A reliable communication service suitable for all types of projects are needed. Trucks, escalators, crane and lift personnel need to communicate in different groups and at the same time management and planning needs to be able to get hold of resources. 

A dispatcher typically distribute work orders to vehicles and mobile workers in text form (in apps, SMS or e-mail) to smartphones or PDAs. However, for a mobile worker on the run, “voice” is still the safest, quickest and often best way to communicate back to the dispatcher or within a group. The possibility of reaching the fleet of vehicles in groups or individually is important in many situations.
