The Difference Between a VoIP Phone and Analogue Phone


Voice over internet protocol (VoIP) allows you to make phone calls that are able to bypass both cell phones and the traditional land lines. Instead, you are using the internet and your computer to make the calls. There are advantages to the VoIP method.


Long distance calls are either much cheaper or free, you can get your voice mail in the form of an email, and you can reach the user's main number by way of a toll free number. Land lines use an analogue system, and VoIP phones are digital. What is the difference between a VoIP phone and analogue phone?


Analogue phones are the land lines we have connected in our homes and offices. They are also the industry standard, having been around for decades. The first cell phones that came out were also analogue, but this is certainly not the case today. When you make a call using the traditional phone, you are utilising fiber optic networks.


Your analogue voice communications are converted to digital, and then back to analogue at the other end. Many interconnected switches stay open whether conversation is taking place or not. This is called circuit switching, which is very inefficient, since it doesn't make good use of the dedicated lines it follows.


When using VoIP technology over an IP data network, data packet switching is used instead of circuit switching. A data packet is made up of small chunks of voice data, which are transmitted only when speaking is taking place. The data packets are sent over any available internet circuit, rather than waiting to use a specific dedicated line. This improves efficiency and lowers wastage, both in terms of cost and energy.


Another difference between a VoIP phone and analogue phone is that the VoIP circuits are able to share network space with all kinds of internet information, simultaneously. The packet switching fits very well into the existing internet infrastructure. It sends and receives more calls than is possible over traditional networks.


This benefits business and consumers alike, because, in addition to being more efficient, it is extremely inexpensive (and even free in some cases) when compared to traditional phone networks. Good examples would be a digital phone service such as that provided by Skype.


When first introduced, the emergency services (999) were not available in VoIP systems, but it is now. The service providers are required by UK legislation to provide a location and call back number to the local emergency services.


For those who prefer the traditional handsets to using headphones or speakers and microphones, you actually can have both, by purchasing an IP phone. This phone has special connectors that plug right into your router.


One other difference between a VoIP phone and analogue phone is that your traditional land line is still usable when the electricity in your home cuts out. If you have a VoIP system, when you lose electricity, you also lose phone service. This can be avoided if you have a generator or UPS as a backup source of power.
