70207_C000.indd viii 11/13/2008 5:01:46 PM Preface Voice over Internet Protocol (VoIP) is emerging as an alternative to regular public telephones IP telephone service providers are moving quickly from low-scale toll bypassing deployments to large-scale competitive carrier deployments This is giving enterprise networks the opportunity and choice of supporting a less expensive single network solution rather than multiple separate networks Voice deployment over packet networks has experienced tremendous growth over the last four years The number of worldwide VoIP customers reached 38 million at the end of 2006 and it is projected that there will be approximately 250 million by the end of 2011 VoIP is a reality nowadays and each day, more and more individuals use this system to phone around the world There are many common programs that make it easy to use VoIP such as Skype, MSN Messenger, VoIPcheap, and so on The evolution of the voice service to VoIP from the circuit-switched voice is due to the proliferation of IP networks that can deliver data bits cost-effectively VoIP technology has been attracting more and more attention and interest from the industry VoIP applications such as IP telephony systems involve sending voice transmissions as data packets over private or public IP networks as well as reassembling and decoding at the receiving end Broadband-based residential customers are also switching to IP telephony due to its convenience and cost-effectiveness The VoIP architecture pushes intelligence towards the end devices (i.e., PCs, IP phones etc.), giving an opportunity to create many new services that cannot be envisaged using the traditional telephone system Recently, there has been an increasing interest in using cellular networks for real-time packet-switched services such as VoIP The reason behind this increased interest in VoIP is to with using VoIP in All-IP networks instead of using circuit-switched speech This would result in cost savings for operators as the circuit-switched part of the core network would not be needed anymore Similar to the wireline networks, voice in wireless mobile networks started with the circuit-switched networks Since the first deployment of the commercial wireless systems, wireless mobile networks have evolved from the first generation analog networks to the second generation digital networks Along with the rapid growth of the wireless voice service, the third generation wireless mobile networks have been deployed offering more efficient circuit-switched services that utilize many advanced techniques to more than double the spectral efficiency of the second generation systems 70207_C000.indd ix 11/13/2008 5:01:46 PM .. .VoIP HANDBOOK Applications, Technologies, Reliability, and Security
