Overview

Telnyx is a cloud communications platform that provides programmable voice via its Call Control API. Dograh AI’s Telnyx integration uses Call Control plus WebSocket media streaming to power your voice agents.

​
Prerequisites

Before setting up Telnyx integration, you’ll need:
  • A Telnyx account
  • An API Key from the Telnyx Mission Control Portal
  • A Call Control Application (its connection_id is what Dograh stores)
  • At least one Telnyx phone number assigned to that Call Control Application
  • Dograh AI instance running and accessible

​
Configuration

​
Step 1: Get Telnyx Credentials

  1. Log in to the Telnyx Mission Control Portal
  2. Navigate to API Keys and create (or copy) an API Key
  3. Navigate to Call Control → Applications and create (or open) the application you’ll use with Dograh
  4. Copy the application’s Connection ID (Call Control App ID)
  5. Navigate to Numbers → My Numbers and assign your phone numbers to that Call Control Application

​
Step 2: Configure in Dograh AI

  1. Navigate to /telephony-configurations and click Add configuration
  2. Select Telnyx as your provider
  3. Enter your credentials:
    • API Key
    • Call Control App ID (Connection ID)
  4. Click Save Configuration
  5. Open the configuration you just created and add at least one phone number (with country code in E.164 format, e.g. +1234567890). The default caller ID is used for outbound calls.

​
Step 3: Test Your Configuration

  1. Create a test workflow
  2. Click “Call” to verify connection
  3. Check call logs for successful connection

​
Inbound Calling Setup

Telnyx delivers inbound webhooks at the Call Control Application level — the webhook URL is configured once on the application, and applies to every number assigned to it. When you save an inbound workflow on a phone number, Dograh automatically pushes the webhook URL to your Call Control Application’s webhook_event_url (provided the credentials are correct).

​
Step 1: Assign an Inbound Workflow to the Phone Number

  1. Go to /telephony-configurations and open your Telnyx configuration
  2. In the Phone numbers section, edit the number that should receive inbound calls
  3. Set its Inbound workflow to the agent that should answer
  4. Save

​
Step 2: Verify the Webhook URL on the Call Control Application

  1. Go to Call Control → Applications in the Telnyx Portal
  2. Open the application whose Connection ID you configured in Dograh
  3. In Webhook Settings, confirm:
    • Webhook URL is set to: https://api.dograh.com/api/v1/telephony/inbound/run
    • HTTP Method is POST
  4. Make sure the phone numbers you want to use for inbound are assigned to this application
    Dograh pushed this URL automatically when you saved the inbound workflow in Step 1. The same URL is shared across every number on the Call Control Application — Dograh matches the inbound call to the right agent using the called number’s inbound workflow assignment. If the field is empty, shows a different URL, or Dograh surfaced a sync warning on save, the auto-push failed — most often because the API Key or Connection ID in Dograh is incorrect. Paste the URL into the field yourself, set the method to POST, and save. On self-hosted Dograh, replace api.dograh.com with your backend domain.

​
Step 3: Verify Setup

  • Ensure your Dograh AI instance is publicly accessible
  • Verify any firewalls allow Telnyx’s IP ranges

​
Test Inbound Calling

  1. Call your configured Telnyx phone number from another phone
  2. Verify your Dograh AI voice agent answers and responds
  3. Check call logs in both Dograh AI dashboard and Telnyx Portal

​
Troubleshooting

Ensure phone numbers include country code in E.164 format: +1234567890
  • Verify the API Key is correct and active - Check for extra spaces in the key - Ensure the key hasn’t been revoked in the Telnyx Portal
  • Telnyx signs webhooks with Ed25519 - confirm the public key on the application hasn’t changed - Verify the webhook URL matches what Telnyx sends - Check if you’re behind a proxy that modifies request bodies
  • Verify WebSocket connection is established - Check firewall rules for WebSocket traffic - Ensure audio pipeline is configured correctly
  • Verify the Call Control Application’s webhook URL is set to https://api.dograh.com/api/v1/telephony/inbound/run - Ensure the webhook URL is publicly accessible from the internet - Confirm the called number is assigned to the same Call Control Application whose Connection ID is configured in Dograh - Confirm the called number exists in your Dograh telephony configuration and has an Inbound workflow assigned - Verify Dograh AI instance is running and responding
  • Confirm the phone number has an Inbound workflow assigned in /telephony-configurations - Verify the API Key matches the one stored in your Dograh telephony configuration - Verify WebSocket connection establishes successfully - Review call logs for error messages

​
Best Practices

  • Test your configuration with a single call before running campaigns
  • Monitor the Telnyx Portal for usage and billing
  • Use a dedicated Call Control Application for Dograh so the shared webhook URL doesn’t conflict with other systems
