Hello, I am looking for someone to write an article on Voice over IP. It needs to be at least 2000 words. Internet telephony has gained much popularity as an easy way to communicate and make a call to distant places via the internet. It provides a feature of free telephone calls to be made with their software anywhere in the world. These internet telephony products are sometimes called VOIP products. Like e-mail spam, voice spam (also called SPIT-Spam over Internet Telephony) is a common misuse of VOIP products and services that transfer bulk messages to phones via the internet and broadcasted through VOIP.
