Yesterday we had two customer calls spontaneously fail with reason "Silence Timed Out". This is hurting our reputation as a young company. Call IDs: - 1e69548e-2296-410b-80fe-d1514668767c - 3eb1b082-4381-4277-957c-3447d5c67620 Why did this happen? How can we avoid in the future?

Hi khalobert, The "Silence Timed Out" error occurs when a call is ended due to prolonged silence, indicating inactivity. To prevent this issue in the future, consider the following steps: 1. **Adjust Silence Timeout Settings**: Review and extend the duration before a call is terminated due to silence, if appropriate. 2. **Engagement Verification**: Ensure that any automated processes engage with the customer or assistant at intervals to prevent silence. 3. **Monitoring Tools**: Implement call monitoring or analytics to track silence patterns and adjust settings dynamically. 4. **Training**: If the silence is on the participant's side, provide guidance on avoiding pauses that may trigger the cutoff. By tweaking these settings and practices, you can reduce the occurrence of calls ending due to silence. You can find more details about this and other [call ended reasons on this page](https://docs.vapi.ai/calls/call-ended-reason). Please do let us know if this still persists.
