What is Business VoIP?

Business VoIP, also known as Business Voice over Internet Protocol, is a phone system designed to match your business calling needs.

VoIP for business uses your high-speed Internet connection to make and receive phone calls, offering businesses of any size the features and flexibility that they require to effectively manage their employees and customers.

Service options are available for both business and residential use. However, there is a major difference between the two: business calling plans have more of a focus on tools and enterprise features that businesses need to succeed, while residential calling plans have basic features and standard inbound/outbound calling. 

Business VoIP is a way to make business calls via your broadband Internet connection instead of using traditional phone lines. Choosing a service plan is much more than just replacing a traditional phone line, though. These phone solutions include a PBX phone system along with advanced productivity and call management features.

While PBX phone systems and advanced productivity features are often considered add-ons with traditional phone companies, they are included with service. Furthermore, most of these providers also offer you the flexibility and mobility that a traditional phone company simply can't provide. Do yourself a favor and compare these different business phone service providers with your current phone service provider to see how they match up.

What is a PBX?

A Private Branch Exchange (PBX) is a specialized phone exchange system that routes inbound and outbound calls.

A PBX is a type of phone network that helps businesses manage calls within their network and calls to outside users. This includes routing calls between office extensions as well as routing incoming and outgoing calls. Any office with multiple extensions (and therefore, users) will need a good PBX system to function properly. If you already have a legacy equipment, then you know how costly a PBX can be. The machinery for a legacy PBX can run upwards of $10,000 depending on your business size. And when you add in costs for repairs, installation, manual operation, and storage, you could easily add another $24,000 or much more to that bill.

Today, you can choose from a variety of IP PBXs to improve your business phone system. Many business VoIP providers include the cost of a basic hosted PBX in your bill for a basic plan.

 Nowadays, Hosted PBXs and Virtual PBXs are becoming more popular, especially for small or medium-sized businesses that want to save money on their monthly phone bill. Hosted PBXs are full PBX systems that are managed by your VoIP service provider at their data center, keeping you free of any incurred costs for equipment or constant maintenance. A Virtual PBX is a full PBX system hosted by cloud technology over the Internet. Both of these PBX solutions are extremely affordable, and work just as well as legacy PBXs...for half the cost! Choosing a Hosted PBX or Virtual PBX also helps you save on resources and space! Not to mention that it is much easier (and cheaper!) to let your provider make upgrades and perform maintenance on your PBX as opposed to hiring a technician.

If you feel more comfortable with an actual machine PBX, you can use an IP PBX (digital PBX) software or hardware system that supports VoIP calling. Do keep in mind, however, that these systems can be more costly than hosted or virtual systems (but are still cheaper than the antiquated legacy PBX systems).

What is the Difference Between Business VoIP and a Traditional Phone Service?

VoIP gives users better call quality, more included features, and flexible options.

You may be nervous about switching your business over to a VoIP system. You may feel more comfortable with a PSTN (a traditional telephone service) because they have long-standing experience on their side along with a comfortability that you are used to. However, you should know that improvements in VoIP equipment and Internet connectivity have almost completely eliminated many of the problems that accompanied VoIP during its infancy. You can now get a calling solution that performs just as well (if not better!) than any traditional landline service for a much lower per-month cost.

Not every business may be a candidate for VoIP, but a growing number of small to medium-sized businesses are switching over from their traditional phone service. With a business VoIP plan, customers enjoy:

  • Reduced rates
  • High call quality
  • Improved employee productivity
  • Enterprise features
  • Mobility for remote employees
  • Scalability for future growth

What Do I Need to Know Before Switching to VoIP?

If you're ready to make the switch to a VoIP service, consider the following factors.

There are a few things you should know about VoIP before you switch. For example, a 911 service on VoIP lines works differently than a traditional phone system. 911 operators can't trace 911 calls made on a VoIP line the way they can with a traditional landline number. It is very important that you remember to program your address on your VoIP line through the E911 (Enhanced 911) feature. This way, a physical address will be connected to your phone number. Remember to change your address if you move so that 911 operators can locate you.

You should also ask yourself: is it important to keep my current number? If so, you'll want to be sure that your provider offers number porting. Number porting is a service offered through most VoIP providers (often listed under the plan's features), and it allows you to keep (or "port") your current number over to your new provider. Check with your service provider, as some providers offer this option for free, while others charge a nominal one-time fee.

Also, does your provider offer BYOD? If so, bringing your own phone to your new provider could help you save on equipment costs. Select providers offer this option or even provide you with free phones and ATA adapters.

Before you try to sign up with a business VoIP provider, you should make sure that you have a high-quality high-speed Internet connection. You need to have a good high-speed Internet connection in order to have high-quality calls. It is also important you have a good router in order for successful VoIP implementation. You need a device that is powerful enough to handle however many phones you expect to be connected to your VoIP network. Test your connection with our Speed Test.

You should also be aware that a power loss will result in the loss of a VoIP service. If you don't have a backup source of power, your VoIP phone line won't work. Be sure to get a backup generator or a battery for your Internet connection in case of a power outage.
