为什么 jain sip return 481 收到再见？
why jain sip return 481 on received bye?
我使用 Jain Sip 创建一个 sip 应用程序。它可以send/receiveINVITE/ACK/BYE，必要时用SDP发回响应。
但是当它收到对方的 BYE 时，Jain Sip 会抛出一个 481。
我试图弄清楚发生了什么事一个星期仍然不明白。
我使用来自传入请求的 ServerTransaction.sendResponse 有状态地发送响应。自动对话已打开。
这里是完整的源码（界面我用的是swing）

正在查看更新的日志。
您发送邀请 From: <sip:127.0.0.12:5060>;tag=2074886745
对端再次发送BYEFrom: <sip:127.0.0.12:5060>;tag=2074886745
端点代表同一地址发送消息 <sip:127.0.0.12:5060> 这是错误的。您的远程方应发送 From: <sip:alice@127.0.0.11:5060>;tag=dqixl8jjv0w。呼叫段 ID 倒序，因此未找到。
我使用 Jain Sip 创建一个 sip 应用程序。它可以send/receiveINVITE/ACK/BYE，必要时用SDP发回响应。 但是当它收到对方的 BYE 时，Jain Sip 会抛出一个 481。 我试图弄清楚发生了什么事一个星期仍然不明白。
我使用来自传入请求的 ServerTransaction.sendResponse 有状态地发送响应。自动对话已打开。
