Hi team, I’m experiencing a one-way audio issue in my setup using Telnyx for calling and Vapi for AI assistant integration. - The call is successfully established from a US number via Telnyx. - The callee can hear the assistant clearly. - However, the assistant cannot hear the callee's voice at all. - Vapi’s call recordings show no or very minimal audio from the callee’s side. Telnyx has confirmed that everything is working fine on their end, including proper RTP flow. On the Vapi side, I’m seeing: - No detectable input audio from the callee - Multiple [ERROR] Your server rejected 'speech-update' webhook messages with 400 status I'd appreciate help investigating: - Is Vapi successfully receiving RTP audio from the Telnyx call leg (callee side)? - Could the webhook errors be preventing the assistant from accessing input audio? - Are there any logs or diagnostics to confirm if Vapi is receiving media from the callee? Let me know what further details you need from my end to help troubleshoot this. Thanks!
