Hi Guys My Name is Daniel Di Fabrizio i am one of the architects behind " Tossy Dispatch Cloud Sys".
Tossy "Desk" is designed in VB over .NET in windows forms.
This project is about to create a ptt app.Push-to-talk application for smartphones (android) and PCs.(similar to zello or voxer)
The idea is to integrate a Walkie talkie (seamless) functionality to our Dispatch android app for drivers.
A button for push-to-talk. The scenario will be "talk group" or one on one, Like a Two way radio.
The dispatcher console run over the web and the drivers android devices as a main communication frame for both parts.
Every channel is suppose to handle approx. 200/250 users.
Use with Wi-Fi or mobile data.
The app is simple and don't have to have any fancy features, just plain communication between two parts.
