What is Enterprise VoIP?

Enterprise VoIP is business VoIP service designed to meet the specific needs of large enterprises and companies.

Unlike traditional legacy phone systems, enterprise VoIP also has the added advantage of being highly scalable. Businesses can easily and quickly adjust their VoIP service and add or remove lines based on their changing communication needs. No need to go through the long and often complicated process associated with traditional phone services.

Furthermore, the deployment of enterprise VoIP phone systems in organizations can be customized to the address their unique needs. Businesses have the option to deploy a fully-managed cloud phone system, gain complete control via an on-premise system, or enjoy the best of both worlds with a hybrid solution.

But no matter which type of deployment is chosen, enterprise VoIP clearly provide solutions that go far beyond what traditional telephone systems can offer. These enterprise VoIP solutions excel over PSTN and POTS services in regards to functionality, features, and more. Plus, an enterprise VoIP solution may even offer additional security measures to help keep your calls safe.

How Do I Compare Enterprise VoIP Providers?

Choose an enterprise VoIP provider that meets your business requirements and current internet capabilities.

Enterprise VoIP solutions bring a vast number of benefits to organizations. But before you make the transition, it’s vital that you are armed with the right information first when shopping for enterprise VoIP phone systems. Below are some tips to help you find and compare enterprise VoIP providers:

1. Consider your current budget

Although cost shouldn’t be the deciding factor when quality is required, it’s also crucial to take it into consideration when switching to enterprise VoIP. You’re going to have to factor in startup costs, such as upgrading from ordinary handsets to IP phones, modems or routers. Also bear in mind that some providers may charge you if you want to keep your number, although number porting is free through most services.

2. Assess your current bandwidth capabilities

As an enterprise, you’ll want to be sure that you have a sufficient amount of bandwidth to handle all of your calling activities. You’ll also want to ensure that you have a Quality of Service (QoS) router in place, too, so that your calling activities can take bandwidth preference over other bandwidth competitors on your network.

One of the more common issues VoIP customers have trouble with is the call quality. Oftentimes, consumers are tempted to blame their VoIP provider when it comes to poor call quality and connections. However, more often than not the problem lies with your current internet connection as opposed to your provider. Having a stable and capable internet connection is crucial to your company or enterprise being VoIP-ready. Consult our VoIP speed test when considering how many concurrent calls your enterprise will be making at the same time and scale up accordingly:


Number of concurrent calls

Min. required bandwidth

Recommended bandwidth


100 Kbps up and down

3 Mbps up and down


300 Kbps up and down

3 Mbps up and down


500 Kbps up and down

5 Mbps up and down


1 Mbps up and down

5-10 Mbps up and down


You can also get recommendations from VoIP providers you are considering as to how much bandwidth you will need for quality calls. Additionally, there are a number of steps you can take to ensure that your current internet connection is VoIP capable:

  • Run an internet speed test to find out your current upload and download speed
  • Note down all of the competitors for your bandwidth (ie. devices or hardware using your connection)
  • Ensure all of your equipment is updated to the latest software
  • Check for loose wires and connections

3. Read reviews and compare providers

One of the best ways to find out which provider offers the best service to users like you is by reading reviews. VoipReview compiles reviews of the best VoIP providers so you can see how service providers rate on sound quality, price, customer service, features, and reliability. You can easily view how providers rate over time and read personal accounts of users who are either pleased or disappointed with the service. That way you can make an informed decision about which provider can best fit your business requirements.

What is the Difference Between Enterprise VoIP and Other VoIP Types?

There are a few different types of VoIP:


Like other forms of VoIP, business VoIP uses packet-switched telephony to route calls over the Internet instead of through copper lines used by the traditional Public Switched Telephone Network (PSTN). Unlike enterprise VoIP that is made for large and established enterprises, business VoIP services are catered towards small to medium-sized businesses. They incorporate a selection features SMBs need for its daily operations, including audio and video conferencing, virtual numbers, auto attendant, call forwarding, as well as text messaging and chat.

Hosted VoIP, meanwhile, refers to VoIP services that are hosted on the provider’s data centers, which are fully managed and maintained by the provider as well. Most enterprise VoIP solutions nowadays are hosted, instead of being housed onsite. Hosted VoIP is advantageous to many businesses because the responsibility for maintaining, upgrading, and securing the systems are with the provider, allowing companies to focus more on their core business.

Cloud Private Branch Exchange (PBX), also called hosted PBX and IP PBX, refers to the telephone exchange system delivered and managed through the internet by a third-party service provider. Cloud PBX systems provide businesses PBX capabilities but without requiring them to purchase, store, and manage complicated and bulky equipment on-site like traditional PBX systems.

Session Initiation Protocol (SIP) Trunking is a method of delivering business communications (including calls and video and web conferencing) over the internet instead of traditional phone lines.This solution is ideal for larger businesses with an IP PBX in place as it enables them to pay for fewer lines.
