Question

Asterisk表现还不错，但最近未能将再打包发送给来电设备。

设备B向设备A发起SIP呼叫，设备A在1分钟后向设备A发送SIP再见报文。

Asterisk应该将再见数据包发送给来电者的IP地址和端口号，但端口号不同。

来电者IP - 1000@175.XXX.49.162：9194

来自服务器的SIP再见数据包目的地 - 100@175.XXX.49.162：1439

你看到了什么问题吗？

Answer 1

您需要在INVITE消息中找到联系人。 REG联系人表明我在这里可用。 INVITE中的联系人意味着此会话/对话框将此所有未来请求发送到此IP：端口。

查看IP：用于发送BYE的端口在哪里，你应该能够知道它发生了什么。

Asterisk将SIP bye数据包发送到错误的目的地
