We Install Business Phone Systems
Anywhere in the United States
From a single-office law firm in St. Louis to a 40-location healthcare network turning up on the same day from Seattle to Miami — Phonewire coordinates nationwide business phone system installations with the same care and accountability you’d expect from the person who’s been your local phone guy for 25 years. Because that’s exactly what we are. We just also happen to do it coast to coast.
AT&T and Lumen Copper Retirement — Every U.S. Market Is Affected
AT&T has grandfathered over 900 wire centers nationwide as of October 15, 2025 — including 271 in Texas, 123 in Illinois, 111 in Ohio, 105 in Michigan, and dozens more in every major business market. Lumen (CenturyLink) is retiring copper infrastructure in its territories — Iowa, Minnesota, Nebraska, Colorado, and others — through 2029. If your business has copper POTS lines anywhere in the country, the forced migration to SIP trunking is coming. Phonewire handles POTS-to-SIP migration nationwide as a standalone service or as part of a full system installation, with number porting coordinated in the background and no interruption to your existing service.
Small Business Feel. Nationwide Installation Reach.
Here’s the honest version of what Phonewire is: we’re a company that’s been installing business phone systems since 1998, built on the idea that businesses deserve real support from real people who know their name and their configuration — not a ticket queue and an offshore Level 1 agent reading from a script. That’s who we are at our core, and it’s why our customers stay with us.
We’re also a company that can coordinate a simultaneous same-day installation across 12 states. We can turn up 40 locations in a single business day with installation teams on the ground in Seattle, Phoenix, Charlotte, and Boston all cutting over at the same pre-agreed time. We can manage the project scope, coordinate the on-site work, handle number porting across multiple carriers, and be the single point of contact for a multi-location business that needs one vendor managing the whole thing — not a patchwork of regional installers each doing their own version of the project.
This isn’t a contradiction. Knowing your customers by name and being able to deploy nationally are not mutually exclusive. We built the relationships and the coordination infrastructure to do both, and we do it for businesses ranging from a single-location medical practice in Lexington to enterprise multi-site deployments across every time zone.
Multi-Location & Multi-State Installations — Coordinated by One Team
Retail chains, healthcare networks, financial services firms, law firms with satellite offices, logistics operations with facilities in multiple regions — if you have more than one location and you’ve been putting off your phone system upgrade because “coordinating multiple vendors sounds like a nightmare,” this is what we built for. One project manager. One quote. One cutover timeline. All locations go live on schedule.
The Multi-Location Installation Process
Single Quote, All Locations
We scope every site, review existing infrastructure, and produce one consolidated quote covering hardware, installation labor, SIP trunking, and number porting for every location.
Number Porting Coordination
We manage porting with every carrier involved — AT&T, Lumen, Comcast, Spectrum, Windstream, whatever’s at each site — with all ports timed to complete before cutover day.
Installation Teams On-Site
Our installation teams are on-site at every location on cutover day — whether that’s 2 locations or 40. Every technician is briefed on the project scope before arrival.
Synchronized Cutover
We coordinate a synchronized cutover window — all locations go live together at a pre-agreed time. Your team wakes up that morning with the same phone system in every office.
📊 U.S. Copper Retirement by Region — What We’re Seeing in the Market
AT&T Copper Wire Centers Retiring — Top States
Sources: FCC filings, AT&T state grandfathering notices, Oct 2025. Lumen (CenturyLink) territory not included.
Legacy Systems Phonewire Replaces Nationwide
Based on Phonewire’s installed-base migration experience. Avaya’s two Chapter 11 filings and NEC’s Dec 2024 hardware exit drove the replacement wave.
Migration Urgency — Average Days of Notice Before Copper Goes Dark
90 days sounds like a lot of time. It isn’t. Businesses waiting for the notice before planning have routinely discovered the installation window is already booked.
Phonewire System Options — Relative Monthly Cost Per User
Hybrid hardware: $3,499 + $699/yr (≤20 users). Optional cellular failover, all handsets, installation, and U.S. support — no per-user monthly fees.
Wherever Your Business Is, We Install There
We’ve installed in 50-story office towers in Manhattan, in oil and gas field offices in Midland, Texas, in veterinary practices on horse farms in the Kentucky Bluegrass, in Boeing supplier facilities outside Seattle, in casino resort properties in Las Vegas, in biotech startups in the Research Triangle Park, in defense contractor offices in San Diego, and in cattle ranching operations in eastern Colorado where broadband sometimes means a Starlink dish and cellular failover isn’t optional — it’s the point. We don’t have a preferred region. We install everywhere.
West Coast & Pacific Northwest
Seattle’s aerospace and tech ecosystem. Portland’s manufacturing and healthcare market. The Bay Area’s complex telecom infrastructure and its love of cloud systems that somehow still need a competent human being to configure them. Los Angeles entertainment, healthcare, and the logistics operations running the Port of LA. We install in all of it. California’s AT&T wire center retirement count is one of the highest in the nation — if your West Coast office is on copper, that conversation needs to happen.
Northeast & Mid-Atlantic
New York City’s density means our installation teams navigate elevators, freight restrictions, building management permissions, and telecom closets shared between 40 tenants. Boston’s healthcare and biotech ecosystem — the Longwood Medical Area, the Route 128 tech corridor — has specific Cisco and Avaya system concentrations we handle routinely. Philadelphia, Baltimore, Washington DC — the federal contractor market in the DC metro is one of the most active we see anywhere in the country.
Southwest & Mountain West
Phoenix’s massive healthcare and financial services growth. Tucson’s defense and aerospace sector around Davis-Monthan AFB. Albuquerque’s Sandia National Laboratories and the professional services ecosystem around it. Las Vegas hospitality — when a Strip property needs a front desk and PMS integration, we handle it. Salt Lake City’s tech sector. Scottsdale’s corporate headquarters corridor. The Southwest is one of our most active growth markets.
Southeast & Gulf Coast
Atlanta’s enormous corporate headquarters concentration — Delta, Coca-Cola, Home Depot, UPS, and the professional services ecosystem around them. Charlotte’s banking sector. Raleigh-Durham’s Research Triangle healthcare and biotech market. Jacksonville and Tampa’s growing professional services economies. The Gulf Coast energy, maritime, and logistics operations from New Orleans to Pensacola. Miami’s international business community — where a phone system needs to handle calls from São Paulo as routinely as from Fort Lauderdale.
“We have 14 offices across 9 states. We’ve been on different phone systems in different locations — some cloud, some legacy hardware, three different carriers for SIP trunking. Every location has a different support contact. When something breaks in our Phoenix office, nobody knows who to call. We’ve been quoted between $180,000 and $340,000 by national integrators to standardize everything. We needed someone who could scope this project, manage it, and give us one number to call when anything in any office needs attention. That’s who Phonewire turned out to be.”
Cellular Failover — Deployed at Every Location, Simultaneously
Our Hybrid system’s 4G LTE cellular failover option protects every office against internet outages — automatically, within seconds, with no action required from staff. For multi-location businesses, this means every office in the network has the same failover protection on the same day. The call center in Tempe stays up when the ISP has a bad morning. The field office in Baton Rouge stays reachable during hurricane season. The branch in Minneapolis stays live through a January polar vortex. One feature, deployed everywhere, managed from one platform.
Business Texting — On Every Office’s Local Number
We text-enable every business number in your deployment — your 206 in Seattle, your 212 in New York, your 404 in Atlanta, your 213 in Los Angeles — so every office has a two-way text channel on its local number, with all messages routing to a shared team inbox. For multi-location businesses where clients interact with local offices, maintaining a local number identity while enabling modern text communication is the right balance. We provision this at every location as part of the installation. Business texting details →
