Pyhthonpjsip如何识别接收器已断开呼叫

Question

我正在使用(Python PJSUA(从我的树莓派进行调用。 如果接收器已断开连接。 我无法识别呼叫已断开连接。我打算为陆地电话到手机VoIP呼叫转移设备创建此内容。我没有编写完整的代码，因为我无法解决这个基本问题。那么我如何识别接收器(安卓手机(断开通话

while in_call:
if self.call.info().state == pjsua.CallState.DISCONNECTED:
in_call = False
break
pass

'

此方法不起作用。 我的程序在呼叫者断开连接后退出

完整代码如下

current_call.hangup()

更改为

if self.call.info().state == pjsua.CallState.CONFIRMED:
"your statements"
if self.call.info().state == pjsua.CallState.DISCONNECTED:
"your statements"

ELIF 语句不会在您的情况下标记。

您必须将其从"已确认"状态中移出

while in_call:
if self.call.info().state == pjsua.CallState.DISCONNECTED:
in_call = False
break
pass

self.call.hangup()
in_call = False

因为当呼叫断开连接时，状态将更改为已断开连接
