I recently purchased a Telnyx number and intent to test this as a substitute to Twilio. I've followed the Docs and got the number inside of VAPI but receive 'An error occurred in this call: call.in-progress.error-providerfault-outbound-sip-403-forbidden'. I spoke with Telnyx and they confirmed the SIP Trunking is setup ok, I'm running out of options and things to check. Any support is welcomed. Thanks

Hi AJH, To resolve the 403 error with outbound calls using your Telnyx number, ensure the following configurations are in place: 1. Configure Telnyx Account: - Log in to the [Telnyx Portal](https://portal.telnyx.com). - Create or edit an Outbound Voice Profile. - Under “Connections and Applications,” add Vapi as a connection. - Save these changes to enable outbound calling with your number. 2. Check Vapi Dashboard Settings: - Ensure your Telnyx number is correctly imported into the Vapi dashboard under the Phone Numbers tab. - Ensure that the right phone number and outbound configurations are used when setting up calls from the Vapi platform. For detailed steps, you can refer to the [Import number from Telnyx](https://docs.vapi.ai/telnyx) guide. If the setup is correct and the issue persists, please verify the authentication tokens or any additional network configurations that might be causing the issue. If this doesn’t resolve the issue, please let us know and we’ll be happy to step in and assist further.

I recently encountered this issue. It wasn't apparent where the appropriate webpage was located in the Telnyx Portal so here's a direct link: https://portal.telnyx.com/#/outbound-profiles
