Avoid the jitters by ensuring networks are fully prepared for VoIP implementation

摘要

Many IT directors have reservations about using voice over Internet Protocol (VoIP), believing the network will not be of a high enough quality to carry both voice and data traffic satisfactorily. But there is no need to get the jitters about implementing VoIP -"jitter" (the variable arrival of network packets) is just one of the quality degradations you might expect from using a data network for voice. There are a number of ways companies can prepare their networks to be of the right technical quality and reliability to ensure high-quality voice transmission. A whole array of technologies and tools are available to make sure the network maintains its quality of service (QpS): a predefined level of performance in a data communications system. QpS can prevent jitters, round trip delay and can also prevent packets being lost.
