It looks like it still waiting for you to say something, even if you were the last one to say something. I made a couple test voice calls and if you speak again before the silence time out, continues fine, but if you don't say anything else after your initial interaction it ends the call with silence. If access the assistant via chat works just fine. Please Advice Call ID: 4ea9d773-c549-43e0-bc6a-30a33f484351

Thanks for sharing the details. Based on the documentation, if the assistant goes silent after the initial interaction, it could be due to the "firstMessageMode" setting or missing "firstMessage" in your assistant configuration—by default, the assistant should speak first, but if not set, it waits for the user to speak ([Vapi docs](https://docs.vapi.ai/api-reference/assistants/update)). Could you confirm if your assistant's "firstMessageMode" is set to "assistant-speaks-first" and that a "firstMessage" is specified in your configuration? This will help narrow down the cause of the silence. Source: - [Vapi API Reference: Update Assistant](https://docs.vapi.ai/api-reference/assistants/update)

Agent is set to speak first, and it does. The problems is that if I ask the agent a question that the answer will be in a tool (in this case its a query tool with a txt file) it jsut goes silent until the call ends due to silent or I speak again.

Hi Colson, If your assistant is going silent after calling a tool while chat functions properly, it may be related to the handling of the tool.completed message or the configuration of your assistant messages. Here are a few things to check: 1. **tool.completed Message**: Ensure your assistant is properly set to handle the
tool.completed
message type. This helps in notifying when a tool has finished executing. You can find more details in our [April 26, 2025 changelog](https://docs.vapi.ai/changelog/2025/4/26). 2. **Customizable Messages**: Utilize the
message
property in
ToolCallResult
to define custom messages for when a tool completes or fails. This may help maintain interaction continuity (see the [April 26, 2025 changelog](https://docs.vapi.ai/changelog/2025/4/26) for more information). 3. **Non-Streaming Chat Context Management**: If this issue occurs in a non-streaming chat environment, ensure the context is being managed correctly using
previousChatId
, as outlined in the [Non-streaming chat documentation](https://docs.vapi.ai/chat/non-streaming). Adjusting these configurations should help in resolving the silence issue. Let me know if you need further assistance.
