Creating a Who's Who or Contact List in SharePoint Online

Dear All

I would like to create a page in SharePoint which shows the photograph, name, job title and telephone extension of all our employees. This could be a SharePoint list or library. 

The individual photos, names, job titles and extensions are already visible for individuals when you go to 

https://mysharepointurl-my.sharepoint.com/PersonImmersive.aspx. For example, I can see my own photo, name and details. 

Please could you help me understand how I could pull this information together for all our users and make it accessible for people to view, sort and filter?

Many thanks

Daniel
