Product Context (5 minutes)

WhatsApp Calls is a voice and video calling feature integrated into the WhatsApp messaging app. It allows users to make free calls to other WhatsApp users over an internet connection. Key stakeholders include:

1. Users: Seeking free, convenient communication
2. WhatsApp/Meta: Aiming to increase user engagement and retention
3. Telecom providers: Potentially seeing reduced traditional call revenue
4. Advertisers: Interested in user engagement data

User flow:

1. Open WhatsApp and select a contact
2. Tap the call icon to initiate a voice or video call
3. Wait for the recipient to answer
4. Engage in the call
5. End the call and optionally rate the call quality

WhatsApp Calls fits into Meta's broader strategy of creating a comprehensive communication ecosystem, competing with traditional telecom services and other messaging apps like Telegram or Signal. The feature is in the growth stage of its lifecycle, with ongoing improvements in quality and feature set.

Software-specific context:
