### Answer The call ending with 'customer-did-not-answer' in the middle of a conversation is likely due to Vapi's voicemail detection or other configuration settings. This specific issue has been observed before, particularly with voicemail detection settings. To address this: 1. **Disable Voicemail Detection**: If you haven't already, try disabling voicemail detection in your assistant's configuration. This can prevent the call from being mistakenly identified as unanswered:

json
   "voicemailDetectionEnabled": false

2. **Check Other Settings**: Ensure that other settings like

voicemailMessage

,

firstMessageMode

, and

backchannelingEnabled

are correctly configured to avoid interruptions during active calls [(1)]() , [(2)]() , [(3)]() . Reviewing other similar cases on Discord, disabling specific voicemail detection settings has resolved this issue for others, [(4)]() . If the issue persists, inspect the detailed call logs and configurations for anomalies or misconfigurations.
