The “we bought VoIP phones online — why don’t they work?” problem.
It happens constantly in a market growing as fast as the Triangle. A new office opens near RTP, someone orders a stack of VoIP desk phones online, they arrive, get plugged in — and nothing happens. Here’s what nobody mentioned: a VoIP phone is just a handset. It needs a phone service behind it — a SIP provider, number provisioning, call routing, e911 registration, and a network configured to carry voice cleanly. Buying the phone without the service is like buying a car with no engine and no fuel.
That’s the call we get most often from new Raleigh and Durham businesses. We provision the service, register every 919 or 984 number for emergency calling, tune the network so calls don’t break up — and the same person who sets it up is the person who answers when something goes wrong. For years. That’s the whole pitch.
Running a system the manufacturer walked away from?
If your Triangle office is on any of these, we replace it and keep every number, extension, and voicemail box:
- Avaya IP Office / Aura — Avaya filed Chapter 11 twice (2017, 2023).
- NEC SL2100 / SV9100 — Hardware orders ended December 2024. U.S. support ends March 2026.
- Panasonic KX-NS / KX-TDE — Panasonic exited the market. Dealer support ended March 2025.
- Mitel MiVoice Connect — Mitel filed Chapter 11 in 2023. MiVoice Connect reached end-of-life December 2025.
- Toshiba Strata / IPedge — Toshiba exited phone systems October 2021.
- ShoreTel — Acquired by Mitel, now in the same bankruptcy.
- Nortel — Unsupported since the company collapsed.
You don’t lose your numbers, your auto-attendant, or your voicemail. We migrate it all and turn the old system off only once the new one is proven.
Triangle industries we equip
Technology & Research Triangle Park
RTP’s 7,000 acres and 300+ companies set the pace for the region — and growing startups around it need phone systems that scale without a forklift upgrade. We deliver cloud systems that add seats in minutes, route calls between RTP, downtown Durham, and remote staff, and integrate with the CRMs your team already runs.
Life Sciences & Biotech
The Triangle is the fourth-largest biotech hub in the country. Lab, clinical, and back-office teams need reliable lines, HIPAA-aware call handling, and voicemail-to-email that keeps records clean. We build systems that hold up to audit and don’t drop the call when it matters.
Healthcare & Medical Practices
From Duke and UNC-affiliated practices to independent clinics across Wake and Durham counties, we set up appointment-line routing, after-hours on-call flows, and overflow handling so patients reach a person, not a busy signal.
Construction, Logistics & Trades
The Triangle’s building boom means dispatchers are slammed. We deliver ring groups, cell-phone-as-extension setups, and SMS-to-tech workflows so HVAC, electrical, plumbing, and construction crews never miss a service call — even when the office is drowning.
Cellular data network failover for hurricane remnants and ice storms.
Hurricane remnants that ride up from the coast and stall over the Piedmont. Ice storms that snap limbs and drop power across Wake and Durham counties. A fiber cut on a construction site off I-40. When the internet drops, cloud phones drop with it — unless you have cellular data network failover. We build it into every Triangle deployment. When the primary circuit fails, the system cuts over to 4G/5G automatically. Your 919 or 984 number keeps ringing. Your team keeps answering. You find out from a monitoring alert, not from a customer.
Business texting from your main 919 or 984 number.
Your customers already text. Your main number should too. We enable compliant business texting on the same line your calls run through, so your front desk, your dispatchers, and your sales team can answer texts to your published number — without handing out personal cell numbers. Appointment confirmations, quote follow-ups, “tech is 10 minutes out” — all from the number your customers already know.
