Services
Granite Telecommunications Solutions
POTS replacement, broadband, SD-WAN, UCaaS, IoT, and managed mobility — consolidated across 100+ carriers onto a single Granite account.
POTS Replacement — Analog Line Elimination
Granite's POTS replacement solution eliminates legacy analog phone lines before the FCC deadline drives carrier price increases or discontinuation. Cellular-based (4G LTE / 5G) or broadband replacements for fax machines, elevator phones, fire alarm panels, door access systems, and security systems. FCC-compliant, certifiable for NFPA 72, ASME A17.1B, and UL 864 applications. Granite manages the migration project across all locations and all legacy carriers — including audit, device inventory, and line-by-line conversion at scale.
Business Internet — Broadband & Dedicated Fiber
Broadband and dedicated fiber internet across AT&T, Verizon, Lumen, Comcast, Cox, Spectrum, and 100+ regional carriers — quoted, ordered, and managed through a single Granite account. Granite handles provisioning, billing consolidation, and first-line support across all carrier circuits. For multi-location enterprises managing dozens or hundreds of internet circuits from multiple carriers, Granite provides a single point of accountability rather than maintaining direct relationships with each individual carrier.
SD-WAN — Managed Software-Defined WAN
Managed SD-WAN layered on top of Granite's aggregated carrier network — delivering application-aware routing, automatic failover, centralized policy management, and cloud optimization across all enterprise locations. Granite's SD-WAN is carrier-agnostic by design, meaning it works over whichever combination of underlying circuits each location requires. Single-pane-of-glass management through GraniteView portal. Appropriate for enterprises with 50+ locations that need consistent WAN policy enforcement without managing separate SD-WAN overlays and underlying carrier relationships.
UCaaS — Hosted VoIP & Cloud PBX
Cloud-hosted unified communications replacing legacy PBX hardware at enterprise locations — delivered on Granite's carrier-grade network with guaranteed call quality SLAs. Includes auto-attendants, call queues, hunt groups, conferencing, voicemail-to-email, and Microsoft Teams integration. Granite UCaaS is purpose-built for the multi-location enterprise use case where 50 to 500+ sites need consistent phone service with centralized administration and a single monthly invoice rather than site-by-site deployments.
IoT & Connected Device Management
Cellular IoT connectivity and managed device services for enterprise networks — covering digital signage, environmental monitoring, building access, POS backup, and connected device management at scale. Granite aggregates IoT SIM connectivity across AT&T, Verizon, and T-Mobile with unified billing and a single management portal (GraniteView). Enterprises with large-scale IoT deployments across hundreds of retail, hospitality, or healthcare locations benefit from Granite's ability to provision and manage IoT devices under the same account structure as their voice and data services.
Managed Mobility — MDM & Wireless Expense
Managed mobility services for enterprise wireless fleets — mobile device management (MDM), wireless expense management, plan optimization, and carrier billing consolidation across AT&T, Verizon, and T-Mobile. Granite audits existing wireless spend, identifies unused lines and over-provisioned plans, and consolidates all wireless billing into the existing Granite invoice. Wireless expense management is particularly valuable for enterprises with 500+ mobile devices where carrier billing complexity creates significant administrative burden and cost leakage.
Network Security — DDoS, Firewall & Monitoring
Network security services delivered through Granite's managed infrastructure — DDoS mitigation, managed firewall, and 24/7 network monitoring. Security is applied at the network layer rather than requiring additional on-premises appliances at each location. For multi-location enterprises with budget and headcount constraints, Granite's network-layer security approach provides baseline protection without the operational complexity of managing per-site security equipment.
Industries
Built for Multi-Location Enterprises
Retail & Restaurant Chains
America's largest retail chains rely on Granite for POTS replacement, internet, SD-WAN, and IoT across hundreds to thousands of locations. Granite's consolidation model eliminates the operational overhead of managing separate carrier relationships for each location — replacing it with a single vendor, single bill, and dedicated account team.
Healthcare Systems
Healthcare networks use Granite for multi-site telecom consolidation, POTS replacement for life-safety systems (fire alarm, elevator, nurse call), dedicated internet for clinical locations, and managed voice for clinic phone systems — with HIPAA-compliant infrastructure and single-vendor accountability.
Financial Services & Government
Banks, credit unions, insurance companies, and government agencies use Granite for consolidated telecom management — PCI-DSS compliant connectivity, redundant circuits for mission-critical locations, and government-grade security for regulated environments. Granite holds GSA Schedule 70 contracts for government procurement.
Why Granite Telecommunications
Key Strengths
Granite's core value proposition is consolidating telecom spend across AT&T, Verizon, Lumen, Comcast, and 100+ other carriers onto a single Granite invoice. Enterprises managing 50–5,000 locations eliminate the administrative burden of managing direct relationships with multiple carriers, and gain a single point of contact for support, billing disputes, and escalations. Each location uses the best-fit carrier for that address while the enterprise manages a single vendor relationship.
Granite's POTS replacement program is specifically designed for enterprises with hundreds to thousands of legacy analog lines — elevator phones, fax machines, fire alarm panels, and access control systems that cannot simply be shut off. Granite audits the full analog line inventory, identifies replacement technology for each application, manages the migration timeline, and handles carrier disconnects — delivering a fully managed transition rather than a DIY replacement project.
GraniteView is Granite's enterprise portal providing centralized visibility across all services, all carriers, and all locations under the Granite account. Inventory management, ticket tracking, billing detail, circuit performance, and order status are accessible through one platform. For IT teams managing large multi-site telecom environments, GraniteView replaces the need to manage separate portals and billing systems for each carrier relationship.
Founded in 2002 and privately held, Granite has grown into the largest private telecom reseller in the US by focusing exclusively on the multi-location enterprise segment. Long-term relationships with major retail, healthcare, and financial services companies are maintained through dedicated enterprise account teams and a support model that scales with enterprise complexity. Granite processes over $1.5 billion in annual telecom spend on behalf of its clients.
