Profession: Engineer/Designer

Inspired by: In my community i noticed that many institutions and companies face the problem of internal communication at times they communicate through the air by shouting in loud tones across offices. so i decided to fine a solution. This device does real time voice calls, SMS and file transfers. it is also very easy to use and very economical to install since it uses the existing office network equipment. Traditional IP and Fixed phones for office use are very very expensive for a medium size or small business to purchase the SERIAL IP PHONE that i have developed will be a remedy.
