Your Phone System Shouldn't Be the Weakest Link
Aging on-premises PBX systems cost too much, can't support remote workers, and lack the features modern businesses need.
Legacy PBX Systems Are a Money Pit
Traditional on-premises phone systems require expensive hardware, dedicated phone lines, maintenance contracts, and specialized technicians for every configuration change. Adding a new extension costs time and money. Moving an employee to a different desk requires a service call. International calls generate surprise bills. Businesses across Raleigh, Durham, and the Triangle spend $40 to $80 per line per month on legacy phone systems — and still don't get voicemail-to-email, call recording, mobile integration, or auto attendant features without expensive add-ons. Cloud VoIP delivers all these features at 40-60% lower total cost, with zero hardware investment and unlimited scalability.
Remote Workers Can't Use Your Office Phones
The shift to hybrid and remote work exposed a critical limitation of traditional phone systems: they're tied to physical locations. Employees working from home, traveling, or visiting clients can't answer their office extension, transfer calls to colleagues, or access company phone features. They resort to using personal cell phones, creating a fragmented communication experience that looks unprofessional to clients and makes collaboration harder for teams. Companies in Chapel Hill, Cary, and throughout the Research Triangle that adopted cloud VoIP give every employee their business phone capabilities on any device, anywhere — desk phone, laptop, or smartphone.
Unsecured Voice Systems Create Compliance Risk
Healthcare organizations discussing PHI over unencrypted phone lines face HIPAA violations. Defense contractors conducting CUI-related conversations on non-compliant systems risk CMMC findings. Law firms using consumer-grade communication tools jeopardize attorney-client privilege. Voice communications are often the forgotten component of compliance programs. PTG's managed VoIP solutions include call encryption, secure SIP transport, compliance-ready call recording, and integration with your security infrastructure to ensure your voice communications meet the same standards as your data systems.
From Legacy PBX to Modern VoIP in Four Steps
PTG manages the entire transition to cloud VoIP — no disruption to your daily operations, no lost calls, no missed beats.
Phone System Assessment
We audit your current phone system, call volumes, feature usage, line counts, and integration requirements. We identify what's costing you money and what capabilities you're missing.
Solution Design
Based on your assessment, we design the optimal VoIP architecture: cloud PBX, SIP trunking, Teams integration, or hybrid approach. Auto attendants, call flows, and user configurations are planned in detail.
Deployment & Training
We provision your new system, configure every extension and feature, port your existing phone numbers, deploy desk phones or softphones, and train your team on the new capabilities.
Managed Operations
PTG monitors call quality, manages system updates, handles adds/moves/changes, and provides ongoing user support. Your phone system is managed with the same rigor as your IT infrastructure.
What makes PTG's VoIP different from buying a phone system from a telecom vendor is integration. Your phone system becomes part of your managed IT ecosystem — monitored by the same team, protected by the same security controls, and backed up alongside your data. When we deploy VoIP, we also evaluate your network to ensure it can handle voice traffic with appropriate QoS settings, VLAN segmentation, and bandwidth allocation. Our AI agent Penny can serve as your intelligent virtual receptionist, routing calls, taking messages, and ensuring every caller reaches the right person. Combined with our managed IT services, your communications infrastructure becomes another smoothly managed component of your business technology.
Enterprise Phone Features at Small Business Prices
Cloud PBX & Hosted VoIP
Enterprise-grade cloud PBX eliminates on-premises phone hardware entirely. All call routing, voicemail, auto attendant, call queue, and conference calling features run in the cloud with carrier-grade redundancy. Add or remove users instantly, configure call flows through a web portal, and scale from 5 to 5,000 extensions without hardware changes. Cloud PBX includes unlimited local and long-distance calling, eliminating per-minute charges that inflate legacy phone bills. PTG manages the entire platform so your team never touches phone system administration.
Microsoft Teams Voice Integration
Transform Microsoft Teams from a chat tool into your complete business phone system. PTG deploys Teams Direct Routing or Teams Phone with calling plans to give every Teams user a direct dial number, external calling capability, and full PBX features — directly inside the application they already use every day. Employees can make and receive business calls from the Teams desktop app, mobile app, or Teams-compatible desk phone. For Triangle-area businesses already invested in Microsoft 365, Teams voice integration eliminates the need for a separate phone system entirely.
SIP Trunking
Keep your existing on-premises PBX while cutting phone line costs by switching to SIP trunks over your internet connection. SIP trunking replaces expensive PRI lines and analog circuits with digital voice channels that cost a fraction of traditional service. PTG provisions, configures, and manages your SIP trunks with QoS optimization and failover to ensure call quality matches or exceeds what you had with legacy circuits. This is the ideal first step for businesses in Raleigh-Durham that want immediate cost savings before a full cloud migration.
Unified Communications
Voice, video, chat, presence, file sharing, and screen sharing in a single platform. Unified communications (UCaaS) eliminates the productivity loss of switching between separate applications for different communication modes. See who's available before calling. Escalate a chat to a video call with one click. Share your screen during a phone conversation. PTG deploys and manages UCaaS solutions that bring all your communication channels together, enabling faster collaboration for teams across office, remote, and hybrid work environments.
Call Analytics & Recording
Gain visibility into your communication patterns with detailed call analytics: call volumes, peak hours, average hold times, missed call rates, and per-user statistics. Compliance-ready call recording with secure storage satisfies HIPAA, financial services, and legal requirements for documented communications. Call recordings are encrypted, retained according to your compliance policy, and searchable for quality assurance and dispute resolution. Managers can monitor live calls for training purposes with whisper and barge capabilities.
Auto Attendant & Call Routing
Professional auto attendant greets every caller with customizable menus that route calls to the right department or person without a human receptionist. Time-based routing sends after-hours calls to voicemail or on-call staff. Ring groups distribute calls across teams. Call queues hold callers with estimated wait times and music. PTG's AI agent Penny adds intelligent call handling that goes beyond simple menu trees — understanding caller intent and routing accordingly for a professional experience that impresses every caller.

VoIP & Business Phone Questions Answered
What is VoIP and how does it work?
VoIP (Voice over Internet Protocol) transmits phone calls over your internet connection instead of traditional phone lines. Your voice is converted to digital data, transmitted across your network, and delivered to the recipient with the same clarity as a traditional call. Modern business VoIP includes all the features of a traditional PBX — extensions, voicemail, auto attendant, call transfer, conference calling — plus advanced capabilities like video conferencing, mobile apps, and Microsoft Teams integration.
How much does business VoIP cost in Raleigh-Durham?
Cloud VoIP typically costs $20 to $40 per user per month, compared to $40 to $80 per line for traditional phone service. Most PTG VoIP clients save 40-60% on their monthly phone costs while gaining features that would cost thousands extra on a legacy PBX. Every engagement starts with a free phone system assessment to identify your exact savings potential. Call 919-348-4912 for a custom quote.
Can I keep my existing phone numbers?
Yes. PTG ports your existing phone numbers to the new VoIP platform with zero downtime. Number porting typically takes 5 to 15 business days depending on your current carrier. During the porting process, your phones continue to work normally on the old system until the exact moment the numbers transfer to VoIP. We coordinate the cutover timing to ensure no calls are missed during the transition.
Will VoIP work with my internet connection?
Most modern business internet connections easily support VoIP. Each simultaneous call requires approximately 100 Kbps of bandwidth. PTG assesses your internet connection during the phone system assessment and configures Quality of Service (QoS) settings to prioritize voice traffic. If your current connection is insufficient, we'll recommend upgrades and leverage our master service agent partnerships to get the best internet pricing available.
Can VoIP integrate with Microsoft Teams?
Yes. PTG deploys Microsoft Teams Direct Routing and Teams Phone to turn Teams into a full business phone system. Every Teams user can make and receive external calls using their business number directly in the Teams app on their desktop, laptop, or smartphone. For businesses already using Microsoft 365, this eliminates the need for a separate phone system and gives employees one application for calls, chat, video, and collaboration.
Is VoIP reliable enough for business?
Enterprise cloud VoIP platforms deliver 99.99%+ uptime with carrier-grade redundancy. PTG's managed VoIP maintains 99%+ uptime across all client environments. Unlike on-premises PBX systems that have a single point of failure, cloud VoIP runs on geographically distributed infrastructure. If one data center experiences an issue, calls automatically route through another. For businesses that require maximum redundancy, we configure automatic failover to mobile phones during any connectivity interruption.
How long does it take to deploy VoIP?
PTG typically deploys business VoIP in one to two weeks from contract signing. This includes system configuration, phone provisioning, user setup, number porting initiation, and on-site installation and training. For organizations with complex call routing, multi-site deployments, or compliance requirements, the timeline may extend to three to four weeks. We can also run parallel systems during the transition if needed.
Do you provide VoIP desk phones or can we use existing phones?
Both. PTG offers high-quality VoIP desk phones from Yealink, Poly, and other enterprise manufacturers with buy or lease options. We also deploy softphone applications on computers and smartphones for employees who prefer software-based calling. In some cases, existing SIP-compatible phones can be reused. During the assessment, we recommend the hardware approach that best fits your team's work style and budget.
Is VoIP compliant with HIPAA and other regulations?
Yes, when properly configured. PTG deploys VoIP with encrypted SIP transport (TLS/SRTP), secure call recording with compliant storage and retention, access controls, and audit logging. We configure VoIP to meet HIPAA, CMMC, PCI DSS, and other regulatory requirements for voice communications. Healthcare practices and defense contractors in the Triangle trust PTG for phone systems that meet the same compliance standards as their data infrastructure.
Do you provide VoIP service on-site in the Triangle?
Yes. PTG is headquartered in Raleigh and provides on-site VoIP deployment, desk phone installation, training, and ongoing support throughout Raleigh, Durham, Chapel Hill, Research Triangle Park, Cary, and Apex. Our local engineers handle everything from initial network assessment to desk phone placement and user training. Remote management and monitoring are available 24/7 for all VoIP systems.
