You Need Phone Services that Can Keep Up with Today’s Fast-Paced World

Are you tired of dealing with outdated communication systems that are holding back your small business's growth? Traditional phone systems just don't cut it in today's fast-paced digital world. An aging analog landline phone system, such as a public switched telephone network (PSTN), can be a major headache for any business. These traditional, older-style systems are incredibly outdated and lack the versatility required by an ever-changing business landscape.

They come with a range of limitations that can hinder your business's efficiency and productivity. Imagine the frustration of expensive long-distance calls eating into your budget, the struggle to scale your communication infrastructure as your business expands, and the inability to stay connected on the go. These are just a few of the issues faced by businesses relying on traditional phone systems. It's time for a change. It’s time for VoIP.

How Can VoIP Phone Services Benefit My Business?

A VoIP phone system lets you take phone calls when you’re on the go, access customer information quickly, and keep your business moving forward. With optimized technology, your VoIP phone system will never go down because too many calls are being made. This communication technology grows with your business without the need for costly equipment upgrades.

VoIP offers all the same features you get with a landline, like a unique phone number, unlimited calls, and the ability to make and receive calls. You’ll also get the many added advanced features that you cannot get with a traditional landline phone. Some of these features include video conferences, call recording, use of toll-free numbers, and integration with your customer relationship management (CRM) system.

One of the most significant benefits of VoIP is cost savings. As a VoIP provider in the DC metro area, our typical client saves a considerable amount on their phone bill. And if you have multiple offices, make a lot of international calls, or have a heavy call center, the savings can be staggering. Many of our clients have seen drastic per month savings each year just by switching to VoIP.

If you’re not happy with your current phone situation because you have outgrown it or need new features, then give us a call today. Let Computer Services Unlimited’s VoIP phone service in the DC metro area provide the benefits every business requires with valuable features, the ability to take on your company’s workload, and low-cost and easy installation.

With better tracking, you can help your business grow by having accurate customer information and valuable insights into your customers' needs to serve them better and increase your profits.

Frequently Asked Questions about VoIP

You likely have some questions about business VoIP services, and we’re going to answer some of the ones we most commonly hear. If you need more information about VoIP phone services, call quality, or how it works, please feel free to get in touch with us! For additional information, please read our blog on the three big steps to finding the right VoIP phone service, or you can contact us to receive a FREE 30-Minute Network Audit, where we'll determine what solutions are best for your business.


VoIP (Voice over Internet Protocol) phone service utilizes an IP network instead of a traditional phone network. VoIP systems use software, hardware, and a high-speed internet connection to make and receive phone calls. You can call from anywhere using a specialized desk phone, laptop, or even a smartphone with a mobile app.

In many ways, VoIP is the future of phone service in America. More and more phone providers are looking to move away from the expensive cycle of replacing, repairing, and updating older analog systems because the customer base that uses them has been shrinking for years.

It's interesting to note that 72.6% of households rely solely on their wireless phones, according to a 2022 finding by the U.S. Health Department. The percentage of households that choose only to use a landline is a tiny 2.1%—embracing the future of VoIP isn't a matter of if but when.

You can learn even more about VoIP phone services in the DC metro area and how to select a provider by reading Buying VoIP.


VoIP phone calls come through your internet connection rather than using a traditional landline or mobile network to make calls. VoIP converts your voice into a digital signal, compresses it, and sends it over the internet to the recipient.

Choosing CSU is a no-brainer for businesses looking for VoIP phone services in the DC metro area. We’ll not only set up the technology needed to make this phone plan work for you, but we’ll also train your staff to get the most use from the system. Plus, we’ll be there for you whenever you need us for troubleshooting, updates, and more.


The quality of calls is outstanding with VoIP phone systems. With traditional and mobile phones, your voice is transmitted in standard definition. This level of quality means that your voice can be affected by noisy surroundings, poor coverage areas, and dropped calls. In contrast, VoIP transmits your voice in high definition, so calls are clear and crisp, no matter if you’re calling a person in the local area or using long-distance calling.


You will need access to the internet to use a VoIP phone system and the specialized software or hardware to make a call. The hardware to make phone calls includes specialized desktop phones, laptops, and mobile devices. Like specific mobile or desktop apps, the software allows you to take your VoIP services anywhere in the DC metro area.


Yes, in fact, VoIP is excellent whether your workforce meets in an office every day or through the internet. Employees can use apps on their mobile devices or desktops to call, text, email, video conference, and even fax their customers and co-workers. So, there’s no longer a need to be in the office to be productive. Whether you’re out meeting with clients or want to hire an exceptional staff member in another state, VoIP is the solution for you!

Additionally, if there’s anything that COVID-19 has taught business owners, it’s that working outside the confines of a building is essential to survive. Plus, more businesses are offering work-from-home as an employee benefit, so to stay competitive in today’s job market, offering remote work can be highly beneficial to your company.

Not only can VoIP accommodate your remote workforce and save you money while doing so, but you’ll also save money in other ways too. By having people work from their homes and not in your building, you’ll save on energy costs. With fewer people operating your office machines, lighting, and heating, you’ll find cost savings in that aspect, too.

And if you’re considering allowing your employees to go fully remote, you’ll need cloud computing support and more robust network security. When you choose a VoIP provider in the DC metro area that can also provide these services, like Computer Services Unlimited, you’ll get reliable, friendly IT services for a flat rate. Using one provider makes it even easier to get the support you need when you need it.


Skype and Zoom are programs that use VoIP technology for video and phone calls. However, using only Skype or Zoom for VoIP doesn’t give you all the support, features, and services that choosing a VoIP provider in the DC metro area can provide. For example, we can also help you with things like data back-up and recovery, co-managed IT support, and remaining compliant with federal and industry standards.


Since a VoIP system can go anywhere you go, you’ll never miss an opportunity to network or make a sale as a business. Let a VoIP system grow with your business, and only spend what you need when you need it.


VoIP phone systems are reliable and valuable because you can take them anywhere you have a mobile device or laptop and access to high-speed internet. You don’t have to worry about dropped calls or busy signals, either. The only downside is that if there is an internet outage at your location, you won’t be able to make or receive calls. However, there are alternative solutions to use for backup in these cases. However, these instances of down internet service don’t happen very often, and your smartphones can still be used during these times.

Didn't find the answer to your specific question about VoIP above? Are you ready to get started with crystal-clear call quality, reliable phone service, and advanced features you can’t get from traditional landlines? Either way, get in touch with us today, and our team will be happy to help!
