# NO_ANSWER

> This event triggers when a call isn't answered within the ringing time and the AI Agent hangs up automatically.

This event serves to indicate that the call wasn't answered within the specified ringing time.

When the AI Agent rings for the number of seconds you specify in the [Transfer Node](/ai/agents/develop/node-reference/voice/voice-gateway/transfer) settings and there is no response during this ringing time, the AI Agent hangs up the call.
