Cloud VoIP and Hosted PBX for Cornelius Businesses
Most Cornelius businesses we talk to today are ready to leave on-site phone equipment behind for good. A hosted PBX system moves your phone system into the cloud instead of a box sitting in a closet, so there’s no aging hardware to maintain and no technician visit required every time you need a small change. Our hosted VoIP systems include:
- Auto attendant to greet and route callers automatically
- Voicemail-to-email, delivered straight to your inbox
- ConnectUC, our mobile and web softphone app, so your team can make and receive business calls from a smartphone, laptop, or web portal — no desk phone required
- Multi-location support, so offices across Cornelius, Charlotte, or anywhere else run on one unified system
- Desk phones from Yealink’s T4 and T5 series, for teams that want dedicated hardware alongside the softphone

How the Switch Works
Moving to a hosted phone system doesn’t mean tearing out your existing wiring or shutting your office down for a day. We build your new system in the cloud first — extensions, call routing, greetings, and all — while your current lines stay live. Once everything checks out, we schedule the number port from your existing carrier and cut over with minimal downtime, usually with only a few minutes of interruption, if any at all. Desk phones arrive pre-configured, so when they show up, your team plugs them in and they’re already registered to the right extension. Cornelius’s growth along the Lake Norman shoreline and the office and retail space near the I-77 exit 28 corridor keeps adding new tenants who need dependable multi-line phone service, and we size each system to the number of employees and call volume a location actually has, not a generic package.
Built for How Cornelius Does Business
Cornelius grew up around a cotton mill on the edge of what became Lake Norman, and downtown Cornelius along Catawba Avenue has since earned a reputation as the antique capital of North Carolina, packed with antique shops, boutiques, and small restaurants. Meanwhile the lakefront is lined with marinas, boat dealers, and seasonal service businesses, and the I-77 corridor brings in corporate offices, medical practices, and light-industrial tenants. Whatever your business is built around, your phone system should reflect it. Antique shops and boutique retailers downtown need a system a single employee can run from the sales floor without missing a call, while marina and boat service businesses along the lake see call volume swing heavily with the season and need something flexible enough to scale with them. Add the medical and dental offices, law practices, and corporate tenants filling out the rest of Cornelius, and we’ve installed and supported phone systems across nearly every kind of business the town has.
Structured Cabling and On-Site Support
Building out a new office or storefront in Cornelius? We handle structured cabling for phone and data lines alongside your phone system installation, so the wiring is in place before you move a single desk in. And because we’re a local Charlotte-area company, on-site support and repairs for existing systems are never far away. 
Still Running an On-Premise System?
Not every Cornelius business is ready to move to the cloud, and that’s fine. We still install, support, and repair on-premise phone systems, including systems from major manufacturers. If you have a system that’s working but needs an upgrade, a technician to relocate it, or occasional repairs, we can help without pushing you into a full replacement before you’re ready.
Why Cornelius Businesses Choose DS1
We’ve been serving the greater Charlotte region for over thirty years, and Cornelius and the rest of the Lake Norman towns are part of our core service territory, not an afterthought. Support calls go to a local technician who knows the system, not an overseas call center. Changes to your system, big or small, are included at no extra charge.

FAQ
Do you support businesses in Cornelius, or just Charlotte?
Cornelius and the rest of the Lake Norman towns are part of our core service territory. We’ve installed and supported phone systems for businesses throughout the region for years, alongside our Charlotte-area work.
Is hosted PBX better than an on-premise system?
For most small and mid-sized businesses, yes. Hosted PBX eliminates the upfront hardware cost, reduces maintenance calls, and makes it easy to add users or locations without rewiring anything. If you have a specific reason to keep an on-premise system, we can talk through that too — give us a call.
Can I keep my current phone number if I switch?
In almost every case, yes. We handle the number transfer as part of the setup process.
What happens if the internet goes down?
Our hosted systems include call forwarding to a mobile phone as a backup, so you won’t miss important calls during an outage.
Do you work with businesses that have multiple locations?
Yes. We regularly set up multi-location businesses, including companies with offices in both Cornelius and the Charlotte area, on a single unified phone system so employees can dial each other by extension.
What if I’m not ready to give up my current phone system yet?
That’s fine. We still support and repair on-premise systems for Cornelius businesses. Call us and we’ll talk through your options honestly, including whether staying put makes more sense for now.
What does it cost to switch to a hosted phone system?
Cost depends on how many users and phones you need, and whether you want physical desk phones or plan to use the ConnectUC app instead. Call us for a free quote based on your actual office setup rather than a generic per-seat estimate.
Do you install phone systems for new construction or office buildouts?
Yes. If you’re building out a new office or moving into an existing space in Cornelius, we can plan the phone system and structured cabling together so the wiring is in place before drywall goes up.
Do you support legacy phone systems too?
Yes. We service a range of legacy business phone systems in addition to hosted VoIP, so if you’re not ready to switch or just need a repair, we can help.
How do I get started?
Call 704-729-7210 for a free consultation. We’ll ask a few questions about how your business operates, do a quick site survey if needed, and recommend a system that fits.
Do you install phone systems for medical or professional offices?
Yes. We work with a range of Cornelius medical, dental, and professional offices, where reliable call routing and HIPAA-conscious voicemail handling matter. We can also integrate features like call queuing for busy front desks.
