Currently we only support purchase of US and Canada numbers and support making calls to 15 countries. If you are looking to use numbers from other countries, or to make calls to more countries, or to use your own telephony provider, check out the Custom Telephony guide.
From Dashboard
Navigate to VoIP Administration in the top nav, then select Phone Numbers.

From API
Check out the Create Phone Number API Reference for all the parameters you can use programmatically. Phone numbers are yours once purchased, and can be used indefinitely. You can assign different inbound and outbound agents to the number. If you don’t want users to be able to call this number (e.g. you are doing outbound only and don’t want callbacks), you can leaveinbound_agent_id unset.
