Voip cost savings, lower bandwidth costs, reduced personnel, less-expensive moves.

According to a latest hour study, VoIP will know a fast rise from 4 percent (the implementation rate that VoIP has today), to 44 percent, by 2008! And these numbers reflect only corporate telephone lines. This great transition will be possible especially due to the reduced cost of equipment

But it all comes down to money: generally, voice-over-IP (VoIP) cost savings fall into three categories: less-expensive moves, (adding and changing - MAC); lower bandwidth costs; and reduced personnel.

A few companies have justified VoIP rollouts entirely on the basis of MAC savings. Others did not embrace this idea because MACs are a part of maintenance contract for an already existing PBX, or because they have employees that do that specific function (they handle MACs of the network).

Accelerator products can help enterprises a lot in addressing the performance requirements of all enterprise applications including VoIP. First, Accelerators change the economics of wide area networking by squeezing an average of 100% - 400% more bandwidth with peaks of 1000% depending on traffic mix. This frees up link bandwidth to support high quality VoIP Services - and it does it without expensive WAN upgrades.

You can determine how much bandwidth to set aside for voice traffic using simple math. However, in a converged voice and data network, you have to make decisions on how much bandwidth to give each service. These decisions are based on careful consideration of your priorities and the available bandwidth you can afford. If you allocate too little bandwidth for voice service, there might be unacceptable quality issues. Another consideration is that voice services are less tolerant to bandwidth depletion than that of Internet traffic. Therefore, bandwidth for voice services and associated signaling must take a priority over that of best-effort Internet traffic. If a network were to use the same prevailing encoding (CODEC) scheme as the current PSTN system, bandwidth requirements for VoIP networks would tend to be larger than that of a circuit-switched voice network of similar capacity.

The major components of a VoIP network are very similar in functionality to that of a circuit-switched network. VoIP networks must perform all of the same tasks that the PSTN does, in addition to performing a gateway function to the existing public network. Although using different technology and approach, some of the same component concepts that make up the PSTN also create VoIP networks. There are three major pieces to a VoIP network.

• Media gateways
  
• Media gateway/signaling controllers
  
• IP network
  

Media Gateways

Media gateways are responsible for call origination, call detection, analog-to-digital conversion of voice, and creation of voice packets (CODEC functions).

World Wide Packets to implement the Mediatrix 0124 VoIP Access Module for Advanced Carrier Class Voice Quality

Sherbrooke, QUEBEC, March 20, 2007 – Mediatrix Telecom, the leader in Voice over Internet Protocol (VoIP) access devices and gateways, and World Wide Packets, a leading provider of Carrier Ethernet solutions, announced today the implementation of the Mediatrix® 0124 VoIP Access Module into the new World Wide Packets LightningEdge® 135B (LE-135B) Ethernet Access Platform.

Company’s momentum—driven by intense customer demand for its products—recently earned Pulver 100 and INTERNET TELEPHONY® Product of the Year honors.

What is actually Internet telephony?

This part is for technical people. It is very nice to know what VoIP can do for you and why you should or should not go your stuff VoIP, but if you want to get deep into the subject, you need to understand some technicalities, which are briefly introduced here.

What is done in a VoIP connection?

To setup a VoIP communication system, we need to have the following things done:
