Hi there! I see you're having trouble connecting phone numbers from Telnyx to Vapi and getting an "Incorrect Telnyx Credential" error. I can't determine the exact cause of your specific issue without more details about your setup, but I can definitely help with troubleshooting steps and information about how to properly connect Telnyx with Vapi. Based on the documentation I found, here's how you can address this issue: ## Verify Your Telnyx Credentials First, make sure your Telnyx credentials are correct: - Check that your Telnyx account has the necessary permissions and is in good standing - Verify that the credentials you're using haven't been revoked - Check the "Authentication and Routing" tab in your SIP Trunking Connection in Telnyx [source](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1324828879667597424) ## Proper Integration Method It's important to note that direct import of Telnyx numbers into the Vapi dashboard might not be available. According to the documentation, Vapi supports importing phone numbers directly into the dashboard only from Twilio and Vonage [source](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1324828879667597424). For Telnyx, you'll need to use SIP trunking. Here's how: 1. Create a SIP Trunk Credential through the Vapi API:

curl -X POST https://api.vapi.ai/credential \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer your-vapi-private-api-key" \
    -d '{
        "provider": "byo-sip-trunk",
        "name": "Telnyx Trunk",
        "gateways": [
            {
                "ip": "sip.telnyx.com"
            }
        ]
    }'

[source](https://docs.vapi.ai/advanced/sip/telnyx) 2. Then create a Phone Number associated with the SIP trunk: ``` curl -X POST https://api.vapi.ai/phone-number \ -H "Content-Type: application/json" \ -H "Authorization: Bearer your-vapi-private-api-key" \ -d '{
