java - javax.sip.SipException：发送请求时发生 IO 异常

Question

我想使用 Jain sip api 注册到 sip 服务器。但是，javax.sip.SipException: IOException occured while Sending Request返回错误“”。

如果我无法正确生成 sip 消息，则网络不可达：数据报发送失败。

输出我作为逻辑编写的代码中的 REGISTER SIP 消息似乎是正确的。我只是不能确定端口。

代码生成的REGISTRANT TICKET如下。请求：注册 sip：test.spoiler.com.tr：5060 SIP / 2.0 呼叫 ID：3235ae8a968869c2525bf1035d05d168@192.168.56.1 CSeq：1 注册来自：；tag = 2065198559 To: Via: SIP / 2.0 / UDP 192.168.56.1:50600 // 我也试过在这里写 Sip 服务器的 IP 地址 Max-Forwards: 70 Expires: 5 Content-Length: 0

My sip server that I want to connect to is: test.spoiler.com.tr
AOR address-> sip: test.spoiler.com.tr: 5060
UAS address -> sip: [e-mail]: 5060

我还同时将 UAS 地址指向了我要注册的 Sip 的用户。所以; toHeader-> fromHeader-> ; tag = 2065198559 我写了我的 sip 服务器地址，以便 Via 连接到第一个 sip 服务器。在正常情况下，它会获取本地主机上的 IP。虽然我尝试了本地主机 IP，但结果并没有改变。

javax.sip.SipException: IO Exception occured while Sending Request

我的库：
- javax.sip -> jain-sip-api 1.2.1
- javax.sip -> jain-sip-ri 1.2.244 - org.mobicents.slee.media -> media-rtp 1.0
- javax.media jmf 2.1.1e - org.zenframework.z8.dependencies.commons log4j-1.2.17 2.0

我如何得到 IO 错误。我该如何解决？当我浏览互联网时，我没有找到这个错误的解决方案。
