VoIP Phone Service for Fairfax, VA

Is your current phone system not keeping up with the demands of your business? Do you find your company is missing calls—or worse yet—sales due to lacking functionality or features? A new VoIP phone system from Computer Services Unlimited may be in order.

An aging analog landline phone system, such as a public switched telephone network (PSTN), can be a major headache for any small business. These traditional, older-style systems are incredibly outdated and lack the versatility required by an ever-changing business landscape. Additionally, with so many organizations moving their workforces to either part-time or full-time remote environments, it pays to have the flexibility of VoIP phone service. You deserve a solution that moves at the same pace your business does.

With our new VoIP solutions in Fairfax, you can rest assured that your business needs will be not only met but far exceeded. Contact us today for a FREE 30-Minute Network Audit and see how our small business phone system can work for your company!

What is VoIP Phone Service?

VoIP (Voice over IP) 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 50.8% of households rely solely on their wireless phones, according to a finding by the US Health Department. The percentage of households that choose only to use a landline is a tiny 6.5%—embracing the future of VoIP isn't a matter of if, but when.

How Can VoIP Phone Service Benefit My Business?

A VoIP phone system enables you to 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. A VoIP phone system grows with your business without the need for costly equipment upgrades.

VoIP offers all the same features you get with a landline, along with many added advanced features that you cannot get with a traditional landline phone. One of the most significant benefits of VoIP is cost savings. 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 service provides the benefits every business requires with useful features, the ability to take on your company’s workload, and low-cost and easy installation.
