call.BeginTransfer工作50％ [英] call.BeginTransfer works 50%
问题描述
更新：我在5台不同的计算机上运行服务，所有工作都很好100％，除了一个工作50％。
什么可以导致call.BeginTransfer工作50/50？ 有时是有效的，有时候不是吗？
What can cause to call.BeginTransfer to work 50/50 ? sometimes works, and sometimes not ?
相同的数字，差异数，许多测试，
same number , diffrents number , many tests ,
（在我的发展环境中，它正在100％工作（永远有效），在问题
(On my develpoment environment it's working 100% (allways works) , on other environment which the problem
发生的其他环境中， 与开发环境完全无关 ， 它是50/50）
occure and is not related at all to the development environment, it's 50/50 )
* BackToBack可以像普通电话一样转移吗？使用TwoParty呼叫创建BackToBack呼叫，然后从TwoParty呼叫断开

推荐答案
为了澄清，你试图在其中一个上进行转移打电话给BackToBackCall？在其中一台开发机器上，传输失败的时间是一半？
To clarify, you're trying to do a transfer on one of the call legs of a BackToBackCall? And on one of the development machines the transfer fails half of the time?
您可以做的一件事是在前端服务器上运行OcsLogger.exe并获取S4和SipStack日志做转移。由于转移过程中有几个步骤，因此可以让您更清楚地了解到底出现了什么问题。
One thing you could do to start is run OcsLogger.exe on the Front End Server and get S4 and SipStack logs while doing your transfer. That'll give you more visibility into what exactly is going wrong, since there are several steps in the transfer process.
