事实上，它根本没有返回任何响应，在沉默一段时间后（没有返回任何内容），控制台会显示“事务超时”。知道为什么会发生这种情况吗？我猜您的问题是： 您的联系人标题显示私人地址。请尝试在此处使用可公开路由的地址。（你可以使用STUN来发现你的公共广播或其他方式。）如果你正在通过B2BUA（又名会话边界控制器），它会为你重写这些。SIP中的防火墙和NAT穿越非常重要
此外，您的邀请中有内容长度，但您有内容吗？您忘记设置SDP内容了吗？事务超时对应于sip超时，应该是32秒。您得到这个408答案是因为您没有收到答案。这是由堆栈本身生成的自动应答，而不是由远程方生成的应答 你检查防火墙设置了吗？如果您的操作系统防火墙没有问题，您是否检查了家庭网关 注册和邀请请求是否发送到同一ip地址？你可以用它来检查
yohann与其与低级别的SIP打交道，不如尝试一种更高级别的框架，比如SIP servlet，它让您能够专注于核心业务逻辑？你甚至可以试试亚马逊AMI我已经编辑了我的主要帖子，以回应你的回答，请看一看！谢谢！：）嘿，约汉！谢谢你的回复。即使注册请求成功，防火墙是否可能阻止了某些内容？你知道我应该在防火墙设置中查找什么吗？对于Linux，wireshark还有其他选择吗？遗憾的是，Wireshark没有提供该程序的Linux版本。再次感谢你，尤汉！谢谢。编辑：Linux上有wireshark，我真蠢。我将检查请求发送到的IP并向您报告。对于防火墙问题，我同意。但是您应该检查REGISTER和INVITE请求是否发送到相同的实际ip地址。Wireshark可用于linux。如果您喜欢旧的工具，也可以使用tcpdump，但wireshark更方便用户。您应该使用linux分发包管理器安装新软件。在互联网上搜索更多关于这个的细节。我已经和Wireshark联系过了，由于某些原因，他们没有发送到相同的IP地址。知道他们为什么这么做吗？我必须更改哪个参数才能正确地将请求发送到IP？也许您应该尝试调用sip：6281386725319@sip.dialnow.com代替sip：6281386725319@dialnow.com
