You must have heard about VoIP and VoIP gateways. But do you know what these technologies actually are all about?
To understand what a VoIP gateway is, you first need to understand what VoIP technology is all about. VoIP is the term used for Voice over Internet Protocol . It refers to the technology which facilitates transmission of voice traffic over internet networks. Internet protocol was originally developed for sharing data. After its immense success, the technology was adapted for sharing voice networking.
More and more business organizations have started to use VoIP instead of the traditional PSTN for communicating because it is cheaper and more useful than the other mediums of voice communications. Some of the benefits of using VoIP technology and VoIP phones include:
VoIP facilitates to transmit more than one phone call on a single broadband phone line. Therefore, more telephone lines can be installed by the business at a lower cost.
Like business phone systems, VoIP phones too, have many advanced features such as call forwarding, caller ID, call waiting etc. For these features, the businesses do not have to pay any extra charges.
VoIP offers unified and secured communications, which can be integrated with other internet based services such as video conferencing, web conferencing etc for enhancing the business communication.
Now let us discuss what is a VoIP gateway. Gateways are devices which convert telephony traffic into internet protocol so that data can be transferred over a network. These are generally used in the following two ways:
1- For converting PSTN to VoIP. A VoIP gateway facilitates receiving and placing VoIP calls on a regular telephone network. With the VoIP technology, businesses can make larger volumes of calls at much lower prices.
2- To connect traditional PBX and other business phone systems to an IP network. A VoIP gateway allows making a call using VoIP technology instead of a regular telephone line. Business can either buy these services from a reputed and reliable VoIP service provider or can route the calls through the internet to reduce the call charges.
VoIP gateways are available in the form of external units and PCI cards. However, most of the business organizations prefer using the external units as their VoIP devices. Every VoIP gateway has a connector for getting connected to the IP network and one or more number of ports for connecting the phones lines to it.

Benefits
- A SIP-trunking service benefits companies by:
- Eliminating the need to invest in costly (and less capable) TDM-gateway equipment infrastructure or desktop equipment.
- Nullifying the need to purchase equipment, such as managed-media gateway devices, to interface between IP voice and the PSTN.
Small, family owned stores or large “big box” retail businesses all suffer the same problem: theft of money or inventory. Last year, alone, retailers brought in more than eight hundred billion dollars, but lost more than two hundred billion to “shrinkage.” This shrinkage may result from outright, gun-toting robbers, to shoplifters, to untrustworthy employees.
In certain areas, vandalism can be a serious and costly consideration. Whatever the cause, Loss Prevention Equipment can significantly reduce or prevent such occurrences, and help local law enforcement successfully respond to those thefts that do happen.
Loss Prevention Equipment and technology have evolved rapidly in the past few years. There is a wide variety of sophisticated loss Prevention tools now readily available that allow for cost-effective configurations to suit virtually any retail business budget.
Depending on the availabilty of the the resources available for dedication to Loss Prevention Equipment, one, or a combination of the foregoing can provide a viable solution to your security needs.
CCTV or video surviallance systems, whether used with one camera, or a series of cameras, send its feed to a monitor or monitors, or a choice of recording devices. They can be hard-wired or wireless.
Cameras come in a very wide variety of shapes and sizes, from those that are conspicuously mounted to provide observation and deterrence, to small, virtually undetectable units, which can be used to monitor cash registers or other highly-sensitivity locations. Some are designed to automatically sense and adapt to varying lighting condition, while others are specialized to accommodate consistent dim lighting. Color or black and white transmission options are available. Dome cameras, similar to what may bee seen in casinos, located in ceiling areas, also allow for great coverage.
Single monitors can be configured to work in conjunction with multiple cameras, providing a “flip” sequence of images of specific areas; alternatively, several monitor can be linked with several cameras to provide constant surveillance of “hot spots.”

While closed-circuit television (CCTV) or video surveillance systems have often sparked debate around personal privacy issues, they are often used by some individuals and business owners as a deterrent for crime. It is important to recognize where the system is set up so that it does not cross the lines of privacy in areas where there should not be monitoring.
Digital Video Recorders (DVR) record videos that are in digital format to a medium. A disk drive is a sample of this medium. DVRs come in a stand-alone set-top box that is connected to a monitor or television set for viewing. By connecting a digital video recorder to your video surveillance system, you can easily record the images captured by your security camera.
Telephone technicians play a crucial role in the proper repair or installation of your new business phone system. There are many technicians available for the task. However, there are fewer that truly meet the criteria for excellence that today’s integrated phone systems demand. The test of a good phone technician is not just expertise and experience, but also respect for the customer and good interpersonal skills.
Samsung Prostar is a discontinued model, but still a big seller in the used and reconditioned phone marketplace. These phones are often referred to as hybrids, which means that they use both conventional switch technology and digital integration with your PC, PDA, and other digital devices. These phones are a great in-between step for growing businesses for which big, network-driven phone systems aren’t practical, yet wants to keep up with the exciting new changes in technology.
A SIP (Session Initiation Protocol) trunk is a service that allows businesses with an installed PBX to use real-time communications including VoIP. By connecting a SIP trunk to an internal traditional PSTN (public switched telephone network) phone system, companies can communicate over IP outside the enterprise. In addition, companies can replace traditional fixed PSTN lines with an IP phone system connected externally through an SIP-trunking service, thereby creating a single conduit for multimedia components including voice, video and data.
It’s not a surprise that Voice-over-Internet-Protocol (VoIP) has become a great asset to many people around the world.
