VoIP Maryland: Comparing 7 Top Business VoIP Providers in Maryland

VoIP Maryland: Comparing 7 Top Business VoIP Providers in Maryland

Business-class voice-over-IP (VOIP) services are revolutionizing communications. 

As organizations move their communication tools away from traditional phone service providers and premise-based PBX to the cloud, they're unlocking lower overhead costs, spending less on maintenance, and getting new features that can scale to meet explosive business growth. 

For one global organization, Dell, a move to cloud VoIP saved $39.5 million and allowed their employees to begin regularly telecommuting via mobility features.

There are advantages to choosing a local company for Mid-Atlantic organizations and companies in Maryland for your VoIP needs. 

Working with a locally-owned and operated organization can provide access to consulting, support, and maintenance services via local experts and techs, as opposed to third-party contractors hired by a national provider. Fortunately, there are several high-quality options based in Rockville, Bethesda, Silver Spring, and other areas of Maryland.

Not all VoIP providers are created equal. The organizations profiled here don't offer the same specializations; some focus on phone service only for smaller businesses, while others are in the managed IT vertical.

How To Choose VoIP Service Providers: Maryland 

To choose the best VoIP service provider for your Maryland-based business, you'll need to have a concrete system to evaluate vendors. When considering a VoIP service provider, you should ask six vital questions. The answers to these questions will help you make the best decision for your business regarding VoIP service providers in Maryland.


  • What features does your service offer?
    Your business has unique needs. You’ll need to ensure the VoIP service provider you are pursuing offers the features that will meet those needs. Consider features like call waiting, caller ID, virtual extension, and more. 
  • Do you have experience working with clients in our industry?
    Your industry may require different installation, implementation, training, or support needs from other industries. Partnering with a service provider familiar with your industry can save you headaches down the road. 
  • What is your experience working with clients with our capacity?
    What is your business’s call capacity? Does it change seasonally or throughout the week? Ensure your service provider has the back-end infrastructure you need to maintain a high quality for all calls regardless of volume. 
  • What does your customer support system look like?
    No matter how strong the service is, issues are inevitable. When those issues arise, will the service provider be able to support your business and solve the issue quickly? Review testimonials and customer reviews at this point in the evaluation process. 
  • How scalable is your solution? Can you grow with our business?
    How quickly and easily can you add lines and extensions as your business grows? Business expansion always comes with growing pains, but with the right provider, your VoIP solution doesn’t have to be one of those pains. 
  • How reliable is your service?
    We’ve saved the most essential question for last. To succeed, your business needs an uptime level of 99.999 percent. Ask about the levels of redundancy in place with your provider, ensuring a lack of downtime even in the face of power outages or other complications. 


With these questions in mind, let’s examine the top seven VoIP service providers Maryland has to offer. 


1. Chesapeake Telephone Systems

Founded in 1985, Chesapeake Telephone Systems provides Mitel-based VoIP, cloud communication tools, wireless data, and related services to companies in Maryland and the Mid-Atlantic.

“Our 15-year relationship with Chesapeake has really paid off… Thanks for all you’ve done!” -Chesapeake Client

One happy GTB customer in the trucking industry reported being happy with their phone system and the "personal care" they received.

Choosing the Best VoIP Maryland Service Providers For Your Business

If you were looking for a simple, definitive answer to who the best business class VoIP provider in Maryland is, you may be disappointed. "The best" is subjective.

The right local option for a federal contractor who needs compliant VoIP, fiber, and data might not be the same Maryland company as the right choice for a small transportation company that wants repairs to their existing on-site PBX equipment. "The best" depends on your budget, needs, industry, and vision for growth.

Finding the right VoIP service provider is a process that involves research, evaluating multiple options, and picking the company that fits best. Your provider should make VoIP easy and support your business goals. We recommend evaluating potential vendors based on many factors, including the following options:

  • Pricing and quality
  • Redundancy, or Reliability Infrastructure
  • Quality of Service (QoS)
  • Uptime Guarantees
  • Client References
  • Industry Experience and Expertise
  • Compliance and Regulatory Support
  • Support and Support Availability

Atlantech Online Can Help.

As a champion of a locally-owned and operated industry, Atlantech channels our decades of telecommunications knowledge into helping local businesses understand who the right business-class VoIP vendor is for their needs - whether that's our service or another one of the companies listed here.
