Walkie Talkie enterprise system which we have been built for a US communication company, the system allows the owner company to use it as embedded kiosk system in their own walkie talkie hardware devices, the system allows users to talk to each other (Walkie Talkie Style) in secured VOIP channels created and managed by the system.

And the whole system is controlled via the Admin Control Panel for managing devices, channels, data consumption, settings, kiosk mode, statistics, etc.
 

One of the biggest challenges that I have been faced was that the company has been set a restriction of 100MB data consumption for each device per month, so its was very hard to keep the data consumption as low as this limit beside keeping the sound quality the same, and to reach this we did a lot of optimizations on the app structure and the way the data transfer to reach this limit so it was  a very hard challenge, but at the end I succeed to get over this issue and controlling the app data consumption to be as the target limit

The system includes two main parts
 

Client App

- Device setup and pairing via authentic credential login method or via secured QR-Code Authentication method for easy and fast setup

- Control the device as Admin Owner to force the profile rules, allowed permissions, and system parts which the user can access

- Full kiosk mode implementation to isolate the device and force the client app as the main home app to prevent any access to any part of the device’s OS

- Display and managing all the channels which the user is member of it

- Advanced walkie talkie style channel page which allows the user to talk/listen to others in the same channel

- Controlling and detecting the device PTT (Push To Talk) hardware button events to allow walkie talkie style and talking while the screen is off

- Secured method to allow the admin to enable/disable kiosk mode remotely

- Calculating data consumption and force the maximum usage of the plan which the user is part of it

- Secured internal settings which are accessed by the admin only by the physical access of the device for configuration and debugging

- Internal messages communication system to allow users to communicate with the administration.
