Need a VoIP expert

Dear Sir or Madam,

I am searching for an expert in VoIP and Asterisk or alternative program.

What ist he problem/task?

I am going to create an android app like „Marcophono“, which you can find in the german playstore.

With this app Users can do prank calls.

It works like this:

1)User A choose a scenario in the App.

2)In this scenario User A can see different Audio Messages.

3)User A calls User B with the App.

4)If user B answer the call, User A can press different buttons in the App like „Hello my friend“, „How are you“ etc. User B hear that messages directly live, but not the voice from User A. Important: User B did not have this app installed on his phone.

Thats the point I need your experience. I think the owner of „Marcophono“ did this with VoIP.

But I am not sure about this. I need someone who can develop the VoIP part.

Kĩ năng: VoIP, Asterisk PBX, FreeSwitch
