Voice over IP (VoIP) Services

Modern Voice Solutions for Modern Business

Simplify Voice. Upgrade from Legacy.

Traditional phone systems are outdated, expensive to maintain, and incompatible with today’s hybrid work demands. Copper POTS lines are being phased out by many carriers—leaving businesses with unreliable service and rising costs.

NCG helps businesses move to cloud-based voice systems that are flexible, scalable, and cost-efficient. We support VoIP migrations through trusted providers like RingCentral and AT&T Office@Hand, helping you transition from legacy setups with minimal disruption.

Whether you're consolidating voice infrastructure or setting up service across new locations, we guide you from selection through deployment—with long-term support included.

VoIP – FAQs

What VoIP and cloud phone systems does NCG provide?
NCG deploys and manages RingCentral and Office@Hand cloud phone systems for multi-site businesses. Our solutions include business VoIP service, unified communications (UCaaS), auto-attendant setup, call routing across locations, number porting, Microsoft Teams integration, and ongoing system support, replacing legacy PBX hardware with flexible cloud telephony.
Why use NCG to implement VoIP instead of buying directly from RingCentral?
NCG eliminates implementation risk through expert project management, network readiness assessment, and multi-location coordination. You get the same RingCentral or Office@Hand pricing but with pre-deployment bandwidth analysis, custom call routing design, seamless number porting, and post-launch optimization. We're compensated by the platform provider, so you receive white-glove implementation at no additional cost.
Can NCG help replace our old PBX phone system with cloud VoIP?
Yes. PBX-to-VoIP migration is our specialty. We assess your current system (Avaya, Cisco, NEC, Mitel, etc.), design a cloud phone replacement strategy, coordinate number porting from existing carriers, configure call flows and auto-attendants, and manage cutover to minimize disruption. Most clients eliminate $2,000-10,000+ in annual PBX maintenance costs while gaining mobility and disaster recovery capabilities.
What's the VoIP implementation process?
1. Assessment: Audit current phone system, call patterns, network capacity, and user needs
2. Design: Configure call routing, auto-attendants, user permissions, and integrations
3. Deploy: Coordinate number porting, provision devices, and conduct user training
4. Support: Manage go-live, troubleshoot issues, optimize call quality
Does NCG integrate VoIP with Microsoft Teams?
Yes. Both RingCentral and Office@Hand integrate with Microsoft Teams for unified communications. We configure the integration so users can make/receive business calls directly within Teams while maintaining centralized call management, reporting, and compliance features through your VoIP platform.
How does NCG ensure call quality and network readiness for VoIP?
We perform pre-deployment network assessments, including bandwidth analysis, QoS configuration recommendations, and internet circuit evaluation. For multi-site deployments, we coordinate with your internet provider (or source additional bandwidth) to ensure sufficient capacity. Post-launch, we monitor call quality metrics and resolve carrier or configuration issues affecting voice performance.
Can NCG support multi-location call routing and centralized management?
Yes. We specialize in VoIP for multi-site businesses: retail chains, healthcare systems, auto dealerships, hospitality groups, and franchises. NCG configures location-specific phone numbers, centralized auto-attendants, inter-office dialing, and unified call reporting across all sites while maintaining local number presence in each market.
Does NCG support call recording and compliance requirements?
RingCentral and Office@Hand include call recording capabilities for quality assurance and compliance. For regulated industries (financial services requiring FINRA compliance, healthcare with HIPAA considerations, call centers with PCI-DSS requirements), we configure appropriate recording policies, storage retention, and user consent workflows to meet regulatory obligations.
What happens to our existing phone numbers when switching to VoIP?
NCG manages the entire number porting process, submitting LOAs (Letter of Authorization) to current carriers, coordinating port dates, testing number functionality pre-cutover, and ensuring zero downtime during the transition. We handle single-location or multi-site porting projects, including toll-free numbers and DID blocks.
What types of businesses benefit most from NCG's VoIP solutions?
Organizations replacing aging PBX systems, multi-location businesses needing centralized call management, remote/hybrid teams requiring mobile calling capabilities, call centers requiring advanced routing and recording, and companies seeking disaster recovery for business telephony. Clients with 10+ users across multiple sites gain the most value from our implementation expertise and ongoing management.
