VoIP Providers & Business Phone Companies in Charleston, WV

Advantage Technology, which also goes by Advantage.Tech, is an independently owned managed service provider and professional services firm headquartered in West Virginia. Its core audience is midmarket organizations. Business phone service is just one part of a wide portfolio that spans managed IT, cybersecurity, compliance, cloud hosting, and infrastructure installed at customer sites. A company that wants its voice platform run by the same people who maintain its network and defenses can find all of those disciplines under one roof.

Voice and Communications Services

The firm groups its telephony work under a heading called Cloud Phone Systems. The offering covers hosted calling, contact center tooling, and connections to the collaboration software that clients already rely on. The listed services are:

• Hosted VoIP and cloud PBX
• SIP trunking for locations that keep on-premises equipment
• Microsoft Teams Phone
• Unified communications delivered as a service (UCaaS)
• Cloud-based contact center platforms
• Phone systems built around healthcare privacy requirements
• VoIP integrations with other business applications
• Moves off legacy lines, including number porting

Telecommunications hardware is also available through the company's product catalog, next to computers, networking gear, servers, and security cameras. Since the firm employs its own structured cabling technicians, it can run the physical wiring a new phone rollout needs in addition to configuring the system itself.

Team and Credentials

A dedicated telecommunications group is overseen by a supervisor and includes an operations administrator along with cabling technicians at a range of experience levels. The engineering department adds a telecom engineer and several network engineers. The company says its staff holds more than 50 certifications, including CCNP Collaboration, Registered Communications Distribution Designer, Mitel IPBX Advanced, and CISSP. Named technology partners include Avaya, Microsoft, Extreme Networks, SonicWall, Dell, Verkada, and Arctic Wolf.

The company reports that it has undergone a SOC 2 audit. Its Trust Center presents continuous monitoring, layered protections, and a compliance program tied to several recognized frameworks, including healthcare privacy rules and federal defense-contractor requirements. Organizations in regulated industries may find that useful when comparing voice providers.

Background and Locations

The business started in 2002 as a single person working from a spare bedroom in West Virginia. Richard S. Wilbur III is the founder, president, and chief executive. Today it reports more than 100 employees, over 800 organizations served across the United States, Europe, and Canada, more than 10,000 completed projects, and a customer retention rate of 95.2 percent.

Offices are in Charleston and Bridgeport, West Virginia, and in Frederick, Maryland. Its main service area is West Virginia, Maryland, and the greater DMV region.

Approach to Clients

The company calls itself engineering-led and emphasizes senior-level support, no shortcuts, and no private equity backing. It presents itself as a single accountable partner rather than a patchwork of vendors. It also publishes articles for organizations thinking about leaving landlines behind, including one on why small businesses are dropping them for VoIP. With voice, networking, cabling, and security skills available together, the firm is a fit for businesses that want communications managed as part of a broader IT strategy.
