- WhatsApp launched Guest Calling, enabling non-users to join audio and video calls without an account or the app.
- Calls include end-to-end encryption, have no time limits, and feature waiting room controls for hosts.
- The update positions the messaging platform as a direct competitor to Zoom and Google Meet.
Meta is ramping up its competition against established video conferencing platforms by rolling out a new Guest Calling feature for WhatsApp. The update allows users to invite anyone to one-on-one and group calls, even if the invitee does not have an account or the native client installed.
How Browser-Based Guest Calling Works
Participants without an account can join directly from a desktop browser using a shared invite link. This capability builds upon Meta’s earlier rollout of native voice and video call support on the web client.
To prevent disruption and maintain digital safety, hosts maintain strict control over each session:
- Waiting room: External guests cannot enter immediately; they are placed in a waiting queue until the host manually approves their entry.
- Host controls: Organizers can remove any guest participant at any point during the session.
- Privacy barriers: Guests are restricted from viewing participants’ phone numbers, sending private direct messages, or initiating direct calls.
Collaboration Features and Security
Even without an active profile, guests gain access to essential collaboration tools. During an active call, they can share their desktop screen, send real-time emoji reactions, and use the virtual hand-raise feature.
| Feature | Guest Participant | Registered WhatsApp User |
|---|---|---|
| Account Requirement | None | Mandatory |
| End-to-End Encryption | Yes | Yes |
| Time Limits | No limit | No limit |
| Screen Sharing & Reactions | Supported | Supported |
| Visibility of Phone Numbers | Hidden | Subject to group settings |
Challenging Zoom and Future Integrations
By pairing unrestricted call duration with robust end-to-end encryption, WhatsApp eliminates the primary friction points of free-tier services like Zoom and Google Meet. Looking ahead, Meta is also developing calendar integrations scheduled for release later this year to streamline corporate and personal scheduling.
Organizing spontaneous interviews, customer calls, or cross-platform catchups no longer requires forcing participants to download software or register phone numbers. A simple browser link provides a private, encrypted meeting room with no arbitrary 40-minute disconnects.
No time limits combined with end-to-end encryption makes this a massive shift for quick client meetings. How will WhatsApp handle bandwidth stability compared to dedicated enterprise tools? Also curious if anyone knows whether host permissions can be transferred mid-call.
