Just wanted to share something that has helped us out tremendously. Zello Walkie Talkie app (free) www.zello.com Android, iOS and even PC for dispatch.
Very similar to the old Nextel system. You can talk one to one or one to many. Hope this helps some of you guys out. If you want a demo. Look me up, KJ7ON (yeah I am an amateur radio nerd as well) -Jon Off-Grid Networks
