Your phone system should work as hard as you do


Traditional phone systems are expensive to maintain, rigid to modify, and increasingly difficult to support as hardware ages. They don't integrate with the way your team actually works — remote, hybrid, or across multiple locations. NOC Voice is built for how St. Louis businesses operate today. Your team can take calls on a desk phone, a laptop, or a mobile app — from the office or from home — without the caller knowing the difference. Changes to your phone system take minutes, not service calls. And because it's hosted in the cloud, there's no hardware to fail and no closet full of equipment to maintain.

What's included with NOC Voice

Crystal-clear voice & video calling


Stable, HD voice quality over your business internet connection. Video conferencing is built in for internal meetings and client calls.

Business SMS texting


Send and receive text messages from your business phone number. Keep client communications professional and documented, even when your team is on the go

Advanced call routing & auto-attendant


Build the call flow your business needs — custom greetings, department routing, after-hours handling, and voicemail-to-email — without a phone technician. Changes are made through a web portal in minutes.

Mobile & desktop apps


Your team's business phone follows them wherever they work. The NOC Voice mobile app turns any smartphone into a full-featured business phone — same number, same features, fully integrated with the office system.

Local support — managed by NOC Technology


Unlike national VoIP providers who hand you off to an overseas call center, NOC Voice is managed by the same St. Louis area team that handles your IT. If something isn't working, you call us — and we fix it.

Cost with VoIP providers like RingCentral adds up fast.



Ours stays simple. We're not trying to upsell you into a system you won't use and don't need.

When you choose NOC VoIP, you're choosing:

  • Infrastructure alignment — your phones live in the same AWS account as your backups and disaster recovery
  • One support number — instead of explaining your network to a VoIP vendor and your infrastructure to us, you just talk to us
  • Pricing that makes sense — $22.50/mo for softphone, $30/mo for hardphone + lines. Not $50+ per user for enterprise features you don't need
  • 3CX reliability — battle-tested, carrier-grade, built for businesses like yours

  • Remote and hybrid work support — staff can work from anywhere without call forwarding workarounds

Frequently Asked Questions

What is VoIP and how does it work for businesses? +
VoIP (Voice over Internet Protocol) is a phone technology that transmits voice calls over an internet connection instead of traditional copper phone lines. For businesses, VoIP delivers all the features of a traditional phone system — plus advanced capabilities like mobile apps, video calling, and business SMS — at a lower cost and with greater flexibility than legacy PBX systems. NOC Voice is NOC Technology's managed VoIP service for St. Louis businesses.
Can we keep our existing business phone numbers when switching to VoIP? +
Yes. NOC Technology manages number porting for all NOC Voice clients. Your existing business phone numbers transfer to the new system — your clients and partners call the same numbers they always have, with no interruption in service during the transition.
Is VoIP reliable enough for business use? +
Yes, when deployed on a properly configured business internet connection. NOC Technology assesses your internet infrastructure before deployment to ensure sufficient bandwidth and Quality of Service (QoS) settings for crystal-clear calls. NOC Voice operates on enterprise-grade cloud infrastructure with high availability and automatic failover, so your phones stay up even if one data center has an issue.
How much does a business VoIP phone system cost in St. Louis? +
NOC Voice is priced per user per month and includes all features — no tiered plans with key features locked behind a higher tier. Most St. Louis businesses find VoIP costs 30–50% less than their legacy phone system when factoring in hardware maintenance, long-distance charges, and per-feature fees.
