I wanna get the project for auto cancel call with scheduled time. If you have the experience, you can make easy. For example: For incoming calls, if your status is busy, you should let the call ring twice and automatically cancel the call. After that, you need to send a predefined SMS.....The status of the caller is either auto assumed through the meetings set in google calendar and outlook, or the user should be able to manually set as busy also. My total budget is $100 for this project.
