我所有的呼叫建立和终止排列都在起作用，除了一个。
当呼叫者挂断电话时，被呼叫者上的RtcSession会触发“结束”事件，在该事件中我调用RtcSession.terminate（），但这会引发异常“无效状态8”。我留下的红色录制图标仍显示在Chrome标签上，并且页面上的元素仍在计时。 我应该在“结束”事件处理程序中采取什么措施来正确关闭和释放音频通道？
代码和日志输出...
'ended': (e: EndEvent) => {
console.log('[cs71] incoming call ended with cause: ' + e.cause, e, rtcsession);
rtcSession.terminate();
}
