Bandwidth

One of the greatest challenges of VoIP is voice quality, and one of the keys to improving voice quality to an acceptable level is bandwidth. Therefore, additional bandwidth is certainly needed, if only to support additional traffic as demand for VoIP continues to grow. While additional bandwidth is a necessity for a network that is required to support voice in addition to the data traffic that is might have carried all along, additional bandwidth is not, by itself, a complete solution for the QoS issue.PrioritizationOnce sufficient bandwidth is available to enable high-quality voice transfer, we need to control and prioritize access to the available bandwidth. As this regulation is not exerted over the Internet presently and because the IP is designed completely for the transfer of the data from its outset, depending upon the usage of the bandwidth, voice quality over the Internet might vary from acceptable to atrocious.
