 Voice over IP (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks.  Because of the bandwidth efficiency and low costs that VoIP technology can provide, businesses are gradually beginning to migrate from traditional copper-wire telephone systems to VoIP systems to reduce their monthly phone costs  VoIP services treat all communications—such as phone calls, faxes, voice mail, , Web conferences and more.

Operational cost  Routing phone calls over existing data networks to avoid the need for separate voice and data networks  Costs are lower, mainly because of the way Internet access is billed compared to regular telephone calls. While regular telephone calls are billed by the minute or second, VoIP calls are billed per megabyte (MB)

Flexibility  The ability to transmit more than one telephone call over a single broadband connection without the need to add extra lines.  Integration with other services available over the Internet, including video conversation, message or data file exchange during the conversation, audio conferencing, managing address books, and passing information about whether other people are available to interested parties.  Secure calls using standardized protocols (such as Secure Real-time Transport Protocol)

 VoIP software is used to conduct telephone-like voice conversations across Internet Protocol (IP) based networks  VoIP software include service-backed applications Skype and other PC-to-PC applications

 The reason I have use this software is because of it’s quality, its every advance and professional software. If you download free you get Xlite, But if you purchase you get the ultimate Bria 3.0 as it showing below.

 Telephones for traditional residential analog service are usually connected directly to telephone company phone lines which provide direct current to power most basic analog handsets independently of locally available power  IP Phones and VoIP telephone adapters connect to routers or cable modems which typically depend on the availability of mains electricity or locally generated power. Some VoIP service providers use customer premise equipment (e.g., cable modems) with battery- backed power supplies to assure uninterrupted service for up to several hours in case of local power failures. Such battery-backed devices typically are designed for use with analog handsets  Also business should have normal telephone line running incase of VoIP computer power failure.

 traditional telephony security is outsourced the majority of these systems can be easily penetrated by hackers. A comprehensive risk management approach to VoIP security is required both voice security block and data being access, also farewell.  networks, accounts, voice mail and hosting, VoIP, risk management and recovery.  facility management, computer hardware and peripherals, software (non-proprietary), IT administration, risk management, software (proprietary

 Advantages of VoIP - Cost Savings & FREE Calls Every nature of VoIP technology means that everyone can make significant cost savings for their business - Portability - One Global Number It is should not be a distance or location dependent, you could be calling your supplier 1,000 miles away in Indonesia or calling your business partner on the other end of town - Integrated Communications  Making cheap local and international phone calls  Audio conferencing & Video conferencing  Have Voice messages sent to your  Call forwarding, call waiting  Fax thru  Send and receive multimedia files  Sharing photos while talking

 Disadvantages of VoIP - Power Supply Dependency in the future when most countries make a complete shift to IP based networks, and most Telco go 100% VoIP, this problems should by all means cease to exist. - Security Issues Security concerns, in my experience and opinion, will always be a concern, no matter how technology evolves - Quality Control The basics of VoIP is very different from regular PSTN, which uses “C7 signaling” for controlling quality of service - Recommendations In any small business or home office setting, you’ll typically have one broadband line which is shared by multiple users, for downloading data, sending s, and viewing web sites and multimedia applications. Add a VoIP system to that, and your bandwidth will soon be sucked dry

 As the popularity of VoIP grows, and PSTN users switch to VoIP in increasing numbers, governments are becoming more interested in regulating VoIP in a manner similar to PSTN services  VoIP is a telephony term for a set of facilities for managing the delivery of voice information using Internet Protocol (IP) and is the future of communication  VoIP implementations is the proper handling of outgoing calls from other telephony devices such as Digital Video Recorders DVR boxes, satellite television receivers, alarm systems, conventional modems and other similar devices that depend on access to a PSTN telephone line for some or all of their functionality

 This technology is able to determine the end system that will be used for a communication session, automatically sets the relevant parameters of the communication at receiver and user ends and then manages call transfer and call termination  When it comes to VoIP technology already available long-distance phone calls, conferencing, , and other communications are now affordable and flexible
