Telnyx Voice API Endpoint Fix

I already have a JavaScript calling script built around the ai-besroxk flow that works perfectly with Twilio. When I switch the same code over to Telnyx, the call never completes—even though authentication and network connectivity look fine. My hunch is that I’m still pointing at Twilio-style URLs and need the correct Telnyx voice API endpoints wired in. What I need from you is a clean adjustment of the endpoint section of the code, along with any small configuration tweaks Telnyx requires. If you can confirm the right URLs from the Telnyx docs, update the script, and demonstrate a successful outbound call, that’s a win. Please return the updated JS file and a brief note (or comments in the code) summarising what you changed so I can follow along and maintain it myself later.
