this is from another forum, but shows use of an app called Zello for smart phones being used to coordinate rescue efforts in Beaumont and other remote locations... if anyone can add to how this app works please do so, I'm a technology luddite... I don't have a smart phone but a Kyocera flip phone with a dedicated function button and would like to know if this will work on my phone... thank you
