Fix Telnyx Call Failure

Job ID: 40434712

Budget: $10 – $30 USD

My broadcast phone system has suddenly stopped getting answers back from Telnyx. Calls leave the server but never receive the 200 OK, so nothing connects. I have already opened a ticket with Telnyx support, yet the problem persists.

Everything points to a mis-configured SIP trunk on the Telnyx side, though I also see permission-related errors when the application hits their API. I need someone who understands Telnyx inside out—SIP trunk provisioning, outbound/inbound call routing, API key scopes, webhooks, the works—to dive in, locate the exact fault, and bring the service back online.

Acceptance criteria
• Root cause identified and explained clearly.
• SIP trunk and any API permission issues resolved.
• Test calls (outbound and inbound) complete successfully with normal call quality.
• A short, step-by-step summary of the fix supplied so I can reproduce it if needed.

You will receive full portal access, server logs, and SSH if required. Let me know your experience with Telnyx (or similar providers) and how quickly you can start.
