Web Conferencing

Western has two centrally funded and supported web conferencing systems. These systems allow for video and/or audio conferencing and include other collaboration features which can be used in a variety of administrative and academic use cases, including meetings and live classroom environments.

The two systems are Microsoft Teams and Zoom. While generally they each have the same core functionality (i.e. they facilitate web conferencing sessions), they each have different feature sets and constraints which should be considered when deciding which system to use for any particular context.

In order to help you make an informed choice on which tool to use for your specific use case, in the section below we have provided an overview and feature comparison of the two systems.

For large, broadcast-type events (i.e. most participants are only viewing) where not as much interaction is necessary or desired, Zoom Webinars and Microsoft Teams Live Events are available. See Webinar Tools for a comparison of those two options.

If you require further information or assistance with access and/or using the systems, please contact WTS by creating a Service Desk ticket at https://westernu.atlassian.net/servicedesk.

Concurrent Meeting (Plus) allows users to simultaneously host 20 meetings and is available upon request to the WTS Helpdesk at an additional cost. Note that the host can only attend one session at a time. See Zoom Concurrent Meetings for more infromation.
