Hoiio API prov

The Voice API component of Hoiio API provides developers access to telephony services in more than 200 countries around the world. You will be able to initiate phone calls to any mobile phones, land lines or create call conferences just by making an API request to our servers.

You can connect 2 phones using the Call API, or connect multiple phones using the Conference API.

This API will dial out to 2 destination number and connect them together in a phone conversation.

Hoiio will make a call to the first number. After the call is answered, Hoiio will make another call to the second number. While the second number is ringing, the party at the first number will hear the standard ring tone. When the party at the second number answers the call, both parties will be able to talk to each other.

Hoiio API does not support destination to short code, toll free, premium or emergency numbers.
