Bring Your Own Number

Last updated on 2025/03/12

The Bring Your Own Number (BYON) API allows you to incorporate voice calling capabilities using a T-Mobile phone number into your application. Whether you're building a SIM call forking system, a click to call application that uses your customer’s SIM line, or any other communication-based application, the BYON voice calling API will help you do it.

Using WebRTC, your application will be able to use the BYON API to make and receive voice calls through over-the-top VOIP internet data connections, as well as placing calls on hold, resuming them, and ending calls, all via simple API requests.

To get started, you need:

  1. An active DevEdge account

    Create a DevEdge account, if you haven't already.
