Description: 《Skype API应用范例》 ——
Skype是个非常优秀的IP电话通信工具，不但可以PC to PC，而且也可以PC to PSTN，当今非常盛行。Skype为了加快自己的发展全面开放了API，其实所谓的API不是真正的Win32 API函数，而是一系列消息的组合，我花了一个晚上从网上找到Skype API说明文档简单地实现了Skype通话和拨号以及发送文字聊天消息的简单功能，仅此达到抛砖引玉的目的。-"Skype API application paradigm"-- Skype is a very outstanding IP telephony communications tool, it can not only PC to PC, but also PC to PSTN, is very popular today. Skype to accelerate our development of open API, the so-called API is not really the Win32 API function, but a series of news portfolio, I spent a night on the Internet Skype API documentation simple to achieve Skype calls and dial-up chat and send text information simple function that alone to start a purpose.

Description: 在开发 VoIP 系统时，主要考虑的一个方面就是连接到模拟电话的接口。设计人员必须了解 PSTN 中存在的电话接口要求，因为它们必须在 VoIP 系统中得到支持。本文将重点介绍连接到标准 POTS 电话的两种最常用接口：Foreign eXchange Subscriber (FXS) 与 Foreign eXchange Office (FXO)。重点说明了设计人员在为 VoIP 小区网关的模拟电话接口提供支持时可能面临的某些挑战。-In the development of VoIP system, one aspect of the main considerations is connected to the analog telephone interface. Designers must understand the existing PSTN telephone interface requirements, because they are in the VoIP system must be supported. This article will focus on the standard POTS telephone connected to the two most commonly used interface: Foreign eXchange Subscriber (FXS) and Foreign eXchange Office (FXO). Focusing on the design staff in the Residential Gateway for VoIP analog telephone interface may provide support to some of the challenges faced.
