How can i authorize phone numbers to be able to send SMS via the API.
Calling /restapi/v1.0/account/~/extension/~/sms only allows me to send from one number (the main account #).
after review of the API and FAQ page i noticed another API call to Get a list of Phone numbers Authorized to send SMS account/~/extension/~/phone-number. From the result set there's only one number.
How do i add/authorize numbers to that list?
