There is a lot of hype about VoIP phone systems these days. Many businesses are moving from landlines and incorporating VoIP phone systems into their corporate infrastructure. However, implementing VoIP technology in your company is a big investment and many business owners, because they are still unfamiliar with the details of the technology, refuse to implement VoIP technology in their company. If you are still wondering what VoIP technology actually is and how it can help your business, this post is for you.

VoIP vs. Landline


Landlines are built upon local phone networks, connected to that network via a physically wired connection. When making a call on a landline, your voice travels along a ​copper wire to the telephone poles of your local telephone network. Those telephone poles transmit the call’s analog voice signal through a series of switches and circuit (circuit switching) until it arrives at the receiving party. To connect to a landline, you are required to connect to a phone jack that then connects your analog signal to the physical phone lines.


VoIP Voice-over-Internet-Protocol (VoIP) phone systems use the Internet, instead of a phone network, to transmit your calls. While landlines use analog voice data, VoIP convert those analog signals into a digital format that is carried through Internet in network data packets. To connect to your VoIP network, you just need a reliable, high-speed Internet connection.

The Benefits of VoIP Over Landlines


To configure a landline, you often have to use a dial pad with the telephone display. This non-intuitive setup is in sharp contrast with VoIP configuration processes, which often uses a browser interface with user options. VoIP configuration also doesn’t require a technician to physically visit all of your company’s locations, instead of​ managing the phone systems from a central, cloud-based admin interface.


Moving office locations, for a company with a landline, is a nightmare! The dependence on the availability of a physical phone line in the new space means that you must either limit your options to older buildings or pay hefty installation fees for the physical phone line in the new building. With a VoIP phone system, your phone system can be moved and transferred to any new location with a reliable, high-speed Internet connection. Furthermore, you can access your VoIP network from anywhere in the world (with a high-speed Internet connection) and configure your VoIP network to be available on mobile devices as well (through extension forwarding).


To set up a landline, you often need a schedule a visit with a telephone technician so they can configure and connect your telephone to the telephone network. This can waste much time and money for businesses who have to manually configure and test each phone in their company. To set up a VoIP phone system, all you need is an internet connection and access to the cloud-based interface. While the
phones obviously need to set up for use, from the cloud interface you or your IT team can configure the VoIP network. Because VoIP phone systems are dependent on your internet connection, it is very important to have a quality Internet connection. There are various limits to the number of VoIP phone lines supported by the different upload speeds. For instance, 500 kbps has a maximum number of 5 lines supported, however many telecommunications companies advise to only use 1 VoIP phone line on a network of this speed.


On a landline, your call has a dedicated path to its destination, making it pretty hard for that call to be intercepted while it is in transit. This characteristic, along with the fact that almost all companies are using VoIP phone systems, means that your attack surface is very low, although the possibility for attacks does still exist. On a VoIP phone system, however, the voice data is turned into digital network packets and travel through the Internet. This makes it an easy target for hackers since they can access from across the world, just like you! One of the main safeguards against hackers on a VoIP network is to use encryption with your VoIP network. You can speak FATPBX regarding the specifics of encryption technology for VoIP phone systems.

Quality & Reliability

On a landline, your call quality won’t be as high, but it is pretty consistent. The occasional issues are encountered, just like any system, but these systems generally have a predictable quality. On a VoIP network, the quality of the calls depends on your network connection and speed. If you decide to use a VoIP phone system, it is important to make sure your existing network connection can support VoIP technology.
