拿到问题先看log对时间点。一开始拿到log时以为问题点后面的log都有问题。但是看radio log没有打印null ，还有请求列表阻塞的日志。qcril log也有处理。但是qcril response 回的慢。
后面重点关注[9548]这个hangup命令。这个命令没有错，只是回的慢。其他的有错，应该是9548没完，也不会处理后续的。
本来想通过qmi命令确认挂机命令是否到modem侧。奈何过滤的qmi log竟然没有voice的。只好去看空口。呵呵：果真，网络回复慢啊。早知道一开始看空口log了。而且又看了被挂断方的空口，很快就断了。你说说，测试人员为啥不多备注一句被挂断方已经断了而挂断方让然无法挂断呢？这样就会先怀疑空口了。
命令成功到modem侧

但是网络没有回release，直到 02:39:29链路自动释放才释放通话。

再根据log和测试确认有问题的通话有几通，时间点。这个问题确认只有一通有问题。后面没有问题。
再贴一些相关log:
