Modern Business Phone Systems That Save You Money
Old phone systems are expensive and hard to change. VoIP (Voice over Internet Protocol) runs your calls over the internet connection you already have, so you get big-company phone features for a lot less. Most businesses see a smaller monthly phone bill after switching.
NGT Technology is a multi-vendor VoIP provider experienced with 3CX, serving businesses across Lawrenceville and metro Atlanta. 3CX, RingCentral, Microsoft Teams Phone or something else, we'll recommend what fits your business.

Solutions
Common Phone System Problems We Solve
💸
Expensive Traditional Phone Bills
No more per-minute charges. VoIP over the internet you already have usually means a smaller monthly phone bill.
📉
Dropped Calls & Poor Call Quality
We set up QoS, a dedicated voice VLAN and bandwidth controls so your calls get priority on the network and sound clear.
🏠
No Remote Work Capability
Mobile apps and softphones let your team use the full phone system from their own phone or laptop, wherever they are.
📈
Outgrowing Current System
VoIP grows with you. Add extensions, locations and users in minutes without new hardware or wiring.
📊
Lack of Call Analytics & Reporting
Live dashboards, call records and reports show you who's calling, when, and how long they wait.
🏢
Multiple Locations Need Unified Comms
One system across every office: dial any extension, manage it all in one place and transfer calls between locations with a click.
Why Choose Us
Installed By a Local Team, Not a Faceless Reseller
Martin Gonzalez founded NGT Technology in Lawrenceville in 2019 and personally scopes every VoIP cutover we take on. He's experienced with 3CX and has installed phone systems for dental practices, law firms, insurance agencies, and multi-location small businesses across Gwinnett County and metro Atlanta.
Multi-Vendor Expertise
3CX is our preferred platform, but we deploy and manage RingCentral, Microsoft Teams Phone, and other leading providers too. We recommend the platform that fits your business, not the one with the highest reseller margin.
Hands-On Installation From Our Local Team
Equipment selection, on-site network setup, extension programming, parallel testing next to your old system, go-live and hands-on training for your team. Most installs are done on-site by us, not handed off to an offshore call queue.
Ongoing Management With a Real Response Time
Every VoIP support ticket gets a same-day response during business hours, and we aim to call back on most within 30 minutes. We handle firmware updates, security patches, user changes and integration problems through our help desk, often as part of a bigger managed IT services plan.
What Actually Matters
The Three Features Most Businesses Actually Use Daily
The full feature list above is long. In real life, almost every business we set up on 3CX or Teams Phone leans on the same three features more than anything else. Get these right and you'll get most of the value.
📲
1. Mobile Softphone Apps
Your office phone, on your cell. Make and take business calls from anywhere using your office number, without giving out your personal number. It's the feature people thank us for most after the switch.
🎯
2. Call Queues & Ring Groups
Inbound calls roll through your team in a controlled order instead of ringing every desk at once. Great for front desks, insurance agencies, dental offices, and any team handling steady call volume.
🔌
3. CRM Integration
3CX and RingCentral both pop up the matching CRM record when a known number calls: Salesforce, HubSpot, Zoho or industry tools. Your team knows who's calling before they say hello.
Investment
What a VoIP System Typically Costs
VoIP pricing has two sides: a one-time installation cost and a monthly per-user cost. The ranges below reflect what most Gwinnett County small businesses pay us for a 10-30 extension deployment. Hardware (desk phones, headsets) is separate and depends on the brand you choose.
| Cost Component | What It Covers | Typical Range |
|---|---|---|
| Installation (one-time) | Network assessment, system provisioning, extension programming, parallel test, on-site cutover, and team training | ~$300 - $800 |
| Monthly Per User | 3CX or platform license, SIP trunking, mobile + desktop softphones, voicemail-to-email, call recording | ~$20 - $35 / user / month |
| Ongoing Support | Firmware updates, user changes, integration troubleshooting via help desk (often bundled with managed IT) | Bundled or scoped |
| Network Upgrades (if needed) | QoS settings, voice VLAN and a backup internet line for failover, handled by our network services team | Scoped per site |
Many businesses earn back the installation cost within a few months from phone-bill savings. Free discovery call available, and we'll run the numbers against your current carrier.
Common Questions
Frequently Asked Questions About VoIP
VoIP (Voice over Internet Protocol) turns your voice into data and sends it over the internet, so you can make calls from a desk phone, a computer or a phone app. It replaces old copper phone lines with the internet connection you already have, which usually costs less and gives you more features.
Most businesses pay less each month after switching. How much depends on your current provider, how many lines you have and your long-distance volume. Book a free discovery call and we'll compare it against your current bill.
Each simultaneous call uses approximately 100 Kbps. Basic business internet typically handles 10-20 concurrent calls with ease. Our network services team runs a full assessment of speed, latency, jitter, and packet loss before installation, and configures QoS and a dedicated voice VLAN where needed for clean call quality.
Yes. Moving your numbers over (porting) is standard and usually takes 7 to 14 business days. We set up temporary forwarding during the switch so calls keep coming in, and your customers won't notice a thing.
For a typical small business (10-30 extensions), we plan 2-4 weeks end-to-end. Week 1 is the network assessment and equipment ordering. Week 2 is provisioning, extension programming, and parallel testing alongside your existing system. Week 3 is the go-live cutover and on-site training. Number porting can run in parallel but is gated by your existing carrier and usually adds another 7-14 days.
We build failover into every deployment. Inbound calls automatically reroute to mobile softphones, a backup mobile number, or an answering service when the primary internet goes down. For businesses that depend on phones (insurance agencies, medical practices, law firms), we also recommend a secondary internet circuit on a different carrier so VoIP keeps running through outages of the primary connection.
