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.
The Session Initiation Protocol (or SIP for short) is the basis for a true VoIP solution since it plays well with others. With the wide choice of open source clients available, users don't have to both have to work with closed source clients in order to connect with each other.
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.
Using special compression techniques, this is how audio is sent and received over an IP network. End users have a wide choice of free applications available on their mobile and desktop devices in order to make phones call via the Internet. Phone calls made over the Internet using the SIP protocol always end up cheaper than those done over traditional phone lines and somewhat cheaper than proprietary VoIP phone systems.
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.
Getting started with using VoIP can be done in a number of ways. From hardware IP phones that connect directly to your broadband or local area network to software-based phones. The most cost-effective way to get connected is to use a soft-phone which uses your computer's hardware, requiring that it be turned on in order to work. Conversely, an IP phone connects directly to the Internet bypassing your computer which may take longer to set up at more cost.
The administration of call costs usually works out scalable and manageable for VoIP phone systems in general. For example, a company wishes to monitor its staff and see at a glance whom is making high volume calls at specific times in the month. VoIP phone systems based on SIP usually offer monthly itemised billing with no long contracts.
When comparing traditional Public Switch Telephone Networks (PSTN's) with VoIP phone systems we find that you can have your own phone line at any location where the Internet is available. There is also the added benefit of always being able to keep the same phone number even whilst relocating your VoIP phone line elsewhere. Finally, in the long run call costs in particular represent a huge saving over time when switching to VoIP.
