### Answer The

unknown-error

status you're encountering, as indicated by the call log with ID

225a4365-f95e-426e-aae2-2d0ad6ebe8c4

, is a general error that signifies an unexpected issue occurred during the call process. This type of error doesn't provide specific details on what went wrong, making it challenging to diagnose without further investigation into the system's internal logs or operations [(1)]() . Given the components involved (Deepgram for transcription, GPT-3 for the model, and ElevenLabs for voice synthesis), and the issue you've described (the introduction message plays but then no further action occurs, and the expected silence timeout doesn’t trigger), a few potential areas of concern could be: 1. **Integration Issues**: There might be a problem with how these services are integrated within your setup, potentially causing a failure after the initial interaction. 2. **Configuration or Limitations**: There could be a misconfiguration or a limitation reached with one of the services (Deepgram, GPT-3, or ElevenLabs) that's not immediately apparent. 3. **Silence Timeout Configuration**: The issue with the silence timeout not occurring as expected might indicate a problem with how the silence detection or timeout configuration is set up within your Vapi assistant settings. Unfortunately, the information sources provided do not detail a direct way to resolve

unknown-error

issues or investigate specific call IDs. In these situations, a review of the configuration in the Vapi dashboard, and potentially reaching out to the support or technical teams of the involved services (Deepgram, OpenAI for GPT-3, and ElevenLabs), might be necessary to identify and resolve the underlying issue. It's also beneficial to review any logs or error messages provided through Vapi's dashboard or the associated services

for any clues on what might be causing the issue post the initial message playback. Given the nature of the error and the complexity of the integration, closely examining each component's interaction within the call flow might help pinpoint the source of the problem.

okay it turned out that my deepgram api key expired. for the last 12 hours i didn't even think this was an option because i expected this to be a very standard error to not result in 'unknown-error'.
