Upgrading the Next-generation Network Part I
A Signaling Perspective
There is no denying the excitement and momentum generated by Voice over Internet Protocol (VoIP) services. Although it is considered to be a disruptive technology, VoIP offers many outstanding attributes such as integration with web-based applications, simplicity in call routing and enhanced voice services.
In a relatively short time period, VoIP has gained strong acceptance as an overlay or even a replacement to existing TDM technologies in both operator and enterprise telecommunications networks. The popularity of VoIP is evident in a recent report published by a leading industry analyst firm, which indicates the number of VoIP subscribers will more than double over the next two years. This trend is being seen in all regions of the world.
