1.背景
最近公司做的项目需要在线支持拨打虚拟电话给联系人，就对阿里云呼叫服务(云联络中心)进行调研测试。本文主要针对“双呼A”这一功能后端对接进行简单说明，有问题欢迎一起交流
2.准备工作
- 阿里云账号(个人/企业)
- 开通云联络中心->进入云联络中心管理控制台
- 个人账号: 创建实例
- 企业账号: 可先创建体验版演示实例
具体开通参考：如何开通和使用云联络中心_云联络中心(Cloud Contact Center)-阿里云帮助中心
3.双呼A接口
双呼和传统的双方通话不同，主叫并不直接呼叫对方，而是通过一个背靠背代理（Back to Back Agent），背靠背代理首先呼叫主叫方，接通后，再呼叫被叫方，然后把二者拉进一个会场。在这种方式下，由于每个呼叫的所有消息流经背靠背代理，因此服务提供商可以据此提供增值服务，比如计时、录音、隐藏真实号码等等。
4.JAR包
<!-- AliYun 阿里云联络中心--> <dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.8.21</version> </dependency> <dependency><groupId>com.aliyun</groupId><artifactId>ccc20200701</artifactId><version>2.27.1</version> </dependency>
