Abstract

One of the highest demand applications is the transmission of voice over IP networks with a high level quality of service and efficient bandwidth use. This paper shows some recommendations and protocols that lead to convergence communications networks for voice and data transmission over of the same structure. We focus on International Telecommunication Union Recommendation H.323 for voice over IP, which uses IP/UDP/RTP encapsulation for audio. Some metrics that make possible the IP telephony are also analyzed and H.323 architecture is presented for this technology. The main aspects of the problematic of voice and data transmission are analyzed.
