the code is:
new_session = new Session();

new_session.originate(session, "sofia/default/1001@192.168.1.2");

new_session = new Session(session, "sofia/default/1001@192.168.1.2");

// wait for it ... answer
new_session.waitForAnswer(10000);

// IF everybody is ready, then bridge our current session & the new_session
if (session.ready() && new_session.ready()) {
    bridge(session, new_session);
}

// log to the console
console_log("***********Voila!\n");

// hangup when done
new_session.hangup();


Is there anything i have to add to the program or any other requirements are needed to run this javascript successfully?
please assist me to do this.
