Run the app, start the service, and forget about it until you reboot. It listens for calls to be made or answered and just brings up a screen over your dialer. Access the call from the notification bar. When you need to dial numbers for automated phone systems you will have to manual go to it and come back to the screen, but hey this is better than purchasing a whole new phone! I attached the .apk since I can't post links as a new user.
I hope this helps someone out! Thanks guys! Let me know if you run into any issues.
