In the modern age, it is fairly commonplace to see people having meetings through video messaging applications. Programs such as Google Hangouts, Skype and Facebook Messaging offer this alongside generic text messaging. I will explain how to start a conversation like this using the Facebook app. For instance, two people from a small business are on holiday but are required to participate in a weekly meeting, they will need to know how to set this up.
The screenshot below shows me having an interaction via Facebook Messenger with my classmates.
To start, the user must select who they want to do the video conversation with, This can be accomplished by pressing the small camera logo on the right hand side of the chat box. Depending on whether the other person is online or not (green light means yes) you will get a response pretty promptly.
