This Article has been written to assist Technology Decision Makers and Business Owners in understanding the market landscape and the tradeoffs in the area of Business Phone Systems in NJ.
A Business Phone System or PBX is a collection of office phones and a system that allows them to communicate with each other and the outside world. Above all else the functionality that defines a Business Phone System or an Office Phone System is the ability to dial from one phone on the system to another phone on the system. This functionality alleviates the need to buy additional phone lines from the Telephone Company when you add more employees and phones to your business. It also alleviates the need to pay the telephone company for these internal calls.
At the heart of a Business Phone System is the ability to place internal calls.
A Business Phone System or an Office Phone System facilitates placing internal calls between two office phones located at your business. This functionality is at the core of a Business Phone System, however they have evolved to include a wide and varying set of features. I will not attempt to list all of the features here. Here is a bare minimum list:

The Traditional Business Phone System is installed at the business premise in what is often termed the "phone closet." This phone system requires a connection from your Local Telephone Company of PRI or POTS. This type of Business Phone System also requires what is called a "home run," a physical cable run between the phone system and each phone. The phone system communicates to the phone using a proprietary analog or digital connection. It is this communication protocol that prevents you from using any other manufacturer's phones with this type of Business Phone System. This is often termed, "Manufacturer Lock-In"
This is the type of Office Phone System that has dominated the new sales market up until about the year 2000 when they started losing ground to the phone systems covered below. Most of the installed phone systems around the world still fall into this category, however most newly sold Office Phone Systems have been migrated to VoIP.
Note that this type of Phone System requires you to order and maintain the connection between your phone system and the Telephone Network. This type of phone system also requires you to maintain a support agreement with an outside vendor, who will drive in and make repairs periodically on the PBX in your "phone closet." Generally speaking, you are relying on three companies to make this solution work:
Example: Samsung Ubigate iBG Series or Toshiba IPedge
In the last decade the Legacy Business Phone System received an upgrade. This was the addition of VoIP functionality. Much like the legacy phone system, A VoIP Phone System is still installed on the Business Premise in your phone closet. A VoIP Phone System also still employs a proprietary protocol between the phone system and your phone, preventing you from mixing and matching phones from different manufacturers. In other words, this did not address the Manufacturer Lock-In issue. Adding VoIP to the legacy phone system provided a number of benefits over the Legacy Office Phone System. The "home run" wiring mentioned above, was now mitigated, alleviating wiring expenses. This was mitigated by placing LAN switches throughout the office, which could aggregate the phone wires and reduce the number of "home runs" needed. Now the network of cables in the premise could look more like a tree or a graph, where as the legacy business phone system had wiring that was more like a star.
This type of Phone System has the same support characteristics as the older, traditional PBX, in terms of the companies you rely on to make your business phone calls. Namely:
This is the fastest growing area of Business Phone Systems. This is the first type of phone system where there is no system in the closet on the premise. Instead, the phone system is provided as a service. VoIP functionality provides a way to set up calls between two phones via an Internet Connection. This means that, using VoIP, the entire core functionality of the business phone system can be moved to the cloud without changing the user experience and functionality of the system. This brings a host of benefits that businesses are familiar with through moving other services to the cloud. At the Business Premise there are VoIP Phones, which connect over the internet to the Hosted PBX. This type of Phone System moves a great deal of the responsibility and technical details of the Phone System into the network. Additionally, where as previously internal calls only relied on components at your physical premise, now all calls rely on your external connections and providers. For this reason and others we think it is important to draw a distinction between the two types of Hosted PBX Providers within this category.
One Company Approach: ISP & Local Telephone Company & Hosted PBX Provider
Example: Monmouth Telecom
With all types of Phone Systems described here, you have to be provided service by a Local Telephone Company. This is an unavoidable fact of life. Additionally, modern businesses require an internet connection. Most often, both the internet and the telephone service is provided by the same company. Monmouth Telecom is an example of a Service Provider who provides Hosted PBX as a service, in addition to Telephone and Internet Service. This allows you to only rely on one Company to ensure your calls work and have good quality.
Two Company Approach A.K.A. Bring Your Own Bandwidth
Example: Ring Central
This type of Hosted PBX Provider requires you to use your own internet connection. This means that you have two contracts with two vendors. One is your Internet Service Provider, and the other is your Hosted PBX Provider. You rely on both of these to do their part for your calls to work and have good quality. You also rely on an unknown number of intermediate Internet Carriers between your Internet Service Provider, and the Hosted PBX Provider. The barrier for entry is very low for this type of business. These types of services are making headway in SOHO (small office home office) environments, where poor call quality and indeterminate outage times can be tolerated. The lack of QOS (quality of service) or prioritization on the VoIP reduces the feasibility of this type of service for businesses who require guarantees on quality.
Premise Based Phone System Manufacturers
These include some of the largest players in the game. Cisco, Avaya, Panasonic, Toshiba, these are all Premise Based Phone System Manufacturers. Many of them have been manufacturing phone systems for decades, some have entered only with the advent of VoIP. These companies produce both the software, and the hardware associated with their Phone Systems. These companies do not sell or support phone systems directly to Businesses but instead through distributors and vendors.
Premise Based Phone System Vendors, Distributors, and Maintainers
The manufacturers listed above rely on these vendors to sell their phone systems and enable them to make a business on the mark up. They also often provide, at a cost, maintenance and support of the phone system. The companies that provide this service in the food chain are generally small, local businesses compared to the manufacturers of the phone systems, which are typically multi-national corporations.
Second-Hand Hardware Market
Manufacturers are constantly discontinuing older models. When this happens, owners need to purchase spares and upgrades through a second hand hardware market like E-Bay.
ISPs and Telephone Companies turned Hosted PBX Providers
Local Telephone and Internet Service Providers are more and more providing Business Phone Systems as a service to their customers. By providing it as a service, the maintenance and support of the phone system is also provided as a service.
Bring your own Bandwidth Providers
Any company with an internet connection and a website can sell Hosted PBX over the "Public" Internet.
With the advent of VoIP, It became possible to provide all of the functionality of a Business Telephone System without any physical presence at the customer premise. There is cost and disadvantages associated with the physical presence of the Business Telephone System on the premise of the Business, and as such, by eliminating the need to locate the Phone System there, VoIP has enabled the Hosted PBX revolution.
