Logs showing ended reason "Assistant Ended Call" when call ended reason is "customer-ended-call"

We have lots of calls in our logs that are only lasting 6-7 seconds before they randomly end with reason "Assistant Ended Call". Further inspection into the logs reveals the tool call like this: 
{
    "role": "tool_calls",
    "time": 1758636590435,
    "message": "",
    "toolCalls": [
        "0": {
            "id": "hook-function-call-c6dee378",
            "type": "function",
            "function": {
            "name": "endCall",
            "arguments": "{\"callEndedReason\": \"customer-ended-call\"}"
            }
        }
    ],
    "secondsFromStart": 11.016
}


The callEndedReason here is always: "customer-ended-call". Does this mean the customer hung up, and if so, why is the Ended Reason showing up as "Assistant Ended Call"?
