ip telephonyCommunication is key. This age-old adage is one of the driving forces behind most of the technological progress we’re experiencing nowadays. From ultra-high-speed internet connections to new devices that let us get in touch with each other in ways that were previously unimaginable.

Telephony, from traditional telephone systems all the way to the cloud-hosted phone networks of the 21st century, has always been at the center of the communication revolution. It is especially important in the world of business, where offices make hundreds, if not thousands of calls, every single day, both externally and internally.

From traditional Private Branch Exchange (PBX) systems to the introduction of Voice over Internet Protocol (VoIP) technology, to the rapid development of Unified Communications (UC), the way we understand telephony in an office environment has changed dramatically in just a few decades.

The development of broadband Internet connection has brought significant changes to the world of office phone solutions, with the introduction of internet protocol telephony (IP telephony). IP telephony offers cheaper running costs and more advanced business phone features. It has made the traditional phone solutions all but redundant and established a new quality standard in the industry. If you want to know more about how it works and the potential benefits of IP telephony for your business, read on.

How Does IP Telephony Work?

IP telephony is a phone system made possible thanks to the VoIP (voice over internet protocol) technology. It enables users to carry out and receive phone calls via a simple internet connection, as opposed to the legacy landline systems, which made use of long, tangle-prone cables that were often difficult to install.

Legacy phone systems carry voice through landline cables by directly transmitting your analog voice signals and carrying them through to the addressee. VoIP, on the other hand, converts your analog signals into digital signals, or data packages, which are then sent through your broadband connection to the receiver.

These converted bits of data are known as packet-switched protocols. You can think of them as tiny, digital envelopes. In real-time, your voice is sliced apart, packaged into these “envelopes”, instantly sent to the addressee, and unpackaged so that they get the message. IP telephony calls can be transmitted via a regular internet connection, as well as a local area network (LAN).

Due to the fact that VoIP telephony makes use of the internet connection at your office to transmit voice signals across devices, before installing it, you’re going to need to make sure that your company’s broadband is up to the task, and that your office is equipped with SIP endpoints like IP phones or VoIP gateways to support your analog phones. Without the broadband connection and the right devices, IP telephony at your company will be all but impossible.

IP Telephony vs. Other Telephony Solutions

Of course, IP telephony is not the first (and probably not the last) communications solution that ever existed in offices all around the world. Traditionally, office telephony was done through the POTS (plain old telephone system) method. Every single phone in the office needed its own separate phone line connecting it to the service provider, as well as its own, unique phone number. As you can imagine, it caused a lot of confusion and was very inconvenient. After all, dialing a lengthy number when you’re in a hurry does not necessarily scream “efficiency”.

The first improvement upon POTS in offices were Private Branch Exchange systems, which allowed for call routing to different phones in the office via switchboard operators. They were human employees, who manually received each call and passed it onto the addressee by pressing buttons and re-plugging cables on the switchboard. It increased the efficiency of call-making in the office, and in time, it became the most frequently used communication system for the majority of large enterprises. Smaller businesses could also implement PBX for their business phone needs, but it often entailed having to enlist the services of a shared operator center, significantly slowing down the connection times.

This issue was resolved by the arrival of Private Automatic Branch Exchange (PABX) services, which worked in a very similar manner to its predecessor, except for the fact that it completely eradicated the need for the middleman, or operator, to transfer the calls. It was made possible by the creation of devices with buttons allowing for a wide range of call transferring options. All of the phones in one office were connected to one network, and in order to get in touch with a co-worker, all one had to do was dial their extension number, which was usually only one or two digits. PABX systems continue to be used by businesses around the world to this day, and the advent of IP-based telephony only made these solutions more efficient.

IP telephones are devices capable of connecting to the internet and take advantage of the possibility of carrying out voice communications via internet protocol. This has led to major improvements in call quality, decreased the influence of over-priced landline providers on the communications industry, and allowed for the implementation of plenty of additional features, alongside the basic phone calls.

Benefits of Using IP Telephony

Using IP telephony services can be incredibly beneficial for your business, regardless of its scale and the industry you work in. If you work for a major corporation, VoIP technology will allow you to seamlessly connect to the firm’s other branches all around the world. As for start-ups and small businesses, these establishments can benefit greatly from the money saved by making the switch from a landline-based PBX to IP phones.


This is probably the most frequently cited reason why CEOs and office managers make the switch to IP telephony systems. It’s simple: if there is an opportunity to save money, most businesses will take it. While changing to IP telephony requires providing each desk at the office with an IP phone, it is possible to implement this system even without such devices, given that most VoIP service providers also offer softphones that can be installed on smartphones and computers.

Regardless of how you choose to go about the device issue, the bottom line is that changing to an IP telephone service will save you hundreds, if not thousands of dollars annually when compared to landline-based business solutions .

Less Clutter Around the Office

Legacy telephone systems tend to require their users to accumulate a whole load of cables all over the office. It is one of the biggest drawbacks of traditional phone lines. It’s also one of the shortcomings that IP telephony has set out to fix. With an internet-based phone system, all you’ll ever need to make phone calls is a working internet connection.

More Extra Features

IP telephony not only fulfills all the functions of POTS (Plain Old Telephone System) without the loss of sound quality but also opens up plenty of possibilities for additional functions, including presence, video conferencing, instant messaging,etc.are all going to be within your reach with IP telephony.

Seamless Integration with Business Tools

One of the biggest doubts managers have when considering switching to IP-based phone systems is whether or not they will be able to integrate their new IP-based communication system with other business tools. Thankfully, doing so is even easier than in the case of landlines. Taking your phone system into the digital sphere means that all of the integration can be done almost instantly, with the help of your IT team. No need to bring in outside experts to install complicated equipment!
