Amazon is launching group video and audio calls for Echo devices in Canada.
Group video calls allow up to seven people to join an audio or video call on compatible Echo devices, including the Echo Show, Echo Dot, and Echo (2020). Also, Amazon says that you can create and name these groups in the Alexa app.
It's also worth noting that these video and audio calls support Alexa commands such as "Alexa, call my family" to contact a specific group you've created.
Amid the ongoing COVID-19 pandemic, it appears that Echo group calls could work as a decent alternative to video chat services like Zoom and Google Meet, especially since there is no limit on call times. That said, you obviously need an Echo device for group calling to work.
