Java：阿里云联络中心“双呼A”功能系统接入

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

        }catch (Exception e){
            e.printStackTrace();
        }
    }

    public TeaModel startBack2BackCall (String caller,String callee,String broker) throws Exception {

                .setContactId(contactId);
        return aliYunCallClient.getCallDetailRecord(request).getBody();
    }
   

}

 5.2 测试代码

    @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);
        }
    }
