问题内容

我正在使用 golang 和 freeswitch 开发软件电话解决方案。注册器工作正常，在 freeswitch 上我可以看到我的软件电话代码已注册。我还可以从其他软件电话 (3cx) 向我的代码发送邀请。但如果我尝试致电 3cx，我总是会收到两个“需要 407 代理身份验证”。3

我的期望：

发送邀请
接收所需的代理身份验证
将 auth 放入第二个 invite 中并再次发送
即将建立通话

我得到了什么：

发送邀请
接收所需的代理身份验证
将 auth 放入第二个 invite 中并再次发送
接收所需的代理身份验证
没什么

（我删除了 sip body（优惠），因为它太大了）
