As highlighted in the Known Limitations, during the alpha period it will not be possible to purchase BlueVia Voice Numbers. Instead we are giving you a set of Numbers in each of the supported alpha territories.
When BlueVia Voice Numbers are available to purchase the Available Numbers Collection will provide a mechanism to access the details of these Numbers. You will then be able to purchase these numbers, and add them to your account using Account Number Collections and Account Numbers.
