VoIP Providers & Business Phone Companies in South Burlington, VT

Network Performance Inc., which operates as NPI Technology Management, is an integrated IT services firm based in South Burlington, Vermont. It does not sell phone service in isolation. Instead, it folds business voice into a wider managed technology program, which suits organizations that want a single partner responsible for their network, security, cloud systems and telephony.

Its voice offering, Canopy Voice, belongs to a family of Canopy-branded managed services and is presented as the company's solution for staff communication and teamwork.

Services and offerings

Buyers comparing phone providers will find that NPI places voice alongside a full set of managed IT plans, so calling infrastructure is supported by the same team that looks after the underlying network. The current lineup includes:

• Canopy Voice for business calling and collaboration
• Canopy Managed Network for ongoing network oversight
• Canopy Select for productivity-focused support
• Canopy Workforce Defense for security
• Canopy Managed Cloud for scalable hosted systems
• Canopy Backup and Recovery for data protection
• Strategic planning and technology budgeting
• Systems, security and collaboration tools for remote teams

NPI's approach centers on planning ahead rather than reacting to breakdowns. Clients describe a structured process in which equipment follows a known replacement schedule, systems are watched around the clock, and multi-year outlooks help finance leaders build technology budgets.

Staff meet with clients periodically to review current status and upcoming needs, and they coordinate with third-party vendors so office managers can hand off those relationships. Help is available in person at client sites as well as remotely, and the firm takes on infrastructure projects that start with detailed conversations about what the customer wants to achieve.

The organizations quoted on NPI's site span a wide range of Vermont sectors, which gives a sense of the environments its team is used to supporting:

• Senior living, including a life plan community
• Government relations and lobbying
• Ecommerce and retail
• Dental and medical practices
• Biotechnology
• Textile manufacturing
• Accounting and professional services

The company reports decades of experience in business IT, and one accounting client notes a working relationship stretching back roughly 25 years. NPI is led by CEO Eric Hart, whom clients mention as personally reachable when his input is needed. The firm describes its philosophy as the "Vermont Way," emphasizing long-term relationships grounded in trust, teamwork and fresh thinking. Internally, it practices open-book management, supports staff certifications and ongoing training, and contributes donated technology projects to local nonprofits.

For businesses evaluating VoIP vendors, NPI is best viewed as a managed services partner that includes voice rather than a standalone carrier. Organizations that value having phones, network performance, cybersecurity and backup handled by one accountable Vermont team may find that model attractive, while those seeking specific calling features should discuss Canopy Voice details directly with the company during evaluation.

Tech Group, LLC, which presents itself online as The Tech Group, is a technology services firm based in South Burlington, Vermont. It has supported organizations around the state since 1992. The company is best known as a managed service provider, but it also lists VoIP phone solutions among its core offerings.

That makes it worth considering for businesses that want their phone system and their wider IT support handled by one partner. The firm says it now belongs to the New Charter Technologies family of companies.

For buyers comparing business phone companies, the main point is that voice service here is part of a broader IT relationship rather than a standalone telecom product. The pages reviewed for this listing name VoIP as a service line. They do not describe specific phone platforms, handsets or calling features. Prospective clients should ask the team directly about system choices, number porting and how phone issues are handled by support staff.
