VoIP ("Voice over Internet Protocol") phone systems are not a recent innovation. They have been around for a while in common forms such as using the voice chat functionality in MSN, Google Talk, Yahoo Messenger, and even Skype. However, these are all proprietary systems. In other words, they don't talk (excuse the pun) nicely with each other.
The truest form of VoIP is based on the Session Initiation Protocol (SIP) largely because it does talk nicely with others. This means that instead of using a closed source client which both end users must use in order to connect, you have a wide choice of open source clients available.
With a similar philosophy to the open source movement, VoIP works out a lot cheaper for connection and call costs based on SIP when compared to closed source or proprietary protocols. Furthermore, end users enjoy a lot more flexibility in how they wish to place and receive calls whether it is via a software phone or a hardware IP phone.
To send and receive audio over an IP network, VoIP use special compression techniques. From applications that are freely available for desktop and mobile devices, users are able to make phone calls via the Internet. Making calls over the Internet using the SIP protocol works out reasonably cheaper than proprietary VoIP phone systems and especially cheaper than traditional phone lines.
VoIP operates by converting analogue voice calls into data packets for digital transmission over the IP network provider. There are many benefits to using VoIP such as the ability to make cost-effective international calls to setting up 3-way and conference calls.
VoIP can be set up in a number of ways. You can use a software-based phone or a hardware IP phone that plugs straight into your broadband connection or local area network. A soft-phone represents the cheapest way to get connection and requires appropriate computer hardware in place which in order to work relies on everything being turned on. Alternatively, an IP phone can be connected to your Internet connection at all times removing the need for a computer although can incur more cost and take longer to set up.
VoIP phone systems generally offer more control and scalability over the administration of call costs. For example, a company can see at a glance which users are making high volume calls at particular times during the month. Due to the nature of VoIP services using SIP specifically, billing is usually itemised on an ongoing monthly basis and unlike traditional phone services there are no long contracts to get tied into.
The overall benefit of using VoIP versus a Public Switch Telephone Network (PSTN) is that you can have your own phone line installed wherever there is an Internet connection available. You also have the added benefit of moving your phone line to a new location whilst retaining the same phone number. Lastly, in the long term you are likely to save a huge amount of money on call costs.
