MY CODE
import javax.telephony.*;
public class InCommingCall {
public InCommingCall() {
* Create a provider by first obtaining the default implementation of
* JTAPI and then the default provider of that implementation.
Provider myprovider = null;
try {
//JtapiPeer peer = JtapiPeerFactory.getJtapiPeer(null);
JtapiPeer peer = JtapiPeerFactory.getJtapiPeer("net.xtapi.XJtapiPeer");
myprovider = peer.getProvider(null);
catch (Exception excp) {
System.out.println("Can't get Provider: " + excp.toString());
excp.printStackTrace();
* Locate the Terminal associated with our near end and place a call
* observer on it. This will instruct the implementation to add a call
* observer once a telephone call comes to the Terminal. We are assuming
* Terminals are named after a primary telephone number on that terminal.
Terminal terminal;
try {
Terminal[] T=myprovider.getTerminals();
for(int i=0;i<T.length;i++){
System.out.println(T.getName());
terminal = myprovider.getTerminal("0");
terminal.addCallObserver(new CallAndDTMFObserver());
System.out.println("Now standing by for phone calls");
catch (Exception excp) {
excp.printStackTrace();
public static void main(String argv[]) {
InCommingCall callReceiver = new InCommingCall();
}
