Business Phone Systems
for the Crossroads of America
Indianapolis sits within a day’s drive of half the U.S. population — which is why logistics, healthcare, and life sciences have all made it home. We install phone systems that work as reliably as the city’s infrastructure, with support that answers faster than the traffic clears on I-465 at 5pm.
AT&T Copper Retirement — Indiana: 56 Wire Centers, June 2026
AT&T grandfathered 56 Indiana wire centers on October 15, 2025 — including facilities serving Indianapolis, Carmel, Fishers, and Greenwood. No new copper orders or changes accepted. Full decommissioning begins June 2026 with only 90 days notice. If your 317 or 463 business line is on AT&T copper, we migrate it to SIP trunking as part of your installation — same number, no interruption.
Hoosier Businesses Run Hard — Your Phone System Needs to Keep Up
There’s a reason Indy calls itself the Crossroads of America — it’s not just the interstates. Indianapolis has built one of the most impressive mid-size city business ecosystems in the country, anchored by Eli Lilly’s global pharmaceutical headquarters and the $13 billion in new manufacturing capacity they’ve committed to in Boone County, IU Health and the broader healthcare system that employs nearly 20% of the regional workforce, and a logistics and distribution infrastructure that takes advantage of the fact that 80% of the U.S. population is within 700 miles.
We’ve installed phone systems for Indianapolis businesses from Mass Ave to Meridian Hills, from the Broad Ripple commercial corridor to the tech companies in the Salesforce Tower footprint in downtown, from distribution operations along I-70 to medical practices in the Castleton corridor. The 317 market has a mix of legacy systems that’s common to the Midwest mid-market: NEC SL2100 systems installed when Peyton Manning was still throwing touchdowns at Lucas Oil, Avaya IP Office in the professional services firms that serve the Lilly ecosystem, and Panasonic KX-NS in the dental offices and medical practices throughout Hamilton County.
A Local 317 Number — or Text-Enable the One You Already Have
We provision new Indianapolis business numbers in 317 (primary Indianapolis area code) and 463 (the overlay added in 2016 as 317 was exhausted), or we port your existing number at no service gap. We also text-enable your current 317 or 463 business line — so when clients text your main number, the message arrives in a shared desktop inbox your whole team can see and respond from. Outbound texts show your business number. Personal cells stay out of business communication entirely. Business texting details →
⚠️ Legacy Systems We Replace Regularly in the Indianapolis Metro
- NEC SL2100 / SV9100 — Heavy penetration in Indianapolis SMB market. NEC exited hardware sales Dec 31, 2024. SV9100 manufacturer support ends March 2026.
- Avaya IP Office — Common in professional services and healthcare-adjacent businesses. Avaya’s 2023 bankruptcy contracted the Indiana dealer network.
- Panasonic KX-NS — Widespread in Hamilton County medical offices and dental practices. All dealer support ended March 2025.
- Mitel MiVoice — Present in Indianapolis hospitality and convention-adjacent businesses. Mitel filed Chapter 11 in 2023.
The combination of the Lilly ecosystem and the healthcare-heavy economy means Indianapolis has a higher-than-average density of professional business environments where a phone system failure is genuinely expensive — not just inconvenient.
“We’re a specialty medical practice in Carmel — 18 staff, two physicians. We’re on a national VoIP platform. During a tornado watch last spring, we lost internet for four hours. Our phones went completely dark. Patients were calling and getting nothing — not even a voicemail. We have on-call coverage obligations. We need phones that stay up regardless of what’s happening with our internet connection.”
For Indianapolis Healthcare: Phones That Stay Live During Indiana Weather
Indiana weather doesn’t ask permission. Tornado watches, ice storms, derecho events — and during all of them, the worst thing that can happen to a medical practice or a healthcare support business is phone failure. Our Hybrid system includes built-in 4G LTE cellular failover. The moment internet fails, calls route through cellular automatically — within seconds, without anyone on your team touching anything. Your 317 number stays live, the auto-attendant keeps answering, and patients reach a live person. When internet restores, the system switches back on its own.
