我目前正在尝试将两个Lync域与中间的一个自定义SIP代理联合在一起。 问题是，前端服务器将回复“413 – 实体太大”以通过代理订阅来自其他Lync域的请求。
但是，当我向SIP模拟器SIPp发送类似的消息时，即使通过代理，订阅也被接受。
这两个信息非常相似。 代理添加logging路由，并在From标签末尾附加一个ID。 它没有得到它的手在身体上。
内容长度的差异是因为SIPp在正文的末尾添加了一个CRLF，而Lync没有。
我看不出有什么问题。 以下消息logging在目标域的Lync Edge上。

有人知道什么可以触发这个错误？ 错误信息在这里不是很有帮助…
一些帮助将非常感激！
谢谢
我终于设法发现了这个问题。
Lync服务器存储“呼叫ID”+“From tag”+“To tag”的“Dialog ID”。 通过在“From tag”末尾添加一些额外的数据，“Dialog ID”的大小超过了限制大小。
