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>

}
}
5.2 测试代码
java
@Test
public void call() {
AliYunCallService aliYunCallService = new AliYunCallService();
try {
System.out.println("StartBack2BackCall"+aliYunCallService.startBack2BackCall("131********","151********","0102157****").toMap());
System.out.println("GetCallDetailRecord"+aliYunCallService.getCallDetailRecord("job-57********").toMap());
} catch (Exception e) {
throw new RuntimeException(e);
}
}
