WhatsApp network forensics: Decrypting and understanding the WhatsApp
call signaling messages

we were able to acquire the following artifacts from the network traffic:
* WhatsApp phone numbers.
* WhatsApp phone call establishment metadata and datetime stamps.
* WhatsApp phone call termination metadata and datetime stamps.
* WhatsApp phone call duration metadata and datetime stamps.
