I would request you to add a feature which allows the user to play a audio or video file (instead of sending sms) to a phone number.
For example: When I have a missed call or when an incoming call (and i am busy) is from a family friend I would like to do
1. Pick Up
2. Play a audio file(s) (this is a pre-recorded file in a local language) or a video file(s) (if video call is supported)
3. Hang Up
This way I can have personal messages

in local language for individual contacts.
NOTE: When playing the audio or video file the phone speaker or mic should not be enabled else it's not that interesting.
Or is there already a way to do this ? If yes, I will be happy if you can tell me what steps
thanks in advance
