Business Phone Systems in Austin — Installed On-Site, Supported by Someone Who Actually Answers.
Cloud, hybrid, and on-premise phone systems for Austin-area businesses. We provision 512 and 737 numbers, port every extension you already have, and turn on business texting the day we cut over. Zero downtime. Predictable pricing. A technician in your building — not a chatbot in another country.
The “we grew three times and our phones didn’t” problem.
A SaaS company in the Domain started with 8 people and a cheap hosted plan three years ago. They’re 45 now, split between the Domain, a satellite in South Austin, and half the team remote across Round Rock, Cedar Park, and Pflugerville. Their phone system is still the same consumer-grade platform — no call recording, no real call queues, no way to spin up a proper support line. The CFO keeps asking why nobody answers the main number.
That’s the Austin call we get most often. We replace the half-baked platform with a real business phone system that scales, port every 512 and 737 number, and give the team a single unified experience across three offices and a couch in Cedar Park. Same-day cutover. Zero downtime.
Still running something nobody makes parts for?
If your Austin 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 Austin businesses.
Tech Startups & SaaS
Growth-stage companies around the Domain, East Austin, and South Congress need phone systems that scale with hiring sprints. We deploy unified communications, call queues for support and sales, CRM integration with HubSpot and Salesforce, and remote-work setups that match hybrid schedules.
Healthcare & Medical Practices
Independent practices across Westlake, North Austin, and the Seton medical corridor. HIPAA-aware systems with secure voicemail-to-email, encrypted call recording, after-hours on-call routing, and EHR integration.
Legal, Accounting & Professional Services
Law firms, CPAs, and consultants from Downtown to Westlake to Round Rock. Call recording for compliance, mobile apps for attorneys, and business texting from the firm’s main number — so client communication stays with the firm, not in someone’s personal text messages.
Construction, HVAC & Trades
Austin’s growth means trades are flat-out busy. We deploy ring groups, cell-phone-as-extension setups, and SMS-to-tech workflows so HVAC, plumbing, electrical, and construction dispatchers can route service calls without missing a beat.
Cellular failover for grid events and outages.
ERCOT drama. Severe storms rolling out of the Hill Country. Fiber cuts from construction on MoPac. When the internet or power drops, cloud phones drop with it — unless you have cellular failover. We build it into every Austin deployment. When the primary circuit fails, the system cuts over to 4G/5G automatically. Your 512 or 737 number keeps ringing. Your team keeps answering. You find out from a monitoring alert, not a customer.
Business texting from your main 512 or 737 number.
Your customers already text. Your main number should too. We enable compliant business SMS from the same line customers already call. Confirm appointments, send quotes, follow up after a demo. Every conversation is visible to your whole team and stays with the business when an employee moves on.
