我想使用Jain sip api注册到sip服务器。但是，返回错误“ javax.sip.SipException: IOException occured while Sending Request”。
如果无法正确生成Sip消息，则说明网络无法访问：数据报发送失败。
输出我写为逻辑的代码中的REGISTER SIP消息似乎是正确的。我只是不确定端口。
该代码产生的注册凭证如下。 要求：注册sip：test.spoiler.com.tr：5060 SIP / 2.0 呼叫ID：3235ae8a968869c2525bf1035d05d168@192.168.56.1 CSeq：1个寄存器 来自：；标签= 2065198559 至： 通过：SIP / 2.0 / UDP 192.168.56.1:50600 // //我也尝试在此处写入Sip服务器的IP地址 最大前进：70 过期：5 内容长度：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: 800@test.spoiler.com.tr: 5060
我还指出了UAS地址作为我想同时注册的Sip的用户。所以; toHeader-> fromHeader->;标签= 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，它会在本地主机上获取IP。 尽管我尝试了本地主机IP，但结果没有改变。

javax.sip.SipException: IO Exception occured while Sending Request
我的图书馆：

如何获取IO错误。我该如何解决？通过互联网查看时，找不到该错误的解决方案。
