Digital Phone System Buying Guide

Are you looking to buy a digital phone system for your company? Are your planning to make the shift from analogue to digital? Before doing anything, take a few minutes to read this simple guide. We guarantee that you will be an informed buyer by the end of this post.

Analogue and digital

An analogue phone system is the regular phone system. It uses wires to transfer voice signals. The sole purpose of this system is to allow people to communicate with each other through handsets. Its functions are limited to call hold, redial, speed dial and mute.

Analogue systems have been around for decades, supporting both homes and offices. They are built on standard copper wires and the plain old telephone service phones. They are reliable and have good voice call quality.

Aside from the functions mentioned above, they may also be able to transfer calls between extensions but the features end there. This type of system is very simple and limited. It has almost no potential for expansion.

Analogue systems are expensive to support, configure and upgrade. If you need to change the location of an extension, you will need a professional to rewire it. Buying analogue is cheaper in the short-term but you will be locked into a closed system that requires adapters so that you can integrate it with VoIP and CRM (customer relationship management) systems.

Digital telephone systems are the modern telephone systems. A digital PBX is designed with a proprietary bus structure so that users can add features and capabilities. Boards are added to the cabinets of analog, digital or IP phones. Modular add-on boards can support features such as VoIP integration, on-hold music and alarm systems.

Versatile technology

Digital phone systems can bypass standard telephone circuits completely. Digital handsets normally offer an IP interface that enables the telephone system to integrate other features such as click to dial, desktop client, etc.

Some digital telephone systems are fully dependent on an IP network and are software-based. Others can be merged with analogue hardware with the use of an adapter. Most companies prefer a fully digital-software-based approach to their business phone system to do away with bulky hardware and cable wires which cost a lot of money to set up and upgrade.

Most digital systems being offered today offer an IP interface on the controller. This allows unified messaging features such as voicemail or fax delivery to email, voicemail transcription to SMS, desktop client and click to dial. This kind of system is called a hybrid PBX because it uses a combination of proprietary digital hardware and standards-based IP networking. A fully modern digital PBX is 100% software and IP-based.

Since a digital PBX does not rely on copper wire circuits, users gain more flexibility for additions, moves and changes. These changes can often be configured via point and click. Voice call quality is now comparable to analogue. It comes with all the basic features of an analogue system plus more such as advanced virtual auto attendants, call forwarding options and voicemail. It can also be integrated with a call centre or sales software.

The most important difference between an analogue and digital system are the advantages of software-based telecommunications solutions. There is a shift from hardware to software. Software controlled solutions offer more features and a superior upgrade path.

The future of digital phone systems

VoIP is the future of digital phone systems. It makes it possible for users to combine voice and data transmission over a single network. It makes unified communication in the workplace a reality. It has the ability to integrate all business and communication applications. It cuts down call costs and improves the company’s productivity and efficiency.

Another enhancement is cloud-based VoIP. This is an ideal option for small business that have limited space for an on-site server for a VoIP network.


When it comes to cost, the upfront cost for a cloud-based VoIP is less than that for a traditional phone system. Monthly charges are also significantly lower.

A VoIP system is scalable so you can easily expand it as your company grows. Since upgrades are software-based, there is less hassle when upgrading and business owners also do not incur a lot of additional costs. This means that even small businesses will be able to avail of features such as video conferencing, automated attendant and workflow management.

Should I go get a digital phone system?

Absolutely! Whether you are a large, medium or small business, you can benefit from this kind of system. Many advances in technology have made digital phone systems the best option for businesses. Wouldn’t you like a system that makes you look professional but is easy to setup, upgrade, takes up little space and can also lower your monthly bills?
