SSI Fellows Yo Yehudi and Malvika Sharan, along with Kaitlin Stack Whitney have produced guidance on 'Enhancing the Inclusivity and Accessibility of Your Online Calls'.

From the abstract:

Multinational video conferencing and online calls for training and community building have been commonplace for many organisations, even prior to the COVID-19 pandemic. These calls can be intended to be hands-on and interactive, but it requires conscious designing, pre-planning, and careful moderation in order to make them inclusive for a range of abilities.

This article describes formats and tools for designing online training calls for accessibility... These measures will aid participation for a broad audience but may be especially helpful for people who are deaf or hard of hearing, people for whom the call language isn’t their preferred language, and people who are not comfortable speaking in front of a group.
