VoIP stands for Voice over Internet Protocol and implies making use of telephone services through and over Internet. It means that if you have a broadband connection, you can get phone services through internet.
VoIP technology has become very significant these days. Though it has some commonality with the conventional telephone system, however, it offers some added advantages too. It facilitates domestic, local, long distance and international calls and all these at considerably low rates. VoIP technology is consistently progressing with new features and additional benefits.

As with most real-time services, VoIP demands that the network provide predictable performance within a constrained boundary of transport parameters. This section surveys the key networking issues that an organization or service provider must carefully consider when deploying a VoIP solution.
Latency (also referred to as delay) is the time that it takes a packet to make its way through the network to the terminating device. In other words, latency is the time it takes the speaker’s voice to reach the listener’s ear. While large latency values do not necessarily degrade the sound quality of a phone call, they can disrupt the rhythm of conversation, making it difficult to interact.
Several factors contribute to latency in a multiservice network, including:
• The time it takes for the endpoints to create the packets used in voice services, known as packet creation latency
• The time it takes to serialize the digital data onto the physical links of the interconnecting equipment Read more…
