JAIN SIP 未经授权的响应
JAIN SIP Unauthorized response
我正在 eclipse 环境中使用 JAIN SIP 库开发 SIP 客户端。
我无法获得授权。我还实现了 MD5 质询并向第二个 Register 函数添加了 Authorization。
授权凭证也是正确的，因为我用可用的 SIP 应用程序检查了它们。我可以用它注册和打电话。
这是初始化注册的代码

我比较了两个数据包，没有发现任何差异。我不明白为什么我没有获得授权。在这种情况下，localIP 和 SIPIP 也不同。
我认为问题可能出在端口上，但我没有在网上找到任何有关分配 rport 和 sipport 的帮助：5060。
我也想了解更多相关信息。
REGISTERs CSeq 1 和 CSeq 2 上的调用 ID 应该相同。它们与您的情况不同。
我正在 eclipse 环境中使用 JAIN SIP 库开发 SIP 客户端。
我无法获得授权。我还实现了 MD5 质询并向第二个 Register 函数添加了 Authorization。

我比较了两个数据包，没有发现任何差异。我不明白为什么我没有获得授权。在这种情况下，localIP 和 SIPIP 也不同。
我认为问题可能出在端口上，但我没有在网上找到任何有关分配 rport 和 sipport 的帮助：5060。 我也想了解更多相关信息。
REGISTERs CSeq 1 和 CSeq 2 上的调用 ID 应该相同。它们与您的情况不同。
