What Is a PBX?<\/h2>

A PBX (Private Branch Exchange) is a private telephone system that connects users within an organization (extension-to-extension) and routes external calls through the public phone network or the internet.\u00a0<\/p>

It\u2019s made up of hardware (or software, in modern systems) that links a company\u2019s phones to the outside world, and it also provides advanced features like call routing, forwarding, and management for both inbound and outbound calls.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Setting Up Your Telephone Network With a PBX<\/h2>

Setting up a PBX is no small task. A company must enlist the help of a systems administrators with decades of telecom experience. Plus, you need the physical space in your office to put the PBX system, like a closet or server room.<\/p>

The traditional telephone system is known as the Plain Old Telephone Service or\u00a0POTS<\/strong>\u00a0for short. It\u2019s based on the twisted pair of wires from the local phone company to the building. POTS is basic, reliable, and hasn\u2019t changed much in 140 years.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t<\/div>\n\t\t

Telephone service providers connect calls with others using the Public Switched Telephone Network (PTSN<\/strong>) on the Integrated Services Digital Network (ISDN<\/strong>) protocol. The PSTN makes it possible for a Verizon customer to call an AT&T customer as well as patch calls over locally.<\/p>

Providing a business with phone service can be expensive. A typical traditional business phone bill can easily be in the thousands every month just for a hundred lines.<\/p>

So people thought: There has to be a better way! And there is.<\/p>

PBXs allow a business to run its own internal\u00a0VoIP phone service<\/strong>, so employees can call each other through individual extensions without tying up outside lines. For external calls, the PBX routes traffic through a smaller pool of shared phone company lines, which reduces costs. Top PBX systems can manage voicemail, auto attendants, and recorded messages.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

PBX analogy: computer networks<\/h3>

You might have heard long ago that the internet was running\u00a0running out<\/strong>\u00a0of IP (internet protocol) addresses. To solve this predicament, someone would use a router within an office to assign internal addresses to each device.<\/p>

All those devices would then share the same IP address when interacting with the outside world. Home and business routers have effectively eliminated the concern of running out of IPs and added more\u00a0security<\/strong>.<\/p>

The same approach applies to a Private Branch Exchange. It\u2019s a phone network that serves employees but shares the same outbound channel when they dial out. Internally, employees can use any phone extension, but they share a finite set of\u00a0business phone numbers<\/strong>\u00a0externally.<\/p>

A modern alternative<\/h3>

Cloud-based PBX has redesigned how businesses handle phone calls, offering a significant upgrade to past limitations. Before, PBXs were proprietary and very difficult to maintain. Today, we have modern PBX systems that have evolved quite a bit.<\/p>

No longer beholden to the local telephone company, calls are made using Voice over Internet Protocol (VoIP<\/strong>) technology. Instead of analog lines,\u00a0SIP trunking<\/strong>\u00a0can establish connectivity for a fraction of the cost.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The purpose of a PBX<\/h3>

The primary purpose of a PBX is to serve as a business phone system.<\/p>

It allows for the internal management of phone calls within a smaller area, such as an office or business. A PBX can handle any feature like voicemail, auto attendants, and recorded messages, providing a comprehensive phone system for the organization.<\/p>

In contrast, the PSTN is a public phone network that connects calls between different providers and handles the routing of calls on a larger scale. It\u2019s not specifically designed for internal business phone systems like a PBX.<\/p>

PBX systems empower IT leaders to maintain their existing devices with an all-digital backbone by assigning different business phone numbers to different extensions. Alternatively, a\u00a0cloud PBX<\/strong>\u00a0blends the best of both worlds with a fully managed phone system deployment.<\/p>

PBX System Benefits for Businesses<\/h2>

It\u2019s not every day that businesses specifically want to\u00a0set up their phone system<\/strong>. There has to be something in it for them to move their phone service to the cloud.<\/p>
