Auto Dealer VoIP Phone System in Marietta, GA

Auto Dealer VoIP Phone System in Marietta, GA | COMNEXIA

Why Marietta Dealerships Are Replacing Legacy PBX with Hosted VoIP

Auto dealerships on Cobb Parkway and Barrett Parkway run on phone calls: sales desks negotiating trades, F&I offices walking buyers through contracts, and service advisors scheduling appointments. A legacy on-premise PBX that drops calls during peak hours or routes service calls to the wrong department costs real deals. COMNEXIA, headquartered in Roswell, GA and in business since 1991, deploys hosted VoIP and Microsoft Teams Phone systems built specifically for the operational and compliance demands of franchise and independent dealerships across Marietta and the broader metro Atlanta market.

The Compliance Problem Your Phone System Creates Under the FTC Safeguards Rule

The FTC Safeguards Rule (16 CFR Part 314) requires auto dealers to protect customer financial information, and your phone system is part of that obligation. Call recordings containing Social Security numbers discussed in F&I, voicemails left by customers referencing account details, and softphone traffic crossing your dealership network all constitute nonpublic personal information under the rule. COMNEXIA segments VoIP traffic into a dedicated voice VLAN, separate from the dealership management system (DMS) VLAN where CDK Global, Reynolds and Reynolds, or Dealertrack data lives. That network and DMZ segmentation is documented in writing and maps directly to the 16 CFR 314.4(e) requirement for access controls and 314.4(f) for monitoring covered information systems.

What COMNEXIA Actually Deploys for a Marietta Dealer

The specific components depend on your rooftop count and existing infrastructure, but a standard deployment for a Marietta single-point franchise dealer includes the following.

• Microsoft Teams Phone with SIP trunking: Direct Routing via a certified SBC (Session Border Controller) connects your existing PSTN numbers to Teams Phone, so sales and service desks work from the same platform as internal chat and video without buying a separate PBX appliance.
• Hosted PBX auto-attendant and call routing: Separate call trees for Sales, Service, Parts, and F&I, with after-hours routing to a mobile Teams client rather than a generic voicemail box. Missed sales calls are logged, not lost.
• E911 compliance per Georgia law: Each physical station and registered softphone location is assigned a dispatchable address in the 911 database. Multi-location dealers with a Marietta store and additional Atlanta-area rooftops get location-specific E911 records for each site, meeting Kari's Law and Ray Baum's Act federal requirements.
• QoS configuration on the LAN and WAN: Voice traffic is tagged DSCP EF (Expedited Forwarding, code 46) and queued ahead of general data traffic at every managed switch and router. Without this step, a large CDK Global DMS data pull or a simultaneous Windows Update can cause audible jitter on active calls.
• SD-WAN or redundant business internet: COMNEXIA provisions a secondary ISP circuit or SD-WAN policy that fails over VoIP traffic automatically if your primary connection drops. For a busy Marietta service lane, a 60-second outage during morning check-in is not acceptable.
• Secure CRM and DMS integration: Where your CRM or DMS supports it, inbound caller ID is matched against customer records in Dealertrack or Reynolds and Reynolds so the service advisor sees the customer name and RO history before answering. COMNEXIA tests and documents each integration point rather than assuming it works after deployment.

How the Deployment Process Works

COMNEXIA uses a documented onboarding checklist, not a verbal walkthrough. Before cutover, we audit your current phone bill for ported numbers, confirm number portability with the incumbent carrier, and set porting timelines in writing. Network readiness is validated against QoS requirements before a single handset is provisioned. Staff on the sales floor and service advisors get role-specific training on Teams Phone call handling, transfer, and voicemail-to-email, which is distinct from general Teams training and takes roughly 45 minutes per group. Post-deployment, your system is monitored via our RMM platform (NinjaOne) for SBC health, call quality metrics, and firmware on managed endpoints. Any issues generate a ticketed help-desk case, not an email chain.

Why a Security-First MSP Matters for Dealer VoIP

VoIP fraud, specifically toll fraud via unauthorized SIP registration, cost U.S. businesses hundreds of millions of dollars annually. COMNEXIA locks SIP trunks to authenticated IP ranges, disables international dialing by default unless a dealership has a documented business need, and reviews call detail records monthly as part of standard reporting. That monthly report also covers call volume by department, missed call rates by queue, and any firmware patches applied to SBC or endpoint hardware. It gives your dealer principal a clear picture of phone system health alongside the rest of your IT environment.
