I utilize two programs called Skype and Zoom, that you will need to download. Skype/Zoom is very easy to download and use, and allows people to call each other’s computer You can download or learn more about Skype/Zoom directly at skype.com and zoom.com for Windows, Mac and Linux.2. Like anything, the faster the internet, the better -DSL or Cable are optimal https://support.skype.com/en/faq/FA12413/how-do-i-create-a-skype-account
