Getting an error when trying to upload a CSV file to trigger outbound calls via VAPI. The headings in the files have tried "phone_number" and "first_name" as well as "number" and "name". The phone numbers are all in +61 format as well. It's a simple file with 11 numbers and only two columns, as wanting to test this before we go ahead and upload the full database. https://cdn.discordapp.com/attachments/1364551825365405786/1364551825587572776/Screenshot_2025-04-23_at_8.22.09_pm.png?ex=680a156b&is=6808c3eb&hm=c42eb4c90a67b23900fd3721459ca51559b41601b35ac683ab9896caf7679e7b&

According to the information I found, VAPI expects phone numbers in E.164 format with the column header likely needing to be

customer.number

. Try reformatting your CSV to use this exact header and ensure your Australian numbers are properly formatted (e.g., +61XXXXXXXX). Additionally, be aware that VAPI might have limitations with non-US numbers, as some sources indicate it may only support US and Canada numbers. If this doesn't resolve the issue, I recommend contacting VAPI support directly for specific guidance.

Use a UTF-8 encoded CSV with headers phone number and first_name, ensure numbers are in E.164 format, remove empty rows or special characters, and reupload.
