I've used the Megacall software since 2013 and it's worked flawlessly for us. It's a great tool for generating phone calls from website visitors. It's very user friendly. You can set many variables for each caller such as the number they will dial and how long the call should last. It has multiple options for each call so you can customize your calls for each visitor. We even use it to generate text messages. If you're looking for a robust solution for automated telephone follow up, this is definitely the software to use. I am constantly amazed at how responsive the developers are and the amount of flexibility available to make this system work exactly the way we need it to.
