The typical IP PBX can also switch calls between a VoIP user and a traditional telephone user, or between two traditional telephone users in the same way that a conventional PBX does.
I find this pretty amazing, that you can switch between two architecture models (REST vs. SOAP) yet still code the same way for the other 90% of an application.
我发现一个神奇之处就是，你可以在两个架构模型(REST vs . SOAP)之间切换，而应用程序中90%的代码都是完全相同的。
