This guide provides a comprehensive overview of configuring the Vodia phone system with Telnyx phone service using Registration. It begins with setting up a Telnyx account, including purchasing a phone number and creating a connection with secure credentials. Once the connection is established, the guide walks you through provisioning your number and assigning it to the created connection. The outbound profile setup enables outbound calling through Telnyx, and Vodia PBX integration is simplified with automatic dial plans. Additionally, routing incoming calls to specific extensions or external URLs is covered, along with managing multiple DIDs through Vodia’s DID management.
