Author: In a family with several children, it’s not very good to compare them with each other. Oftentimes this will result to a feeling of enviousness and rivalry. They would also try to compete for their parent’s attention. Comparing can be very harmful to the kid’s relationship towards each other.
Comparing things can be useful if you’re trying to compare a VoIP service provider. And this goes true even to different businesses offering products and services in order to attract customers; they want to compare their products/services against a competitor. Whichever provider that comes out best will get the fairer share of the market.
This is one reason why all business owners have developed ways to attract prospects, including all VoIP providers. But do you know what VoIP is?
The main technology responsible for internet phones is the voice over IP, more popularly called VoIP. As its name implies, this new technology allows any person to make voice conversations over the IP network.
Through VoIP, a P2P session is established by optimizing protocols as a group. This will result to an uninterrupted stream of digital data carried through the net. The two VoIP protocols which are now widely accepted are the open standards and the session initiation protocol or SIP. Voice signals are continuous in nature, and so it requires this session.
Now, three internet phones are being used, namely: PC softphone , VoIP handset, and the ATA or the analog telephone adapter. The first one is a software that makes use of the computer’s sound card, speakers, and microphone. The VoIP handset relies on your personal computer and is more complex than the first one. The ATA will not require you to have a personal computer because the high-speed internet connection is directly connected to it. These internet phones also have different softwares.
VoIP providers use any of the three phones and software. So if you have preferences especially with the hardware, you have to compare different VoIP providers. By comparing them, you will be able to choose one that has almost all your needs.
The VoIP provider is responsible for the initiation of P2P sessions. Aside from that, they also associate the telephone numbers to different IP addresses, and route VoIP data to other personal computers, to the mobile number or landline number that you’re trying to call.
Although VoIP providers differ in their hardware and software being used, the process of making a call is still the same. They only differ on the hardware’s processing.
Not all people are ready for this new technology. They still compare it with their long-trusted conventional telephone. In comparing these two, the biggest difference lies on the costs. With VoIP, you can surely cut down your monthly phone bills. VoIP is often associated with ‘free’ calls.
VoIP service is well-known for free calls for promotional or trial basis. However, when you sign up for their service, you will be asked to pay low-cost plans to enjoy the service. But this cost is lower than that of traditional phones.
Since VoIP is still new in the market, other people want to rely on their traditional phones for reliable connections and exceptional sound quality.
In doing a comparison between a traditional phone and voice over IP, you can see their advantages and disadvantages over the other. If you try count each of their good and bad aspects, you can come up with a good decision. It’s either you settle for VoIP or remain loyal to your traditional phone.
You alone can compare these two services. If you have a regular phone, why not settle first for a free trial period? Look for a VoIP provider which offers such service, you can find a lot of them on the internet. After the trial period expires, make the decision. Trying it yourself can give you a clearer view of how VoIP works.
If for some reason, you’re not satisfied with the result, then continue with your traditional phone service.
Comparing VoIP and the regular phone service will only be effective if you know what you need in a phone service. Most people who go for VoIP are the ones which want added features on their phone, one that only VoIP providers can provide.

VoIP is short for Voice over Internet Protocol. It is the method of connecting other technologies that let all IP networks be utilised for certain voice applications, including teleconferencing, telephony and voice instant messaging.
VoIP provides a solution to nearly all the layers that make up an IP network ranging from specialised voice applications like Skype through to those low quality measures that are there to ensure the applications are running as they should be.
VoIP is used in many different companies around the world, as well as in some households, particularly those that run businesses from home.
In many cases people talk about a Voice over IP. Voice over Internet Protocol use technologies that allow certain voice communications through IP networks, like the World Wide Web. Creative entrepreneurs and developers have developed entire businesses based on the VoIP technology in the many forms, including telephone services, corporate telephone systems and desktop applications; all of which are things are used in most businesses every single day.
VoIP is a core technology that can work in almost any environment; from software found on a desktop computer to Mac IP based telecommunications networks in very big businesses. VoIP serves different purposes for different people and offers a range of benefits. For the homeowners, VoIP can help to save money on their phone bill each month.
VoIP technology goes back some time. VoIP was slowly introduced since the early 1990s, but it has taken time to develop and distribute it. The creators and the first to use VoIP would have to first figure out exactly what it is and what can be done with it is before it was released it to the public. As long as there is an internet connection, then people are able to use VoIP.
The first users of VoIP use to sometimes get frustrated with the programs and the bad sound quality they received. This is why some of the very first VoIP products failed on the markets and had to be taken off. Since VoIP has been correctly optimised and developed with more people are learning to understand it, communications have become cheaper and easier for people throughout the world.
Over future years it is expected that VoIP will become well established especially with the associated benefits which include, cost savings, increased worker productivity and application integration.

The Voip Co Guide to SIP Trunking & What SIP Trunking can do for your Business
The Voip Co SIP (Session Initiation Protocol) trunk is a service that allows businesses with a Hosted PBX or an installed PBX to use real-time communications including VoIP. By connecting an SIP trunk to an internal traditional PSTN (public switched telephone network) phone system, companies can communicate over IP outside the enterprise. What’s more, 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. As a result, an SIP-trunking service typically delivers greater cost savings and increased reliability for Business VoIP solutions.
How SIP Trunking Works
SIP trunking blends connections for both data and voice into a single line. By serving as a converter between a legacy phone system and a company’s Internet connection, an SIP-trunking device allows the data network to carry voice traffic. SIP-trunking features typically include local and long-distance calling, E911, directory listing and caller ID, all of which integrate into a company’s existing phone system.
Here’s a hypothetical example of how SIP trunking works: A San Francisco-based sales representative places a long-distance call to a client based in New York City using a dialing prefix and the local-area phone number. The call either originates as an IP call or is converted to one before it leaves the office and then travels the majority of the way over the IP network of the service provider, then drops back down to the PSTN once it reaches its termination point. Since a sizable portion of the call traveled over the IP network at no additional cost rather than on the PSTN, the service provider can (and does) charge a mere fraction of what the traditional fee would be without the IP connection.
SIP trunking consists of three primary components. These include:
IP PBX: An IP-based PBX communicates with all endpoints over an IP network. It also switches calls between VoIP users on local lines while allowing all users to share a number of external phone lines. The typical IP PBX can additionally switch calls between a VoIP user and a traditional-telephone user, or between two traditional-telephone users in the same way that a conventional PBX does.
The Voip Co is an ITSP (Internet telephony service provider): The role of an ITSP is to ensure connectivity to the PSTN from an IP network for mobile and fixed communication devices. It also transports IP communications across a private IP network or public Internet.
Border element: The border element facilitates connectivity between an enterprise IP network, the PSTN and an external IP-carrier network. The border element may be an SIP-capable firewall or a SIP-enabling edge device connected to the firewall, or it can be a switch to transfer calls into and out of the PSTN. Border elements are usually managed by the service provider.
Note that a service provider will typically include SIP trunking as an element of an IP-phone-system package; it will only be separated into hybrid solutions when there is a need to maintain some locations on a traditional TDM (time-division multiplexing) system, which will connect to the overall IP infrastructure through various border elements and an SIP-trunking service.
Benefits
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
• Reducing monthly expenses, since only one connection for data and voice is needed
• Eliminating the need for PRI (primary rate interface)/BRI (basic rate interface) connections, lowering telephony costs
• Allowing companies to outsource their PSTN connectivity to a third party, reducing long-distance charges
• Providing points of presence in multiple U.S. cities so that companies can establish local numbers rather than rely on a 1-800 number
• Accessing the benefits of a hosted VoIP service, without discarding existing investments in a traditional phone system
Costs
Although SIP-trunking service providers offer many options at varying costs, it is not uncommon for companies to realize instant cost savings from a relatively modest investment in SIP-based technology. Certainly, SIP requires purchasing services and products including an IP PBX, IP phones, soft clients and SIP-friendly firewalls, to name a few out-of-pocket expenses. But if deployed properly, The Voip Co Hosted PBX SIP trunking can produce a healthy return on investments in less than six months.

It is clear that there are many merits to VoIP for a company and reasons to use it, but it is important to know that just choosing your provider isn’t where it ends.
You need to be sure that you know what kind of telephony equipment is right for you and your company in order to truly benefit from Voice over Internet Protocol.
This article will give you an idea of what hardware devices you can use for calls over an IP network and which ones suit your needs better.
Soft phones (USB phones)
There are some VoIP equipment solutions that simply need a computer and an internet connection to work. The computer will obviously need decent audio equipment like a sound card, speakers or earphones and a microphone.
The software needed is simply installed onto the computer and then IP calls can be made. This is usually charged at a monthly rate or per call and only tends to work PC to PC. The best known software based VoIP telephony equipment is Skype.
A USB headset or soft phone can be plugged in directly to your PC USB port enabling you to either talk via a phone or a headset – depending upon what you prefer.
There are many different styles of handsets, desksets with speaker phones as well as some cordless models.
Hard phones (IP phones)
A hard phone is typically more expensive than a soft phone. It looks like a conventional phone and plugs into an Ethernet port on a router. The hard phone then communicates directly with the VoIP server and doesn’t need to go through a computer – which means that you don’t need any software.
A Wi-Fi phone is another variation on the hard phone and has a built in wireless transceiver in addition or instead of an Ethernet port. The VoIP system then connects wirelessly to a Wi-Fi base station. Again, it doesn’t have to connect to a PC.
Other options to hard phones, are ATAs (analogue telephone adapters), which allow you to make VoIP calls using your regular analogue phone. Another are DTAs (digital telephone adapters), allows businesses with PBX to use their existing infrastructure for VoIP calls, and integrates with any handsets already used by the company. VoIP interface cards go into a computer’s PCI slot and add VoIP capabilities, whereby you can plug several phones into one single card and VoIP gateways connect VoIP networks to their PSTN system, which enables calls to be made between VoIP phones, PSTN and mobile phones. The final system that you could use is a VoIP PBX which is the same as a traditional PBX, but uses a live operator to route the calls.
Whatever system you use, make sure that it is right for your company. If you are a small organisation, then a soft phone would probably work for your needs, but if you are a large company, then getting a fully integrated system will probably be the best bet to save you money and improve your communications.

With so many choices of surveillance cameras in the market, it is easy for a consumer to get overwhelmed in choosing the best security camera for their system needs. No matter what type of surveillance application you are installing, there are some basic things that all consumers should consider in order to make a good choice. This will be the first of a series of articles to help guide a non-technical person that is researching the purchase of a surveillance system. The main topic for this first article of the series is security camera resolution.
It is important to know what resolution means when shopping for a surveillance camera. CCTV cameras have a resolution range from 330 TVL (television lines) to 600 TVL. For color resolution, CCTV cameras max out at 560 lines, however you can get black and white CCTV surveillance cameras in 600 TVL. IP security cameras are now available in much higher resolution, up to 5 megapixels. What does this mean?
In the United States, regular TV transmission (not high definition) displays 480 lines of resolution. So it is possible to purchase CCTV cameras that can record equal to or greater resolution than TV. Obviously the higher the resolution of the camera that you choose, the more detail you will see in your surveillance video. High definition television (HDTV) displays either 1080 or 720 lines of resolution depending on the channel and the type of HDTV that you have. In order to get higher resolution from surveillance cameras, the only choice is IP based megapixel cameras, which connect over an IP network instead of a closed circuit. Generally, IP mega-pixel cameras are much more expensive than CCTV cameras. For high end applications that demand ultra-high resolution, megapixel cameras can capture surveillance video at more than twice the resolution of high definition television.
Some people that are shopping for a security camera are unrealistic (because of their lack of experience) about what a surveillance camera can capture (especially CCTV cameras). I will go into more detail about lens types and sizes in the next article in this series. I must touch on it briefly now as it is so closely related to resolution. For this example, we will use a 3.6mm lens which gives you about a 90 degree field of view outward from the lens. Some people think that if you take a 480 lines of resolution camera with a 3.6mm lens that you will be able to get a clear picture both of an object that is 20 feet away and an object that is 80 feet away. This is not true. While the 3.6mm lens will easily pick up the object in detail at 20 feet away, it cannot pick it up at 80 feet away also with the same 3.6mm lens. In order to pick up the object at the further distance, you have to either use a larger lens that would make the image appear more close up or use a high end megapixel camera that would allow the operator to zoom in digitally without distorting the picture. Digital zoom is possible with high end megapixel cameras, but not with normal resolution CCTV cameras. Because of the huge price difference between CCTV and IP mega-pixel cameras, a lot of times it makes sense to add additional CCTV cameras instead of upgrading to megapixel cameras. This will lead us into the next article which will be about understanding and choosing the right camera lens.
