LYNC-SIP「413-請求實體太大」錯誤訂閱請求

我目前正試圖聯合兩個Lync域與中間一個自定義SIP代理。問題是，Lync服務器將回復「413 - 實體太大」，以便在通過代理服務器後訂閱來自其他Lync域的請求（msrtc-adrl-categorylist）。LYNC-SIP「413-請求實體太大」錯誤訂閱請求

但是，當我向SIP模擬器（SIP模擬器）發送了類似的消息時，即使它通過SIP代理，訂閱也會被接受。

這兩條消息非常相似。代理添加一條記錄路由並在From標籤末尾附加一個ID。它沒有把手放在身體上。

內容長度的差異是因爲SIPp在正文的末尾添加了一個CRLF，而Lync沒有。

我看不到任何請求的錯誤。以下消息記錄在目標域的Lync Edge上。

是否有人知道什麼可以觸發這個錯誤？錯誤信息並不是真的很有幫助...

被拒絕的郵件的From頭是'From：（注意** lyn1 ** instread ** lync1 **，它位於接受郵件的標題中）。它的目的是？一些SIP服務器會拒絕來自不正確域的消息 – tozka

這是一個錯誤。我爲這篇文章故意改變了域名。 – mdef

我終於設法發現了這個問題。

Lync服務器存儲「Call-ID」+「From tag」+「To tag」的「Dialog ID」。通過在「From tag」末尾附加一些額外的數據，「Dialog ID」的大小超過了其限制大小。
