Business Phone Systems
for JoCo’s Best Businesses
Johnson County is one of the wealthiest counties in the United States — and the businesses here set the professional standard for the entire KC metro. A 913 phone number that answers professionally, routes every call correctly, and stays up when internet has a bad day isn’t optional in this market. It’s the cost of doing business at this level.
AT&T Copper Retirement — Kansas: 24 Wire Centers, June 2026
AT&T grandfathered 24 Kansas wire centers on October 15, 2025 — including facilities serving the Overland Park and Johnson County corridor. No new copper orders or changes accepted. Full decommissioning begins June 2026 with 90 days notice. We migrate 913 businesses off copper and onto SIP trunks as part of every installation — your existing number ports cleanly, no interruption, usually done in a day.
Overland Park Businesses Set the Standard — Your Phone System Should Too
Johnson County residents and businesses have a running joke: the rest of Kansas thinks JoCo is arrogant, and JoCo doesn’t care. There’s something to it — Johnson County is home to some of the most successful businesses in the Kansas City metro, and the standard for professional presentation is genuinely higher here. Garmin’s U.S. headquarters is in Olathe, right next door. The T-Mobile presence from the legacy Sprint campus along College Boulevard is substantial. Black & Veatch operates here. Corporate Woods, Nall Hills, and the Leawood business corridors along 119th and State Line are home to hundreds of companies in the 10–100 employee range that are doing serious business and need phone systems that match.
And yes, Arrowhead is technically across the state line in Missouri, but every Chiefs fan in Johnson County knows that Patrick Mahomes and the Kingdom belong to all of us. The point is that JoCo businesses are plugged into both Kansas and Missouri — many have clients on both sides of the state line, and the 913 area code is as recognizable to a KC metro client as the 816.
The Overland Park phone system market has a notable concentration of Cisco Call Manager systems — driven by the Sprint/T-Mobile corporate culture that made Cisco the enterprise standard for a decade — alongside Avaya IP Office in professional services firms and NEC SL2100 in the SMB market along College Boulevard and Metcalf. All three platforms are end-of-life or effectively orphaned. We replace them all.
Your 913 Number — and Business Texting On It
We provision new Overland Park business numbers in the 913 area code, or port your existing 913 number at no service gap. We also text-enable your 913 business line — so when clients text your main number (which they’re absolutely doing already, to someone’s personal cell), those messages land in a shared desktop inbox your whole team can manage professionally. Outbound texts show your 913 number. No personal cells involved. For the professional services businesses of JoCo where client communication needs to be documented and professional, this matters.

⚠️ Legacy Systems We Replace in Johnson County
- Cisco CUCM (older versions) — Heavy penetration from Sprint/T-Mobile corporate culture. Versions 12.5 and earlier approaching end of manufacturer support.
- Avaya IP Office — Common in professional services, insurance, and healthcare-adjacent firms. Post-2023 bankruptcy, KS dealer options contracted.
- NEC SL2100 / SV9100 — Widespread in JoCo SMB market. Hardware sales ended Dec 2024.
- ShoreTel — Mitel acquired ShoreTel, then Mitel filed Chapter 11 in 2023. JoCo had meaningful ShoreTel deployments that are now effectively unsupported.
JoCo’s tech-forward business culture can create a false sense of security about legacy systems — “we’re a tech company, we’ll handle it” — until the moment they can’t, and a 30-person professional services firm is on a conference call with a client from Chicago when the main unit fails.
“We’re a 24-person healthcare consulting firm in Corporate Woods. We’re on a ShoreTel system that Mitel bought and then effectively abandoned when they went bankrupt. Our annual support contract just went from $3,100 to $7,900 because there are fewer vendors who’ll touch it. We’re paying almost $8,000 a year to maintain a system that’s on life support. That’s more than it would cost to replace it with something modern and actually supported.”
Integrations JoCo Businesses Expect
Phonewire’s system integrates with Salesforce, Microsoft 365, Zoho CRM, and other platforms common in Overland Park’s tech-forward business environment. When a call comes in, the caller’s CRM record surfaces on screen. When the call ends, the activity logs automatically. For a healthcare consulting firm, a financial services company, or any professional services business where every client interaction matters, this integration turns your phone system from a cost center into a revenue tool.
