Integrate Yeastar P-Series Cloud Edition with Telnyx Fax

By integrating Yeastar P-Series Cloud Edition with Telnyx Fax, employees within your organization can send and receive faxes instantly and securely over the Internet - directly from their own Linkus Desktop or Web Client.

Introduction

Yeastar P-Series Cloud Edition supports the integration with Telnyx to enable Internet-based faxing, allowing PBX extension users to send and receive faxes through Telnyx's reliable communications network.

The integration is implemented using Yeastar PBX Webhook and Telnyx Fax API V2.
  • When an extension user sends a fax from Linkus, Yeastar PBX calls Telnyx API to submit the fax for delivery.

  • When a fax arrives at Telnyx fax number, Telnyx sends a webhook notification to Yeastar PBX. PBX then retrieves the fax file via API and delivers it to the designated extension users' Linkus.

You can easily set up the integration by following the instructions below:

  1. Obtain Webhook URL from Yeastar PBX.
  2. Create the necessary resources and obtain the required credentials from Telnyx.
    • An API Key to authenticate your account and access Telnyx API endpoints.
    • An Outbound Voice Profile to initiate outbound fax traffic.
    • A Fax-enabled Phone Number for sending and receiving faxes.
    • A Fax Application to manage inbound and outbound fax traffic.
  3. Fill in the obtained credentials in Yeastar PBX, then configure fax-related settings.
