Voice Over Internet Protocol or 'VoIP' as it is referred to in the telecommunications industry was originally used in the United States to transport telephony traffic. Using the efficiency of the Internet to deliver information made it very cost effective and therefore cheap for the end user.
Initial quality and performance problems due to lack of service parameters have now been overcome.
BT's multimedia service provides quality of service by using controlled IP transport networks, and by advising customers on the best ways to deliver quality on their own networks. This includes voice calls to existing telephony products such as a standard BT line, or an advanced voice service such as BT's Featurenet.
Given the falling price of bandwidth, and increased demand for customer intranets and broadband access, the opportunity for converged voice and data services has now become a reality.
