用于发短信，拨打电话的网站接口

云之讯：http://www.ucpaas.com/price

中国网建：http://sms.webchinese.cn/api.shtml  测试的时候发现短信达到延迟太久，没办法使用。

云通讯：http://www.yuntongxun.com/

 我使用了云之讯来作为我的通讯第三方，平台提供了详细的接口说明和资费说明。

到他们官网可以下载到C#的demo，在我开发的过程中发现他们的demo缺少了一个语音电话，

根据他们的协议要，写了一个《云之讯语音通知协议》

 /// <summary>
            /// 电话语言提醒
            /// </summary>
            /// <param name="toPhone">被叫号码，可以是正常手机号码、固定号码，被叫为座机时需要添加区号，如：075512345678。</param>

                {
                    throw e;
                }
            }

 

以上都提供了demo。使用起来比较方便。
