Hi there! 👋 I understand how frustrating it can be when your assistant can't hear you during a call. I'm unable to diagnose the exact issue with your specific call ID without access to the detailed logs. However, I can definitely help you troubleshoot the one-way audio issue where your assistant can't hear you speaking. Based on the information I've found, here are several potential causes and solutions: ## Microphone Permissions and Settings - **Permission Issues**: The assistant may not have proper microphone permissions. This can result in a "No Microphone Permission" error or "customer-did-not-give-microphone-permission" message in logs [according to troubleshooting guides](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336782522859913226). - **Audio Input Quality**: Poor audio input quality can prevent the assistant from hearing you properly. Background noise can severely impact conversation ability [as mentioned in Vapi documentation](https://docs.vapi.ai/how-vapi-works). ## Voice Activity Detection (VAD) and Endpointing - **VAD Settings**: If incorrectly configured, the system might miss the beginning of your speech or cut off audio prematurely [based on user reports](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1316042862630146058). - **Endpointing Issues**: Endpointing decides when a user has finished speaking. Setting endpointing to 300 may improve quality [according to troubleshooting guides](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1338470163825033287). ## Configuration Settings - **Silence Timeout**: If
silenceTimeoutSeconds
is set too low, the system might cut off audio if you pause briefly [as documented in the API reference](https://docs.vapi.ai/api-reference/calls/create).
- **Background Denoising**: If there's high background noise and denoising is disabled (
backgroundDenoisingEnabled: false
), it might affect the assistant's ability to hear you [according to configuration guides](https://docs.vapi.ai/api-reference/assistants/create-assistant). ## Inbound Call Configuration - **Webhook Configuration**: Ensure that "a call comes in" is set to "webhook" and the URL is set to "https://api.vapi.ai/twilio/inbound_call" [based on user reports](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1343632206958166096). - **Incoming Assistant Configuration**: Verify that the incoming assistant is correctly configured to answer calls for your phone number [according to troubleshooting guides](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1333472116984778894).

Hey Steve, could you check the Call ID again? It doesn't contain any recording URL, so I cannot listen to the call recording.
