I need you to program a calling backend application similar to [url removed, login to view] and [url removed, login to view] Please see the attached PDF document for more details.
1. An user inputs a phone number (or a list of numbers)
2. Types in a TextToSpeech message or Record Voice using microphone
3. Sets the calling time
4. Server automatically dials the number at the pre-set time and plays the TextToSpeech message or user-record voice file
I'd prefer modification on existing applications so that the overall development cost will be lower.
