Can I keep my 256 number when switching to VoIP?

Yes. Phonewire ports your 256 Huntsville number from AT&T, WOW, or any carrier in 5-10 business days. Your number stays active the entire time.

Do you serve defense contractors and tech companies on the Arsenal?

Absolutely. We understand the communication needs of Redstone Arsenal contractors, MSFC-adjacent businesses, and the growing Cummings Research Park tech corridor. Secure, reliable phone systems are what we deliver.

How reliable is VoIP for Huntsville businesses?

More reliable than WOW or AT&T Alabama copper. When a summer storm knocks out service on the north side or Research Park, our cellular failover routes calls within 15 seconds. No waiting days for repairs.

Heads up, Huntsville business owners: AT&T is actively retiring copper across Alabama. The FCC cleared the path in 2022 and AT&T filed to discontinue legacy TDM services in 60 U.S. markets. If your office still runs a PRI, T1, or analog POTS lines, that infrastructure is on borrowed time. We move Huntsville businesses to SIP, cloud, or hybrid systems before the carrier sets the deadline for you.

The “we won a contract and doubled headcount in six months” problem.

An engineering contractor in Cummings Research Park lands a new Redstone contract and goes from 18 people to 40 in six months. The phone system they bought in 2016 can’t handle it. Call queues don’t work right. Remote staff — the ones working from home in Madison and Owens Cross Roads — are using personal cells. There’s no good way to record calls for contract documentation. And their current vendor is a one-person shop that’s underwater.

That’s the Huntsville call we get. We replace the aging system with something that scales, port every 256 and 938 number, set up proper call recording and mobile apps, and stand up a real support relationship. Same-day cutover. Zero downtime. The engineers can focus on the contract, not the phones.

Still running a system the manufacturer walked away from?

If your Huntsville 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 2009.

Built for Huntsville businesses.

Professional Services & Legal

Law firms, CPAs, and consulting firms supporting the contractor economy. Call recording for compliance, mobile apps for attorneys, and business texting from the firm’s main number — essential for professional, auditable client communication.

Cellular failover for severe weather.

North Alabama thunderstorms and tornado outbreaks that take down power and poles. Ice storms in January. Fiber cuts from construction. When the internet drops, cloud phones drop with it — unless you have cellular failover. We build it into every Huntsville deployment. When the primary circuit fails, the system cuts over to 4G/5G automatically. Your 256 or 938 number keeps ringing. Your team keeps answering. You find out from a monitoring alert, not a customer.

Business texting from your main 256 or 938 number.

Your customers, clients, and subcontractors already text. Your main number should too. We enable compliant business SMS from the same line clients already call. Confirm meetings, send quotes, coordinate project updates. Every conversation is visible to your whole team and stays with the business when an employee moves on.
