Hey everyone 👋 I’m building a Vapi outbound agent using a Telnyx German number. The agent successfully places the call, but doesn’t react to what the customer says — it’s like it can’t hear them. However, in the Vapi call logs, I can see that both voices are recorded, so audio seems to be flowing in both directions. Does anyone have an idea what could cause this? Maybe something related to STT/TTS setup (Deepgram + OpenAI) or Telnyx RTP settings? Any tips would be super appreciated 🙏
