09/09/2025, 1:32 PMI try to update my phone number in Postman. I use:
curl -X PATCH https://api.vapi.ai/phone-number/id \
-H "Authorization: Bearer " \
-H "Content-Type: application/json" \
-d '{
"fallbackDestination": {
"type": "number",
"number": "+90850*****05",
"numberE164CheckEnabled": true
},
"numberE164CheckEnabled": true
}'
But i still get the error message and call ends after it. What should i do more?

09/16/2025, 6:21 AMI'm trying to update a phone number. I actually added my phone number to the front end, but it didn't work. I tried Postman, and I got these, but they still didn't work. Even though it looks like this on the image, when I call, it won't transfer me to the number in the Fallback Destination.,

09/20/2025, 5:02 AMIf the phone number you imported to Vapi is working, it should transfer the call to the fallback destination. Could you please confirm if your BYO phone number is working if you configure an assistant Id to it?

09/22/2025, 6:15 AMI can speak when I connect the AI assistant for incoming calls. However, even though there is a fallback destination, it gives me an error when I remove the AI assistant.

10/15/2025, 12:20 AMWe apologize for the delay in responses lately. We are in process of making some changes to our workflow in how we handle support requests. The good news is that we are starting to get back on track of having a 48 hour response time and we would like to start cleaning up anything old.
With that being said, just wanted to check in with you to see if you have made any progress or changes to your project since support has last reached out.
