为何贾恩啜饮481收到再见？

我使用Jain Sip创建一个SIP应用程序。它可以发送/接收INVITE/ACK/BYE，并在必要时用SDP发送回应。但是当它从另一边收到BYE时，Jain Sip会抛出一个481。我试图弄清楚发生了一个星期，但仍然不明白。为何贾恩啜饮481收到再见？

我通过使用来自传入请求的ServerTransaction.sendResponse有状态地发送响应。自动对话框已打开。

这里是整个源代码（我使用Swing的接口）

欢迎来到SO。也许这会有助于显示你的代码。 –

你能发布完整的调试日志或至少是SIP消息吗？ –

我们必须至少看到带有SIP消息的BYE。用pcap工具记录它或启用调试日志（最好）。您也不应该this.sipProvider .getNewServerTransaction（请求）的ACK –

看着更新的日志。

您发送INVITE From: <sip:127.0.0.12:5060>;tag=2074886745

远程端发送BYE代表相同的地址<sip:127.0.0.12:5060>这是错误的再次From: <sip:127.0.0.12:5060>;tag=2074886745

中的端点发送消息。您的远程方应发送From: <sip:[email protected]:5060>;tag=dqixl8jjv0w。呼叫线路ID反向，因此未找到。
