This Hillside-based medical billing company had been running an on-site PBX for years. One day, they discovered their system had been compromised by hackers who used it to make thousands of dollars in illegal international calls.
The damage: over $16,000 in fraudulent charges on a single bill.
How it happened:
| Incident Type: | PBX compromise / toll fraud |
| Fraudulent Charges: | $16,000+ |

When COVID-19 forced offices to close, this medical billing company needed to transition 100+ employees to remote work immediately. Their business—processing claims for healthcare providers—couldn't stop.
VoipPlus reprogrammed their phones and PBX to enable full work-from-home capability. Employees could use softphones or take their desk phones home—calls routed exactly as they did in the office.

"After the fraud incident, we needed a provider we could trust. VoipPlus not only secured our system and saved us 30% on our phone bill, but they've been there for us through six years of growth. When COVID hit, they had our team working from home within days. We've sent them every medical practice that asks who we use for phones."
Over the years, this customer has referred multiple doctor's offices and medical clinics to VoipPlus. When healthcare providers ask who handles their phones, they don't hesitate to share our name.
That kind of trust is earned over years of reliable service, responsive support, and being there when it matters most.
