VoIP (“Voice over Internet Protocol”) phone systems are nothing new. They already exist typically when using the voice chat functionality in MSN, Google Talk, Yahoo Messenger, and even Skype. Since these are all proprietary systems, they don’t talk (excuse the pun) to each other nicely.
VoIP based on SIP (which stands for Session Initiation Protocol) is a ideal solutions because it talks nicely with others. So instead of using a closed source client, the end users can connect with each other using a wide range of open source clients.
In the spirit of the open source movement, VoIP connection and call costs based on SIP are far less to the end user than closed source or proprietary protocols. Furthermore, the end user has flexibility in choosing the ways they wish to make and receive calls either with software phones or actual SIP compatible handsets.
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 provide increased control and scalability for the administration of call costs. For example, a company monitors its employees to specifically see at a glance whom is responsible for making high volume calls during a given month. No long contracts and detailed monthly itemised billing is an inherent quality of VoIP phone systems based on SIP.
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.
