Note: In general phone service via VOIP costs less than equivalent service from traditional sources. This is largely a function of traditional phone services either being monopolies or government entities. There are also some cost savings due to using a single network to carry voice and data. This is especially true when users have existing under-utilized network capacity that they can use for VOIP without any additional costs. In the most extreme case, users see VOIP phone calls (even international) as FREE. While there is a cost for their Internet service, using VOIP over this service may not involve any extra charges, so the users view the calls as free. There are a number of services that have sprung up to facilitate this type of “free” VOIP call. Examples are: Free World Dialup and Skype for a more complete list see: VOIP Service Providers
Traditional telephony applications, such as outbound call center applications and inbound IVR applications, normally can be run on VOIP.
There are a number of VoIP phone systems available on the market including, one example being 3CX which is a software-based VoIP PBX for Windows, Linux and the cloud. For a comprehensive list of solutions visit VoIP PBX and Servers.
VOIP makes easy some things that are difficult to impossible with traditional phone networks.
