I am not sure if this is the place I should be looking for my business requirement so any leads will be great.
I want to setup a phone system, which users call and enter a 3-4 digit number and hang up. The system upon receiving the call and the code sends this info to a web-based application with the calling phone number and the code.
Can you please let me know what do I need to implement this solution?
Thanks a lot for your help
