I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The web site part on your screen is just a form.  The software on the web server connects to their phone system to call you.  It's probably custom software.  PBXs that run on PCs are available so it may not be all that difficult.  Telemarketers use computers to dial out all the time.  If you search for "computer dialing" you'll find quite a few programs to dial out from your computer.
