      How does it work?

      Your customers are more likely to answer from an area code they live in. This gives your customers the sense is local and meant from them. Below you can simulate a campaign from three US cities demonstrating this concept.

      Enter Your Number

      The demo below will simulate calling you as if you lived in three major metropolitan areas.

      Confirm Your Cities

      You will be called from Chicago, San Francisco, Dallas, or a sequence of all three. When customized this will work with any region or country.

      Answer Your Phone

      Answer your phone to hear confirmation of where the call is coming from.

      The Code

      The following Tropo Scripting code uses Java in order to power the outbound dialer functionality. The main portions of this app involve masking caller ID and checking call status.

      Take the tutorial
      package com.tropo.demo;
      import static com.voxeo.tropo.Key.FROM;
      // Rest of imports
      public class CallServlet extends HttpServlet {
          private static final String TO = "Number to Dial";
          private static final String FROM = "Caller Id";
          private static final String TOKEN = "Your Tropo App Token";
          private static final String MESSAGE = "This is a message";
          protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
              System.out.println("Starting call session");
              Tropo tropo = new Tropo();
              TropoLaunchResult result = tropo.launchSession(TOKEN);
          protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
              Tropo tropo = new Tropo();
              try {
        , FROM(FROM));
              } catch (TropoException te) {
