In the mobile app, users are able to see and access Paging Group Contacts under the Other tab. You can then click Page announcement and make a page. There is also an option to "Add to quick contacts". This works and shows up on both the mobile app and the desktop app, however you are unable to use the Contact in the desktop app. There is no way to easily create a simple way to page. The only way is to know *84XXX# where XXX is the extension number (can be longer than three digits). This is very clunky and reminds me of something from the 80's or 90's, not a "cutting edge" phone system.
