PHONE_NUMBER_REQUIRED

HTTP status	Retryable
`400`	No

What happened

Blujay needs to know which of your phone numbers to use: for a group operation, one of your numbers in the group; for a capability check, the number to check from when your workspace has several.

How to fix it

Include from_phone_number_id. List your numbers with GET /v1/phone-numbers.
