While working for ICS Ltd, I planned and implemented a remote working solution for employees to work from home and still take calls/messages to pass on to clients.
For this I utilized Draytek routers, NEC VoIP phones, and Axel thin clients, combining all of this with the power of virtualization.
I was able to create virtual machines for the Thin Clients to connect back in to, plus the virtualization platform allowed for other services to be migrated to it reducing the server foot print and saving energy.
