Question

I want to develop a system that users remotely interact with over a phone call. Like your bank’s phone banking system.

This system will be very simple: when a user calls, it merely needs to prompt the user and accept input purely through the keypad. Additionally it will need to be able to receive and send text messages.

1- Are there non-proprietary frameworks out there that support this?

2- Can anyone share the basics of their experiences in deploying this kind of system? Pitfalls, what to watch out for, etc?

Answer 1

There is an opensource project Asterisk that will help you accomplishing this.
