我有一个 Java 程序，它发起对客户端的调用，并在应答后将其连接到拨号方案中的分机。该扩展反过来运行 AGI 脚本来与客户端进行一些交互。如果客户坚持到最后，一切都是完美的。但如果他在中间挂断，AGI 脚本会继续运行。我希望它在客户端挂断时停止。
以下是原始 java 程序的摘录：
OriginateAction originateAction;
ManagerResponse originateResponse;
originateAction=new OriginateAction();
originateAction.setChannel(phoneNumber);
originateAction.setExten("700");
originateAction.setContext("users");
originateAction.setPriority(new Integer(1));
//connect to Asterisk and login
ManagerConnectionFactory factory = new ManagerConnectionFactory("localhost","******","******");
managerConnection = factory.createManagerConnection();
managerConnection.login();
//send the originate action and wait for a maximum of 30 seconds to get a response
originateResponse=managerConnection.sendAction(originateAction, 30000);
拨号方案的摘录
exten =>700,1,Agi(agi://localhost/message.agi,${var1},${var2},${var3},${var4}); script to play
以及 agi 脚本的摘录
public void service(AgiRequest arg0, AgiChannel arg1) throws AgiException {
setVariable("missedSteps","4");
verbose(" -------------- missed steps: 4 ----------------", 3);
// Answer the channel and welcome
answer();
streamFile("silence/1");
streamFile("welcome");
setVariable("missedSteps","3");
verbose(" -------------- missed steps: 3 ----------------", 3);
//Read the file
streamFile(fileName);
setVariable("missedSteps","2");
verbose(" -------------- missed steps: 2 ----------------", 3);
..........
..........
setVariable("missedSteps","1");
verbose(" -------------- missed steps: 1 ----------------", 3);
..........
..........
setVariable("missedSteps","0");
verbose(" -------------- missed steps: 0 ----------------", 3);
//hangup
hangup();
如您所见，我试图保留一个跟踪脚本内演变的变量，并且我想保留该变量以将其存储在调用日志中。如您所见，我添加了一些用于调试的详细命令，而我在控制台上看到的是，无论客户端是否挂断，“missedSteps”变量都会从 4 变为 0。
