Managed IT, Security & VoIP Outcomes
How We Transform Local SMB Infrastructure
Since 2001, eSmith IT has supported small and mid-sized businesses within 60 miles of Huntersville, NC. Here is how our core infrastructure deployments solve real operational bottlenecks.
Managed 3CX VoIP & SIP Trunking
25+ Allstate Insurance Agencies (Charlotte & NC)
Challenge: Rising per-extension phone bills, rigid multi-year carrier contracts, and dropped calls during storms or ISP outages.
Solution: Migrated agencies to dedicated 3CX cloud PBX systems with unlimited SIP trunking, mobile/desktop softphones, and STIR/SHAKEN caller ID authentication.
Result: 35%–50% average monthly telecom savings with sub-15-minute local engineering support.
Unbreakable Internet & Dual-WAN Failover
Multi-Provider Medical & Urgent Care Clinics (Charlotte Metro)
Challenge: Primary fiber/cable cuts halted EHR/EMR access, credit card terminals, and patient check-in phones for hours at a time.
Solution: Deployed enterprise gateway routers with automatic sub-second 5G cellular failover and isolated HIPAA-compliant VLANs.
Result: Zero clinic downtime during local ISP outages; voice calls and EHR sessions stay active seamlessly.
Managed IT, EDR & M365 Hardening
Lake Norman Law, CPA & Construction Firms (10–50 Staff)
Challenge: Outgrowing break-fix IT support, facing cyber insurance compliance audits, and struggling with slow 24–48 hour ticket responses.
Solution: Implemented flat-rate managed IT support, 24/7 Huntress EDR, Microsoft 365 Conditional Access/MFA enforcement, and immutable cloud backups.
Result: 100% cyber insurance audit pass rate and <15-minute average live engineer response time.
