You may not know this but your GSuite subscription includes a very powerful virtual meeting technology called Hangouts Meet. It is similar to other services you may have used like GoTo Meeting and Zoom. Like those services, you can hold a video meeting or have participants call in using a phone number and PIN. Unlike those services, no third-party software or plug-ins are required to join a meeting using a browser such as Chrome, Firefox, Safari or Edge. The meeting happens entirely in the browser and leaves no software behind. If joining a meeting from a mobile device you will need to install the app, unless you are simply dialing in with a phone number and PIN.
I would be happy to meet with you to discuss how to integrate Google Hangouts Chat into your current workflow. Please open a ticket to request an appointment.
