Hello,I have successfully configured a BYO SIP Trunk to work with a Russian provider (Plusofon).

My setup: I have an Asterisk server in a Russian datacenter (IP: 85.198.108.143). This Asterisk successfully registers with my provider and can make outbound calls. I have created a Credential in Vapi (My-Asterisk-Gateway, ID: 69e8ecd3-f719-49f5-95d-a7f6-9a74e295145f) with my server's IP. I have created a Phone Number (My-Moscow-Number, +74952305170) and linked it to this credential....

Structured Outputs 404 Error, Vapi Support then removed Structured Outputs

https://discord.com/channels/1211482211119796234/1405654269549609030 I reached out last week because my structured outputs tab was returning with a 404 error. Then some vapi support agent named King said he fixed the issue when all he did was REMOVE structured outputs from my dashboard. When I told the agent that wasn't my problem he stopped replying. WHAT IS GOING ON WITH THIS VERY SIMPLE ISSUE?...

Query tool Issue

Been using the query tool for knowledge retrieval and most of the time or all the time, the responses are incorrect. I am using docx and PDF both in very structured format for retrieval.

Trouble transcribing

I created a good prompt and the AI agent seems to understand what it's supposed to do, however it cannot hear me well. I tried multiple transcribers and the best one is google gemini 2.0 flash multilingual, but even this it cannot understand most of what I say. I tried switching languages, switching microphones, same issue. ...

Transfer Call "Warm transfer -Experimental" not working

I set everything up correct, and every other transfer mode is working correct as described in the docs, but when i try the warm transfer -experimental, which i want to use, to have the function of a fallback, if nothing is reachable, i do not even get the call forwarded at all. Why is it not working? Any major problems with that currently? It just keeps ringing on one end, and the destination does not receive any call....

Can we create a workflow object and execute it directly in our code?

I’ve been experimenting with the Web SDK. Right now, I’m calling vapi.start with a workflowId that I created beforehand in the dashboard. However, I’d like to avoid creating a new workflow in the web app, I would like to manage this in the code. Is it possible to define a workflow object directly in my code and pass it to vapi.start (instead of passing a workflowId)? Or do workflows always need to be created via the API/dashboard first? I would like to define the workflow programmatically and then execute it to manage for example the user prefered language, etc.......
