Voice over IP (VoIP) is such a hot topic because it has become the new default backbone for business communications.
Three years ago, Network World predicted the rapidly approaching end of public switched telephone networks (PSTN), writing, "Replacement of the PSTN with a global VoIP-only network delivering service provider wired voice and wireless voice is not a question of if, but when."
That was the same year that the Harvard Business Review suggested it was finally "the end of the line for the analog phone networks" as the FCC began conducting trials on converting entire communities from PSTN to VoIP as quickly as possible.
The end of plain old telephone service
Part of this large-scale digital transformation in telecom involves the abandonment of the traditional phone lines that carried the nation's phone conversations for most of the past century. Copper land lines are now fading into history, either replaced by optical fiber as they breakdown or simply no longer serviced.
This summer, Illinois joined 19 other states that have authorized the end to copper land line servicing so that telecom companies can devote resources to developing VoIP and other future communications technology.
Meanwhile, the National Regulatory Research Institute (NRRI) reported that 41 states have now either reduced or eliminated their oversight of wired telecom. VoIP converts voice, video and data into digital packets that can travel easily across fiber, cellular networks or Wi-Fi.
That future-proofing flexibility explains why VoIP is now No. 1 telephone service choice by US businesses, in a report on business VoIP usage by Software Advice. Approximately 36% of business are using VoIP today.
In second place, an estimated 24% of businesses continue to rely on PSTN, aka plain old telephone service (POTS), even though it can't handle next-gen data and video. Primary rate interface (PRI) comes in third place, used by 11% of businesses, mostly large enterprises using a mix of PBX, ISDN circuits and T1 lines.
Virtual PBX phone systems
The fourth category of telephony technologies is the most recent. Around 8% of businesses are using cellular networks as their primary business line. That number is likely to soar in the future as the workplace transforms into a digital, mobile-first world of solopreneurs and online businesses.
This conclusion is backed up by survey responses given by business owners on why they upgraded their phone systems. The top reason for switching to VoIP for 29% of respondents was that they needed an easy way to forward calls to their mobile phones.
A close second at 25% was a flexible voicemail system that was simple to access on the road. In third place at 21% was a phone system that simplified interoperability with their existing mobile phones. The top three answers, representing a combined 75% of the survey responses, indicate that the future of business is mobile.
In the years ahead, phone service providers will invest heavily in technologies built on VoIP, including Voice over LTE (VoLTE) and HDVoice. Look for a wave of mergers and acquisitions in 2018 as the turbulent market sifts out the winners from the losers. Telecom industry analysts at Entrepreneur to Exit suggested, "Amid considerable M&A activity across the IT channel, one particular hotspot involves IP telephony."
As coverage areas and feature sets won't work as differentiators anymore, phone service providers are competing on factors such as the quality of their voice UX and wider interoperability.
High quality voice UX
For companies that have not yet implemented a VoIP system, they cite concern over poor sound quality. VoIP is often associated with the early years of free and low-cost providers like Google Voice and Skype. In the 20 years since VoIP was introduced, service providers have been working intensely with sound engineers to dial up VoIP's Quality of Service (QoS).
The sound quality or Voice UX of VoIP systems are impacted most by the bandwidth available and stress on the network. For smaller companies operating near their network capacity, VoIP is only an option in the cloud or over their cellular services.
The biggest advances in this area have been handled internally by the big four cell service providers: Verizon, AT&T, T-Mobile and Sprint. Each as their own versions of VoLTE and HDVoice. These are VoIP options with first-class voice UX delivered over cellular networks. They rely on the processing speeds of massive server farms owned by the service providers and the most advanced software for improving sound quality.
5G and the next generation
In the year ahead, 5G will come online in more locations. It is projected to stream voice, video and data 10 times faster than 4G. A report on 5G by IT Toolbox concluded, "5G will also improve the quality of VoIP calls by notably reducing or even eliminating jitteriness, data transfer losses and the much-dreaded dropped call."
While there have been great strides in voice UX, interoperability still needs attention. Many of the central functions that used to be performed by software on desktops are now handled by smartphones, including email, meeting notes, project planning, data analysis, CRM updating, task coordination and administrative work. In the year ahead, VoIP and cell service providers will devote more resources to making sure that mobile communications integrate more naturally into back office functions.
A good example is the spread of "Click to call" buttons, driven by the dominance of smartphones over PCs as the primary way people access the web. Research by Google revealed that 70% of mobile users expect businesses to enable a "Click to call" functionality on their main websites. Interoperability between the web, phone systems and back office software will be the new frontier in VoIP development.
The new last mile
The new last mile in telecom isn't hardwired into a fixed structure but follows the user wherever they are. As the workforce is increasingly mobile and remote, empowering mobility in the field becomes a key differentiator in business phone service. Mobile-first, software-based phone systems are designed to be managed and deployed across your mobile phone infastructure.
The WEF estimated that the digitalization of telecom will be worth $2 trillion in operating profit by 2025. Part of that value will come from the tranformation of clunky desk phones, complex wiring and aging servers to virtual phone systems that live in the cloud and intutively adapt to network capacity to deliver the highest quality voice experience possible.
As voice is better supported by mobility and smart tech, a new user experience is emerging. AI is transforming telecom, from more resilient networks to better call quality and advanced analytics.

Put Your Home on Virtual Lockdown
Chocolate and peanut butter, eBay and your significant other's credit card, internet surfing and a virtual private network (VPN); What do these things have in common? They're good on their own but great when put together. And here's another great pairing: VPNs and your router. Before your eyes glaze over, give the idea a chance, because combining these two things isn't only easy, it makes both significantly better.
Why Install a VPN on Your Router?
If you're a typical internet user, then you should already be using a VPN, at least in its web service incarnation. That is, unless you like having your web habits scrutinized and your data open to anyone because it's not encrypted. This means downloading a free client or paying a small monthly dollar amount for a premium, more full-featured client from makers such as NordVPN. In either case, you'll pay for each client application individually, and you'll download one to every device you use to trundle through the interweb jungle.
That's an OK approach if you've got one or two devices, but what about a typical family who might have several notebooks, desktops, tablets, phones, TVs, and other smart home devices connected to a network? That's not only a lot of devices, that's a lot of VPN clients with fees that can add up if you're using one for every device. But what if you could just install a single VPN client directly on your router? That's one download and one installation and configuration session. And after that, every device on your side of the router will use the VPN when it connects to the outside world. If that's not a better-together scenario, I don't know what is. You're probably saving money and you don't have to worry if the kids are remembering to activate the VPN before they connect, because the router keeps it active all of the time.
All of the routers featured here support the ability to install a VPN client, though they might do it in only one of the different ways we'll describe below. Most commonly, they will support the OpenVPN standard, meaning you can configure a VPN with any provider that supports that standard. Alternatively, the featured models may be compatible with the DD-WRT or Tomato router operating systems (more on that below). Once you've upgraded your router to one of these platforms, you'll be able to configure a VPN on it.
Key VPN Router Considerations
While the benefits of having a VPN on your router are clear, the path to choosing one, ironically, starts with considering the downsides, of which there are basically two. The first is that setting up a VPN client on your router isn't quite as simple as doing it on your average user-style device, though it's by no means neurosurgery. The second downside is probably the more important one and that's bandwidth considerations.
By forcing your connection out through a single VPN tunnel, you're effectively limiting your internet speed to whatever throughput that tunnel can provide. This means you really, really need to pay attention to the speed tests of our VPN reviews because you want the fastest one available in your area. You also want to test such services yourself on your own devices and across your own internet connection before committing to one, as these numbers can be highly dependent on geography.
If you're willing to tackle some complexity, then you've got more options when it comes to bandwidth optimization. Let's say you're paying for a fat, 1 gigabits per second (Gbps) internet connection from Verizon Fios, our Editors' Choice-winning internet service provider (ISP). Let's also say you manage to install a second router next to your hyper-proprietary Verizon Fios router and install a VPN client on that. But your VPN provider can only support 200 megabits per second (Mbps) between you and its servers.
What this means is: You're now paying for 800 Mbps that you're no longer using since you're pointing every internet-capable device in your home at that one VPN tunnel. In this scenario, you'd still save money by installing two or maybe even three VPN clients on your router, each pointing to a different VPN provider with each of those providing their own +/-200 Mbps connection. Now you point different devices at different VPNs so everyone gets a fair slice of the Verizon Fios bandwidth pie. Your son's gaming PC, your husband's work notebook, and the Smart TV share VPN tunnel A, while your notebook, your daughter's iPad Pro, and your Voice-over-IP (VoIP) phone system share Tunnel B. Like that. You'd now be using most of your Verizon Fios bandwidth, and you'd still be saving money over installing and paying for a separate VPN client for every device.
If you're router-savvy, then you can do this with source routing. But whether or not your particular router supports source routing is something you'll need to find out from the documentation. More advanced routing OSes, like DD-WRT, support source routing either directly or via policy routing (see below), but again, this isn't for beginners.
Given all of that complexity, most consumers will simply opt for the fastest VPN connection they can get and split that up among their home devices since it will be a fairly rare day that all devices will be trying to connect simultaneously. If you want to measure your internet speed both with and without a VPN connection, then use the PCMag Speed Test.
How to Choose a VPN Router
Once you've determined that running your VPN from the router really is better for you, there comes the question of choosing one. Here's where it might get a little complex...or not, if you're a little bit fortunate. That's because there are several ways to get a router that's VPN-capable. The most direct way is to simply buy one from your VPN provider.
Several personal VPN service providers are now offering routers that come preconfigured with one of their clients, including market leaders such as NordVPN and TorGuard VPN. Not only do you get a client ready and working, you also often get a fairly wide selection of routers. TorGuard, for example, offers its client on routers from Asus, GLI, Linksys, and Netgear, among others. Downside? Lack of flexibility in configuration and, potentially, price depending on how the service provider decides to charge for a client housed on a router over one confined to a single device. For those looking to keep more control, however, you'll need to delve into DIY (do-it-yourself).
When going the DIY route, your first step should be to check the features table above this article as well as your current router's documentation. You're looking to see whether it's VPN-compatible, whether it's specifically compatible with any particular VPN vendor, or whether it's compatible with OpenVPN.
OpenVPN isn't just a standalone VPN product, it's also an open-source VPN platform that's become something of a standard in the VPN world. Providers often support their own platform as well as OpenVPN simply to give their customers, especially their small business customers, some choice when it comes to client software since downloading the OpenVPN client is free. Remember, your router is essentially a little computer with its own proprietary OS embedded in its firmware. What that OS supports is up to each router manufacturer (i.e., Asus, Linksys, and Netgear, to name a few). If your router supports OpenVPN, then it's compatible with a large swath (though not all) VPN service providers. Some will provide documentation on configuring an OpenVPN client with their service, but some won't.
Your best bet is to start with the VPN provider's documentation, then check the router manufacturer's documentation, and then do an internet search to see if the process is described in any third-party support forums. Move on to another, more router-friendly VPN provider if all of those steps fail. Though, if you're determined to go the DIY router, then that's not your only path.
The Pre-Flashed Router Option
If your router's installed OS can't help you, then it's time to think about another OS. This could mean buying another router or it could mean upgrading the one you have an alternate router OS, typically either DD-WRT or Tomato. These are two open-source, alternate router environments that you can download and install on your router, provided your router is compatible and your router maker allows this. If it's allowed, then either of these downloads will effectively replace your current router's OS (and full disclosure: will most likely also replace your warranty with that router manufacturer).
Again, while this isn't proverbial rocket science, it's not for the technically faint of heart, either. However, the benefits are significant. Both DD-WRT and Tomato are ongoing projects that are constantly being improved, which means you're getting a number of features that your native router OS probably doesn't have. One of these features is full support for OpenVPN, which means that, as soon as you've flash-converted your router to either DD-WRT or Tomato, you'll be compatible with a large number of VPN providers.
If all this talk of cracking your router's brain open is making your techno-knees a little weak, don't despair because where there's an even mildly thorny technology problem, there's usually a happy geek waiting to solve it for you, provided you pay her enough. That's the same thing here, though in this instance, that geek will be selling what's called "pre-flashed routers."
Pre-flashed routers are exactly what the name implies: a name-brand router sold to you by a third party that has taken on the headache of flashing the router to a new OS, usually DD-WRT. You're basically getting the same thing as you would get if you bought a router directly from NordVPN or TorGuard. However, some pre-flash vendors offer not only an upgrade to the router's OS, they also offer to simply sell you a router with a proprietary VPN client pre-installed, such as ExpressVPN.
In some cases, they even replace the support and warranty from the original router maker if their customization machinations were enough to void it. A quick internet search will provide a list of such vendors and, once you choose the router you want, they'll deliver it to your door with the requested OS, custom configuration, or VPN client pre-installed and ready to go (though, again, at something of a premium over buying the router direct from the manufacturer and doing the upgrade yourself).
That can be well worth it, however, since you're getting a lot more here than just the ability to run a VPN on your router. DD-WRT is probably faster than a standard router OS, gets regular updates that are probably a little more regular than a standard router OS, and offers a plethora of additional features that alpha-geeks will love because it lets them up their security and customize their networks. Such features include the policy-based routing I mentioned earlier as well as things such as advanced Quality of Service (QoS), real-time monitoring from anywhere, Dynamic DNS (DDNS), and more.
VPN Business Benefits
If some of the features just listed sound a little like things the IT person at work would like, then that's because they are. And it also means that flashing your router to DD-WRT or another third-party router OS might get your business some additional benefits. Exactly what those benefits are depends on your business and what it needs from its network, though "more speed" and "more options" is always a good thing.
One specific thing that might improve is the way your business can use its VPNs. While providing a VPN service to every user can have benefits for small businesses, midsize and larger-sized businesses will want to set up their own VPN gateways rather than hiring them out to a third party, such as NordVPN or Private Internet Access VPN for each individual user. That's not only for security and compliance reasons, but also for performance since your IT staffers will have better control of your users' internet experience this way.
But another option important to businesses will be the ability to connect different geographic sites using VPNs. In the misty days of yore, if your business had a headquarters (HQ) in New York and a field office in Maryland, then you'd have to pay the phone company to let you share some kind of wire that ran between those locations; this was usually expensive. With the internet, that business took a fast nosedive until companies realized that their data was wide open to capture while it traversed the web. Perfect solution: site-to-site VPNs—all the low cost of the internet with all of the privacy of high-grade encryption.
Site-to-site VPNs are essentially VPNs that "tunnel" through the web using encryption as the tunnel's walls. They're generally permanent rather than session-based, and remain constantly open between two static routers, essentially putting those two routers and everything behind them on the same network (in the case of our example, one at HQ in New York and one at the field office in Maryland). You still save big bucks over the old-style telecommunications solution, but your data is safe and encrypted in its cozy VPN tunnel. This is the same technology NordVPN uses to connect you to its servers via that little web client you downloaded; it's just being established between two routers for the purpose of shuttling traffic between them. By flashing your routers to DD-WRT, you're guaranteed this ability. However, that's not the only way to get it.
Many routers, even consumer-grade routers, can manage a site-to-site VPN either by using their own VPN client or using OpenVPN. The reason so many consumer-grade routers have this capability is because of telecommuting. Many companies require telecommuters to connect to corporate servers only through a VPN, so having a sub-$100 Linksys home router support it is much more attractive for consumers than forcing them to use a router provided by their IT department. And it's more attractive to the business because that IT router could have cost the business upwards of $600 or more—much more when you factor in man-hours spent on configuration, deployment, and maintenance.
The Purpose-Built, Business-Grade Router
But, while DIY or pre-flashed DD-WRT routers can have benefits for even small businesses, you'd be remiss if you didn't first investigate the VPN routing options available specifically for business and IT customers. All of the routers and VPN services I've mentioned here are primarily aimed at a consumer audience, with spillover into the small business and startup markets. However, more established small businesses and larger organizations will want to investigate routers aimed specifically at them, such as the Linksys LRT224 Dual WAN Gigabit VPN Router.
Boxes like this come with the ability to run multiple VPN technologies simultaneously, and have user interfaces (UIs) designed to let IT managers use them as VPN gateways to allow multiple outside connections for all your telecommuters and roaming workers. They also have a host of other IT features, such as anywhere monitoring and security capabilities like distributed denial of service (DDOS) protection.
