Can You Attend a Video Call on Messenger from Two Different Devices Using the Same Account?

Yes, it is indeed possible to attend a video call on Messenger from two different devices using the same account. When you initiate or join a video call on one device, you can log into the same Messenger account on another device and join the call as well. However, it's important to note that this might create audio feedback issues if both devices have their speakers on. It is generally recommended to mute one of the devices to avoid any echo or noise.

The Straightforward No

While Facebook allows its users to make multiple logins using the same account credentials and automatically mirror activity on one device to the other, it doesn't allow you to attend calls from two different devices using the same account. Whenever you receive an incoming Messenger call, it will be seen on both devices you're logged into, but you can only attend calls from one device—the one from which you receive the call first. The same rule applies to making calls. Even if you're already in a video call on one device, you can make a call from another device, but as soon as you click the video icon, the ongoing calls from the other device will be disconnected and connected to the device on which you made the call.

Cross-Device Messaging

It is worth noting that you can use Messenger on different devices with the same account for messaging. However, you can't attend video or voice calls simultaneously from these different devices. Facebook doesn’t allocate two server streams for a single account, making simultaneous video calls across devices a practical limitation.

The Technical Feasibility and Enterprise Solutions

Technically, there is an opportunity to attend one video call from different devices simultaneously, but none of the consumer messengers provide this option for users. The Dialog Messenger protocol supports this feature and can optionally provide it for enterprise app users. This means that while it is not currently supported by consumer Messenger, it could be an option in future enterprise applications.

User Experience and Notifications

When you are already in a video call and logged into two different devices, if someone tries to call you, their call will be automatically disconnected, and you'll see a message on the screen that your "Device is Busy." If you try to make a call from another device, you will see the video or voice calling icon disabled, preventing you from making the call.

So, while the technical limitations currently restrict simultaneous video calls, understanding these restrictions can help you make more informed decisions about your calls and ensure a smoother user experience.
