A phone receives either direct calls, or diverted calls from different mobile or landline numbers.
This Proof of Concept app logs incoming calls with the full available caller information app including if a call was diverted, which number it was diverted from and the number of the caller.
This Proof of Concept app will then be installed on android phones and used to test the correct caller information in differenct networks within europe.
No styling is required. It is a Proof of Concept piece to later be included in a larger app.
