Yes. Microsoft Teams Phone System with Calling Plans or Direct Routing can replace traditional PBX systems. EPC Group has migrated thousands of users from legacy phone systems to Teams Phone, including complex multi-site deployments with E911 compliance.
Yes, when properly configured. Microsoft Teams can be HIPAA-compliant with appropriate DLP policies, sensitivity labels, guest access controls, and audit logging. EPC Group deploys Teams for healthcare organizations with full HIPAA safeguards and BAA compliance.
EPC Group implements Teams governance frameworks covering team creation policies, naming conventions, lifecycle management, external sharing controls, guest access policies, retention settings, and Copilot governance — preventing the sprawl that plagues ungoverned Teams deployments.

Microsoft Solutions Partner status (six designations: Data & AI, Modern Work, Infrastructure, Security, Digital & App Innovation, Business Applications) replaced the legacy Microsoft Gold Partner program in 2022. EPC Group held Gold Partner status from 2003 to 2022 (the oldest continuous Gold Partner in North America) and currently holds all six Solutions Partner designations; a credentialing footprint shared by fewer than 50 firms globally and typically used by Microsoft field teams as a vetting gate for enterprise Customer 0 nominations and named-account engagements.
EPC Group 29-year Microsoft consulting heritage matters specifically because Microsoft platform decisions today are layered on top of 25 years of architectural choices: Active Directory schema decisions from 2005 affect Microsoft Entra ID Conditional Access policy design in 2026; SharePoint 2003 information architecture decisions affect Copilot grounding quality in 2026. The firms that can navigate that depth (fewer than a dozen Microsoft Solutions Partners in North America) have a structural advantage on enterprise Microsoft migrations.

EPC Group delivers Business Pbx System as a core practice within the Microsoft consulting portfolio. Engagements are led by senior architects with hands-on Fortune 500 delivery experience and a bench of hundreds of Microsoft-certified consultants spanning SharePoint, Microsoft 365, Power BI, Azure, Microsoft Copilot, and Microsoft Purview.
Every Business Pbx System engagement is engineered for the regulatory and operational environment it serves. Healthcare deployments carry HIPAA controls from day one; financial services deployments meet SOC 2 and FINRA retention requirements; government deployments map to FedRAMP and CMMC controls with audit-ready evidence.
Every engagement is led and staffed by 15 to 20 year veterans. No rotating juniors learning on your tenant. The bench includes hundreds of Microsoft-certified consultants who have shipped real production environments for Fortune 500 customers across SharePoint, Microsoft 365, Power BI, Azure, and Microsoft Copilot.
Six-phase methodology applied to every engagement, compressed for fixed-fee accelerators and extended for full programs.
For hospitals, payors, and pharmaceutical companies, EPC Group enforces HIPAA, business associate agreements, and Microsoft Purview sensitivity labels for protected health information. Epic and Cerner integration patterns are part of our regulated-industry library, alongside 21 CFR Part 11 e-signature controls for clinical trials and validated SharePoint document workflows for life-sciences manufacturing.
For federal agencies and CMMC-regulated suppliers, EPC Group delivers FedRAMP Moderate and High posture, GCC and GCC High tenants, CUI handling, and ITAR-controlled data segregation. Errin O'Connor (CEO and founder) is a contributor to the FedRAMP framework; that direct authorship shows up in how we architect Conditional Access for government endpoints.
Zero governance audit failures across 11,000-plus enterprise engagements. HIPAA, SOC 2, FINRA, FedRAMP, and CMMC controls are engineered into the tenant on day one with audit-ready evidence. The regulated-industry posture is the baseline, not an upgrade tier.
Three engagement models cover most enterprise needs. Most clients start with a fixed-fee accelerator and grow into a full program or a managed-services retainer.
