Record-Route标头被添加到如下所示的初始INVITE消息中。收到后 200 OK此请求，通过在SipServletResponse类中使用createAck（）方法创建ACK。 ACK消息的输出也如下所示。如您所见，47.168.150.15被添加到路由头中，该头最初作为Record-Route添加到INVITE。由于ACK消息在内部路由，因此不会发送到47.168.22.204。
下面的行是来自mobicents调试日志。 [org.mobicents.servlet.sip.message.SipServletRequestImpl]由于RR = Route :; lr
请求在内部进行我必须添加Record-Route标头才能接收会话的后续消息。
你知道为什么47.168.150.15被添加到ACK消息中吗？我试图从ACK中删除此地址并修改Record-Route标头但我无法成功。
提前致谢。 Hatke
