英文:
Why do i get two "407 Proxy Authentication Required" SIP responses?
问题
我正在使用Golang和Freeswitch开发软电话解决方案。注册功能正常，我可以在Freeswitch上看到我的软电话代码已注册。我还可以从另一个软电话（3CX）向我的代码发送INVITE请求。但是，如果我尝试呼叫3CX，我总是收到两个"407 Proxy Authentication Required"错误。
我期望的流程如下：
- 发送INVITE请求
- 收到"Proxy Authentication Required"错误
- 将认证信息放入第二个INVITE请求中并重新发送
- 建立呼叫连接
我实际得到的流程如下：
- 发送INVITE请求
- 收到"Proxy Authentication Required"错误
- 将认证信息放入第二个INVITE请求中并重新发送
- 收到"Proxy Authentication Required"错误
- 没有进一步的操作
（我删除了SIP Body（offer）因为它太大）
以上是您提供的日志信息，其中包含了发送和接收的SIP请求和响应。
英文:
I am working on a softphone solution with Golang and Freeswitch. The register works and on Freeswitch I can see my softphone code is registered. I also can send an INVITE from a other softphone (3CX) to my code. But if I try to call the 3CX i always get two "407 Proxy Authentication Required".3
What I expect:
- Send INVITE
- Receive the Proxy Authentication Required
- Put the Auth into the second INVITE and send again
- Call will be setup
What I get:
- Send INVITE
- Receive the Proxy Authentication Required
- Put the Auth into the second INVITE and send again
- Receive the Proxy Authentication Required
- Nothing
(I deleted SIP Body (offer) because it's to big)

好的，现在我找到了我的错误。我写成了Proxy-Authenticate而不是Proxy-Authorization。但是现在我得到了一个合并的请求响应。所以Freeswitch将其视为重复的请求。
英文:
Okey. Now i found my error. I have written Proxy-Authenticate instead of Proxy-Authorization. But now i am getting an Request merged response. So the Freeswitch sees it as a doublicated request.
