推荐答案

您无法从代码中执行任何操作。客户端的路由器必须配置为将指定IP和端口上的流量转发到网络内的系统。如果您可以控制当前正在运行的语音，则可以添加UPnP代码进行设置。如果没有，您无法从最终选择目标系统。

You can't do anything from your code. The router on the client side has to be configured to forward the traffic on the specified IP and port to the system inside the network. If you have control over the voice the current is running them you can add UPnP code to set this up. If not, there's nothing you can do to select the target system from your end.
