Business Telephone Systems

Digital phone systems come in all shapes, sizes, and qualities


Digital phone systems come in all shapes, sizes, and qualities. Most Digital phone systems can be identified as KSU (Key Service Unit/Key System/Hybrid KSU), and PBX (Private Branch Exchange).

Key Systems (KSUs) are traditionally used by small to mid-sized companies because of their ease of use. A Key System has telephones with multiple buttons (“keys”) and lights that indicate which lines and phones are in use. When you want to place a call, you just press a button to access an outside line or an inside extension (phone).

As with most modern technologies, these systems have improved over the years and tend to blur the lines between VoIP, Digital, PBX, and Hosted. Some systems can now have a multitude of functionality.


As with most products, Digital phone system manufacturers make low, middle, and high quality offerings, with cost and quality typically going hand in hand. There are still some very good quality Digital phone systems that can fit the needs of most small to mid-sized businesses. The newer systems will have Automated Attendant and Voicemail built in, and both can be utilized as little or as much as desired.

These systems can also be very simple to use. Most businesses just want their phones to work and prefer not to take valuable employee time to learn all the many features and gadgets, many of which do not get used in day to day business communications. This doesn’t mean the features and gadgets are bad, just that many businesses still prefer to pick up their phone and press a clearly labeled button that performs the perfect function, placing or answering a business call.

VoIP ... "Voice over Internet Protocol "

The Future of Voice Technology

VoIP stands for "Voice over Internet Protocol " and it is quite simply a way of using the Internet to make and receive telephone calls. The primary reason VoIP is becoming so popular is cost and convenience; VoIP is significantly less expensive than typical local and long distance telephone service offered by traditional phone companies. Additionally, one high-speed Internet connection can serve for multiple VoIP telephone lines such as SIP or PRI.

Cloud Hosted Phone Systems are controlled "in the Cloud"

Cloud Computing applied to Voice Technology

Hosted phone services are controlled “off premise” where the VoIP equipment, servers and services are “hosted”, or controlled, by the VoIP provider, which manages calls and routes them to and from the subscriber's existing ‘on premise” telephones and network equipment. Hosted VoIP is also frequently referred to as managed VoIP and a big plus is that it can save companies from the potentially expensive costs of having to invest capital in digital or VoIp phone equipment and manage the system themselves.

Why the name “Legacy Telecom”?

It’s “Legacy” in the traditional sense, as in something of value to be passed on. This business was started with the idea of building a solid business that can be passed on generationaly . Many IT specialists see the title Legacy Telecom and mistake it for a company that mainly services digital and analog voice and phone systems that are being replaced by modern VoIP and Cloud Hosted phone systems and services. This is not the case, Legacy Telecom is still the go-to company for the newer cutting edge technologies such as VoIP and Hosted systems, as well as analog and digital phone systems and devices. As the CEO of Legacy Telecom, I attended VoiceCon 2000 in Washington DC, and though it’s been 19 years, Digital and Analog Telephony STILL comprise a very large segment of the Telecommunications footprint. Many devices utilized regularly in everyday business are devices that interconnect, such as paging, overhead music, entry access, door bells, and the list goes on. Not all of these integral functions of business are Ethernet based, so they cannot just be “plugged in” to a network rack patch panel or switch, they must be wired in by knowledgeable professionals.
