The reason for the prevalence of VoIP is that it gives significant benefits compared to legacy phone systems. The key benefits are as follows:
Cost savings. The most attractive feature of VoIP is its cost-saving potential. When we move away from public switched telephone networks, long-distance phone calls become inexpensive. Instead of being processed across conventional commercial telecommunications line configurations, voice traffic travels on the Internet or over private data network lines.
For the enterprise, VoIP reduces cost for equipment, lines, manpower, and maintenance. All of an organization’s voice and data traffic is integrated into one physical network, bypassing the need for separate PBX tie lines. Although there is a significant initial setup cost, significant net savings can result from managing only one network and not needing to sustain a legacy telephony system in an increasingly digital and data-centered world. Also, the network administrator’s burden may be lessened as they can now focus on a single network. There is no longer a need for several teams to manage a data network and another to manage a voice network. For consumers, VoIP reduces the charge of subscription or usage, especially for long distance and international calls.
