Certainly! Here's a basic example of a FreeSWITCH Java demo application that can make a phone call:
```java
import org.freeswitch.esl.client.OutboundClient;
import org.freeswitch.esl.client.transport.event.EslEvent;
import org.freeswitch.esl.client.transport.message.EslMessage;
public class FreeSwitchJavaDemo {
public static void main(String[] args) {
String host = "localhost";
int port = 8021;
String password = "ClueCon";
try (OutboundClient client = new OutboundClient()) {
client.connect(host, port, password);
String destinationNumber = "1000";
String callerIdNumber = "1234";
EslMessage response = client.sendSyncApiCommand(
String.format("originate {origination_caller_id_number=%s}sofia/gateway/mygateway/%s &echo", callerIdNumber, destinationNumber)
);
if (response.getHeaderValue("Reply-Text").startsWith("+OK")) {
System.out.println("Call successfully placed!");
} else {
System.out.println("Failed to place the call!");
}
// Listen for events
client.addEventListener((EslEvent event) -> {
// Handle and process events here
});
// Wait for some time to receive events
Thread.sleep(5000);
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
```
In this example, we use the FreeSWITCH ESL (Event Socket Library) Java API to establish a connection with the FreeSWITCH server. We then use the `sendSyncApiCommand` method to send an originate command, which initiates a call from `callerIdNumber` to `destinationNumber`. We also add the `&echo` parameter to have an echo application handle the call.
After sending the command, we check the response to see if the call was successfully placed. Additionally, we can add an event listener to handle and process events received from FreeSWITCH.
Remember to replace `localhost`, `8021`, `ClueCon`, `1000`, and `1234` with your own FreeSWITCH server details, gateway, and desired phone numbers.
This is just a basic example to get you started. You can explore the FreeSWITCH Java API documentation and sample applications for more advanced functionality and customization options.
