Android Question App for standalone AnsweringMachine

[Gnappo jr]

I ask for your opinion on the feasibility of an app that resembles a voice mail in our smartphone.
is it possible to make an app that after a certain number of rings repeats with a recorded message and registers the voice of the interlocutor?
Is there any excuse for accessing the audio part during the phone call?
Thank you all

There is an hardware problem: the speaker is not connectible with the microphone. So what you play cannot clearly be heard by the third party.

is there any other way to insert a pre-recorded stream in telephone communication?
