FreeSWITCH Java ESL

环境:Window/Eclipse/FreeSWITCH-1.6.19源码

Java ESL调用FreeSWITCH发起呼叫

1:FreeSWITCH对外连接配置:

    修改D:\VS\freeswitch-1.6.19\Win32\Debug\conf\autoload_configs\event_socket.conf.xml文件,如下:


  
    
    
    
    
  

     listen-ip:FreeSWITCH服务器IP地址

     password:随便写

2:JAVA调用FreeSWITCH:

    需要Jar包:org.freeswitch.esl.client-0.9.2.jar、slf4j-api-1.7.25.jar

package com.fs;

import org.freeswitch.esl.client.IEslEventListener;
import org.freeswitch.esl.client.inbound.Client;
import org.freeswitch.esl.client.inbound.InboundConnectionFailure;
import org.freeswitch.esl.client.transport.event.EslEvent;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class TEST {
	private static final Logger log = LoggerFactory.getLogger(TEST.class);
	/**
	 * host/port/password配置在D:\VS\freeswitch-1.6.19\Win32\Debug\conf\
	 * autoload_configs目录event_socket.conf.xml文件中
	 */
	private static String host = "127.0.0.1";
	private static int port = 8021;
	private static String password = "fs";

	public static Client inBand() {
		final Client client = new Client();
		try {
			client.connect(host, port, password, 20);
		} catch (InboundConnectionFailure e) {
			log.error("Connect failed", e);
			return null;
		}
		// 注册事件处理程序
		client.addEventListener(new IEslEventListener() {
			public void eventReceived(EslEvent event) {
				// System.out.println("Event received:" + event.getEventHeaders());
				if (event.getEventName().equals("CHANNEL_ANSWER")) {
					// 呼叫应答事件
					System.err.println("CHANNEL_ANSWER"); 
				}
				if (event.getEventName().equals("CHANNEL_BRIDGE")) {
					// 一个呼叫两个端点之间的桥接事件
					System.err.println("CHANNEL_BRIDGE"); 
				}

				if (event.getEventName().equals("CHANNEL_DESTROY")) {
					// 销毁事件
					System.err.println("CHANNEL_DESTROY"); 
				}

				if (event.getEventName().equals("CHANNEL_HANGUP_COMPLETE")) {
					// 挂机完成事件
					System.err.println("CHANNEL_HANGUP_COMPLETE"); 
				}
			}
			public void backgroundJobResultReceived(EslEvent event) {
				// String uuid = event.getEventHeaders().get("Job-UUID");
				log.info("Background job result received+:" + event.getEventName() + "/" + event.getEventHeaders());// +"/"+JoinString(event.getEventHeaders())+"/"+JoinString(event.getEventBodyLines()));
			}
		});
		client.setEventSubscriptions("plain", "all");
		return client;
	}

	public static void main(String[] args) throws InterruptedException {
		Client client = inBand();
		if (client != null) {
			// 呼叫1002-播放语音
			client.sendSyncApiCommand("originate", "{ignore_early_media=true}user/1002 &playback(text/end.wav)");
			// 呼叫手机-执行lua脚本
			// client.sendSyncApiCommand("originate", "{ignore_early_media=true}sofia/gateway/fs_sg/186xxxxxxxx &lua(welcome.lua)");
			// 建立1002和1000的通话
			// client.sendSyncApiCommand("originate", "user/1002 &bridge(user/1000)");
			client.close();
		}
	}
}

    {ignore_early_media=true}:不设置的话,播放语音文件时会不完整

    playback、bridge等App不懂的去看FreeSWITCH权威指南吧...

    fs_sg:网关,打手机需要配置网关,打内部短号不需要

    welcome.lua脚本功能:播放语音提示并接收用户按键数据保存到MySql话单表中...后续在写...

3:网关配置:

    D:\VS\freeswitch-1.6.19\Win32\Debug\conf\sip_profiles\external目录下新建fs_sg.xml文件,内容配置如下:


  
    
    
    
     
  

4:拨号说明

    软电话拨号:打FreeSWITCH内部用户可以直接打;打手机号需要配置拨号规则从网关打出去,拨号规则配置如下:

        D:\VS\freeswitch-1.6.19\Win32\Debug\conf\dialplan\default下新建fs_di.xml文件(文件名随便),文件内容:


  
    
      
    
  

        软电话打手机号时需要加0来匹配上面这个拨号规则,然后从网关打出去

    Java调用拨号:打FreeSWITCH内部用户可以直接打;打手机号也是从网关打出去,不需要匹配拨号规则
