For users to call your application, you will need to provide them a Hoiio Number. Previously subscribing to a Hoiio Number has to be done manually via the Developer Portal, now we have added APIs that let your application subscribe Hoiio Numbers automatically. This means you can now subscribe to Hoiio Numbers on the fly and create applications where each user can have their own Hoiio Numbers!
The process of subscribing to a Hoiio Number is as follows: you first ask for a list of available Hoiio Numbers for a certain country, then tell us the number you want to subscribe to. You can extend an existing subscription by subscribing again.
