First, let’s look at how traditional telephones work.
Until recently, any call you placed traveled to its intended recipient via physical copper wires connecting homes and businesses and/or via cell phone towers. This setup is known as the Public Switched Telephone Network (PSTN).
As you can imagine, setting up a business to operate on the PSTN can get expensive. Imagine setting up a dedicated telephone line with copper or fiber-optic wires for every employee. To combat these costs, businesses have the option to connect to the PSTN via private branch exchange (PBX).
A PBX allows the business to connect a hub to the PSTN and then allows employees to connect to the hub with their phone extensions.
So, now you’re probably wondering, what is VoIP, and how is it different?
When you place a call using a VoIP phone solution, your analog voice is converted into a digital signal and sent to the caller on the other end. And the endpoints of a VoIP call can vary; you can place calls on your cell phone, specific VoIP-enabled phone handsets, tablets, computers, or from a website.
Let’s get into some specifics as we look at exactly how VoIP works.
When you place a call using a VoIP system, your analog voice is converted into digital data packets that are then sent across the internet to the intended recipient, reorganized into the correct order, and converted again as what the recipient hears on their end.
That’s right. That happens again and again throughout a VoIP call, and with the right VoIP provider and good internet service, you won’t be able to tell the difference between a VoIP call and a traditional call.
A VoIP phone system uses VoIP technology to provide users with an inexpensive, easy-to-install option for their telephony needs. In addition to phone calls, VoIP phone systems also provide users with many additional features (don't worry, there's a section on features coming up.)
VoIP phone software can integrate with other software applications for your business, like accounting tools, warehouse management programs, and CRM systems. Some VoIP phone solutions can also help you pare down the number of applications you use every day. Look for a service that offers messaging, video capabilities, analytics, and contact center options.
You'll be amazed at what programs you can integrate with your VoIP phone system or do away with entirely because the VoIP phone provider includes it in their service.
Like a traditional PBX, IP PBX systems use a central PBX system installed in a company to connect employees to the PSTN. However, in an IP PBX setup, the phones connecting to the PBX are VoIP-enabled devices, not traditional telephones. This helps companies save money while transitioning to a fully VoIP-enabled model.
An IP PBX phone solution may use a hybrid model that incorporates traditional and VoIP technologies, but most IP PBX solutions can use a full VoIP or cloud infrastructure.
A complete VoIP solution means that from the get-go, you're committing to a completely VoIP setup, whether that means you're ditching your analog phone setup or you're starting from scratch. You most likely won't have expensive startup costs or installation with this option.
