+# Beta Test Plan
+
+## Core Features
+
+### Icing protocol
+- Handshakes
+- ECDH
+- Compression
+- Audio error correction
+- In-call pubkey share
+- Trust shifts
+
+### Icing dialer (based on Icing kotlin library, an Icing protocol implementation)
+- Call
+    - Encrypted if public key available
+    - Allows users to share their public keys
+    - Normal call if conditions unment
+    - Encrypted and clear DTMF transmission
+    - SIM choice on call
+    - Call history
+
+- Contacts
+    - Contact creation / editing
+    - Contact sharing via QR code / VCF
+    - Contact search
+    - Favorite contacts
+    - Storage of user public keys
+    - Blocked number
+    - Contact preview (picture, number, public key...)
+
+- Visual voicemail
+    - Play / Pause
+    - Notification
+    - Quick link to call, text, block, share number...
+
+- SIM settings
+    - Default SIM choice
+
+- Asymetric Keys
+    - Secure storage
+    - Generation at startup if missing
+    - Full key management
+    - Secure generation
+    - Exportation on creation (insecure generation)
+    - Importation
+    - Trust shift
+
+
+## Beta Testing Scenarios
+- Clear call from Icing dialer to another dialer (Google, Apple...)
+- Clear call from Icing dialer to another Icing dialer
+- Clear call from Icing dialer to an icing pubkey-known contact but without Icing dialer
+- Encrypted call from Icing dialer to a known contact with Icing dialer
+- Encrypted call from Icing dialer to an unknown contact with Icing dialer
+- Create / Edit / Save contact with(out) public key
+- Share contact as QR code / Vcard
+- Import contact from QR code / Vcard
+- Listen to voicemail
+- Record encrypted call and check the encryption
+- Change default SIM
+
+## User Journeys
+
+Mathilda, 34 years-old, connects to her PayPal account from a new device.
+To authenticate herself, PayPal sends her a code on her voicemail.
+Mathilda being aware of the risks of this technology, she has set up strong Icing authentication with her network provider by registering a pair of her Icing public keys.
+When she calls her voicemail, Icing protocol is triggered and checks for her key authentication ;
+it will fail if the caller does not pocesses the required Icing keys.
+Mathilda is thus the only one granted access, and she can retreive her PayPal code securely.
+
+Jeff, 70 years-old, calls his bank after he had a problem on his bank app.
+The remote bank advisor asks him to authenticate, making him type his password on the phone dialer.
+By using the Icing protocol, not only would Jeff and the bank be assured that the informations are transmitted safely,
+but also that the call is coming from Jeff's phone and not an impersonator.
+
+Elise is a 42 years-old extreme reporter.
+After interviewing Ukrainian opposition's leader, the SBU (ex KGB) are looking for her accross the whole country.
+She hides in western moutains near Romania, and she barely receive cellular network.
+She suspects her phone line to be monitored, so the best she can do to call for extraction safely, is to use her Icing dialer.
+
+Paul, a 22 years-old developer working for a big company, decides to go to China for vacations.
+But everything goes wrong! The company's product he works on, is failling in the middle of the day and no one is
+qualified to fix it. Paul doesn't have WiFi and his phone plan only covers voice calls in China.
+With Icing dialer, he can call his collegues and help fix the
+problem, safe from potential Chinese spies.
+
+## Evaluation Criteria
+- Can a private key be generated
+- Can a normal call be made?
+- Can an encrypted call be made?
+- Can a contact be created / edited / imported / exported?
+- Can a voicemail be listened to?
+- Is the encryption fast enough, light enough to be usable (audible call)
+- Is the encryption strong enough not to be deciphered by a modern (as of 2025)
+  supercomputer?
