我正在编写一个 SIP 服务器，我让它接听电话，然后将它们连接到 voip 电话，问题是当你挂断 voip 电话时，我的手机没有的 BYE 消息的转发出现问题结束通话。

这是 SIP 消息日志（我用 1234 替换了我的服务器电话号码，用 5678 替换了我的手机电话号码，我的服务器的 IP 已替换为 x，我的 voip 电话的 IP 已替换为 y） -

您可能想检查警告标头的值是什么意思。有一些自定义消息“嘈杂的反馈告诉”......这是非常特定于应用程序的。当事务超时过期时，请求超时消息通常由堆栈模拟。这可能意味着您对 174.37.45.134:5060 的 BYE 请求无法到达目的地。当原始 BYE 请求格式不正确而另一方忽略它时，也可能出现这种情况。

您是否尝试过使用SIPp在本地调试您的服务器？
您还可以运行 Ethereal ( Wireshark ) 来检查您的流量。

“via_cnt==1092”也很可疑。

顺便说一句，您似乎正在构建一个 B2BUA，因为您甚至在向本地电话 (1234) 发送邀请之前就接受了来自外部的呼叫。如果本地电话接受不同的参数，接受不同的编解码器等，您会被搞砸，因为您告诉本地电话将媒体直接发送给原始呼叫者。他们真的应该都将他们的媒体发送到您的服务器，这将中继（或如果需要转码）。

如果您不想这样做（即您不想充当媒体中继和可能的转码器），则需要将 INVITE 转发到本地电话，然后转发任何响应等。基本上更多地充当 SIP代理服务器而不是 SIP B2BUA。

我建议检查调用分支是否接受 BYE 请求（看起来它接受但......）以及它如何处理这个请求。您真正需要的是来自 174.37.45.134 的类似日志。似乎问题出现在 .134 之后（超时由 .134 生成）。

顺便说一句，至于第一眼，我发现您违反了几条基本的呼叫处理规则，这可能会让您陷入困境：-您缺少尝试对发起呼叫腿的响应。如果发起者的 SIP 堆栈真的等待它，它可能会导致呼叫 ID 没有真正记录。是的，这是错误的行为，但我们生活在现实世界中。标准说要尽快尝试响应（甚至在您进行路由之前，就在呼叫身份验证之后 - 您甚至在向被叫方发起传出邀请之前就已与呼叫方完全建立呼叫会话。这是错误的逻辑。至少因为在失败的情况下拨出电话的始发者将被计费。

如果您可以快速完成此操作，我建议您先修复呼叫设置顺序。无论如何，您都需要这个，并且有可能解决呼叫终止问题：

如果您希望符合 RFC 3261，则您发送的“Via”标头必须包含可选（！）“branch”参数。

请参阅 RFC3261 ss 20.42：

尽管本规范要求所有请求中都存在分支参数，但标头字段的 BNF 表明它是可选的。这允许与不必插入分支参数的 RFC 2543 元素进行互操作。

RFC 3261 规定在 To 和 From 字段中关联的数字 (URI) 保持不变。如果涉及 NAT'ing，IP 可以更改，但数字必须保持不变。如果您注意到，BYE 标头中的“To”和“From”字段被交换，使其成为格式错误的数据包。
