? filters: [ { type: "oneOf", key: "call.endedReason", oneOf: ["pipeline-error"], }, ], also, is the SDK or docs more up to date. there are different endedReason types in both

Hi, I am trying to us the VAPI warm transfer tool, if no one picks up I want it to return the control back to the VAPI Agent. It makes the call rings at the other end, the destination end eventually closes the call but the VAPI end keeps ringing and does not return the control back to the VAPI Agent. I am using the VAPI Call transfer tool. Does anyone have any reason why this might be?

I organized all my assistants into 3 folders. Today I logged on and they're all gone. All assistants are there unorganized. How did this happen?

I have made some corrections to my FreePBX configuration for Vapi, and both endpoint, AOR, and SIP registration are now working. However, I am still not able to hear the AI assistant during calls, and the AI assistant cannot hear me either. To help you better understand the issue, I have attached screenshots showing all relevant configuration files and settings. Could you please review my setup and advise on what might be causing the lack of audio in both directions? https://cdn.discordapp.com/attachments/1441148114332418260/1441148114789470370/Cattura.PNG?ex=6920bd45&is=691f6bc5&hm=109268f0ae0bd14b135fbb5c09c4ecc48ee4d51b0f2065316c3be0b0ee9cdc61& https://cdn.discordapp.com/attachments/1441148114332418260/1441148115368415242/Cattura2.PNG?ex=6920bd45&is=691f6bc5&hm=9ceb0b4bfddf9829c7d0b9360ff4daf099b468cf520df5a89e7213ccc1a5364e& https://cdn.discordapp.com/attachments/1441148114332418260/1441148115728994376/Cattura3.PNG?ex=6920bd46&is=691f6bc6&hm=ca2c56c1da3f6c3695269deae01de5c8bafbdd2ec549210cbbd3b8c15948bbd3& https://cdn.discordapp.com/attachments/1441148114332418260/1441148116157071420/Cattura4.PNG?ex=6920bd46&is=691f6bc6&hm=dd0326991b4c496ae7d95195e3bda27f9dc45f1c28ab2fa3e38883c97f6b706d& https://cdn.discordapp.com/attachments/1441148114332418260/1441148116488294572/Cattura5.PNG?ex=6920bd46&is=691f6bc6&hm=fa7d42f90232e362655d108273b11523d439e821b43a7cbe7f30c280f59c1868& https://cdn.discordapp.com/attachments/1441148114332418260/1441148116823703592/Cattura6.PNG?ex=6920bd46&is=691f6bc6&hm=ddefc04e97543f3e105c7e5b6ceacd6b24082ee8b6bfe38567c70248d56e65c2& https://cdn.discordapp.com/attachments/1441148114332418260/1441148117214036039/Cattura7.PNG?ex=6920bd46&is=691f6bc6&hm=1bbc4b2d0939d9c0a674a87e502751e86369bc3ec8d65b3f67a46c65b91d3123& https://cdn.discordapp.com/attachments/1441148114332418260/1441148117595590666/Cattura8.PNG?ex=6920bd46&is=691f6bc6&hm=2efb732d851202e6e2b888477f9e7e2a3410e9ae2d85387dbf203d272694216d& https://cdn.discordapp.com/attachments/1441148114332418260/1441148117935198389/Cattura9.PNG?ex=6920bd46&is=691f6bc6&hm=8bcd55176707f8e43617351b5a923a057db753aa2ce4059dc251e4532f26c6ae&

I’m working on a scheduling voice assistant for inspection bookings and ran into Issue: Assistant confirms a correct inspection date, but when presenting available slots, it speaks a different date. Detailed Description: User requests “Next Wednesday” → agent confirms Nov 26 → calendar check succeeds → agent announces slot availability for Nov 20 instead. The spoken output does not reuse the confirmed date, and instead it regenerates a new one. This is happening for almost any date involving twenty.. Expected vs Actual: Expected: After user confirms a date, all responses must repeat the exact same confirmed date. Actual: Assistant alternates between Nov 26 (confirmation) and Nov 20 (availability), causing user confusion and call abandonment. Call ID: 019aa27b-6518-7eec-9d9c-541f5dba4143 Time stamp: Assistant (2:17:04 PM(+00:32.84))

Hi VAPI team, I'm trying to integrate Twilio Verify API which requires

application/x-www-form-urlencoded

format for POST requests, but I'm having trouble with VAPI tools. WHAT I NEED TO SEND: POST https://verify.twilio.com/v2/Services/{ServiceSid}/Verifications Content-Type: application/x-www-form-urlencoded Body: To=+13417668501&Channel=sms WHAT I'VE TRIED: 1. API Request Tool: - Set Content-Type header to application/x-www-form-urlencoded - Configured body properties (To, Channel) - Result: Twilio returns error 20001 "Missing required parameters" - The body data isn't being sent 2. Found this Discord thread saying API Request tools are hardcoded to JSON: https://discord.com/channels/.../API-Request-Tool-adds-default-Content-Type Kyle mentioned "function tool will allow you to customize the header" 3. Function Tool: - Added Content-Type: application/x-www-form-urlencoded header - Configured parameters (To, Channel) - Result: "No result returned" error - Seems Function Tools expect to call my server, not external APIs? QUESTIONS: 1. Is it possible to send form-encoded POST requests directly to external APIs with VAPI tools? 2. If yes, what's the correct configuration? 3. If no, do I need to create a backend proxy that reformats the request? The API works perfectly in Postman with form-encoded data, just can't figure out how to make VAPI send that format. Any guidance would be greatly appreciated!

Hello, We’re experiencing an issue integrating the phone number provided by our local SIP trunk provider. The provider has checked their side and confirmed the following: - For incoming calls, VAPI is returning: SIP/2.0 401 Unauthorized. - For outgoing calls, the provider expects the From header to use the format sipaccount@sip.provider.com, but VAPI is sending phonenumber@sip.provider.com instead. As a result, VAPI receives the following error: call.in-progress.error-providerfault-outbound-sip-403-forbidden. Our org id: 0c72eb92-cfc0-4943-98d5-7d71788b5134 Could you please advise how we can resolve this and correctly configure the integration?

Hi guys, I need a way for data that is captured to be sent to make as it is recieved and not at the end of a call. Is it possible to do that? Thanks

Please help me out!!!

Hi @Vapi sorry for double report in the email and now here, I am not sure which one works better for you. We are getting an error: Phone number +493021923004 already in use by another org. When trying to import the Twilio phone. This is the phone we purchased and own. So we are sure that we didn't import it into other orgs. Can you check why we are getting this error?

I need an urgent information regarding the recent changes with Trieve. I understand there are a couple of workarounds provided by Vapi in the docs. However, we are thinking of self-hosting trieve and go from there. I am wondering if this will be still supported by Vapi if we keep this structure? If you can kindly provide me with a detailed response that'd be great. We have clients who are already upset with this sudden change and we want to land on something sustainable. Looking forward to hearing from you soon.

I’ve got an issue with {{customer.number}}. In almost all calls, the variable gets rendered into the system prompt normally (the full phone number shows up in the OpenAI payload). But in one specific call, the variable didn’t render at all. The system prompt was missing the phone number completely, which made the model hallucinate the last two digits (“52”). Nothing changed on my side between calls, so it looks like interpolation just failed for that run. Can someone check why {{customer.number}} didn’t get injected for that call? Here is the call id: 019a9846-0c1b-722d-b0e1-f120a57501fd

When importing a twilio phone number via VAPI api, is the provided auth token only needed for the initial import, or does it need to persist?

i can't seem to login, i've cleared my cookies and cache but whenever i like on dashboard it will just show the loading animation

Exactly as above. Is this possible?

Hi everyone! Do we also have text-based conversation handover to a human in Vapi?

Hi, We have a Squad handoff that is: Extracting all variables correctly Executing the handoff tool successfully Returning "Handoff initiated" BUT NOT switching control to the destination assistant Configuration Details: - Squad ID: 53fb76d0-ef3d-44a4-86cb-b96637565a34 - Session ID: 268e727d-26c1-4705-b0aa-3a9e27d0b075 - Alex (Source): e6edb9cb-2f41-45e7-88ef-a211e44393ca - Taylor (Destination): 4de11561-6f31-42b7-a145-0fff262dbdd2 Evidence from logs: - Handoff tool call shows all variables extracted (destination="4de11561-6f31-42b7-a145-0fff262dbdd2", contactId="691ca9ee14abe945a7bd6e35", etc.) - Tool returns "Handoff initiated" - Alex continues talking instead of Taylor taking over - Taylor has First Message configured - Everything follows your documentation exactly This appears to be a Squad routing bug

We have a very basic squad that handles inbound phone calls. We have a tool that hits our backend endpoint:

/api/user/{{customer.number}}

When using this in a workflow or just a single assistant, we get this: ✅

/api/user/+1234567890

<---- working perfectly When using the same assistant with the same tool in a squad, we get this: ⚠️

/api/user/{{customer.number}}

<---- LiquidJS tag does not get replaced The documentation around this is very confusing. Is there some difference in customer variables being passed around when using assistants in a squad?

I can see the option to turn on HIPPA Compliance for an agent but I want to confirm - does hippa compliance only apply for voice agents? what about a chat bot? If I for example embed a widget with chat capabilites on my website then is that hippa compliant?
