When VoIP was first conceived it showed promise, giving the ability to provide telephony services over the Internet at low or minimal cost, with speech quality similar to that of conventional telecommunications. While not quite there huge steps have been made since its initial conception, assuming of course your using the right hardware and services for the job.

VoIP places a new demand on Internet capabilities, for the very simple reason that person-to-person speech communication is a real-time activity. VoIP can be a very appealing option that can allow for reduced costs and provide for greater flexibility. In addition to replacing internal voice networks at large corporate offices, VoIP can be used to connect various branch offices through existing WAN links which gives companies an alternative to the PSTN that can continue to grow and be scaled to fit their needs. The publicly accessed Internet however, was not designed originally to support business-grade reliable telecommunications (Ryan, 2013). But it is capable of delivering acceptable quality; it’s just that achieving that quality is often a matter of careful planning. More and more now companies are starting to move from their own leased private lines to relying on the public internet to meet their traffic need which is fine however, there are some issues that companies will be met with when relying on such a medium for their networks. (Wikipedia , 2013)

One of the main issues that could arise would be the installation of the equipment, as traffic volumes increases, there are always going to be issues with reliability and availability creating a growing need for routing diversity. Any company with a public or private connection is going to need to make sure that their current network equipment is going to be sufficient. Even the shortest delay can cause your sound connection to break up. QoS is one of the major issues in VOIP...
