The Middleware Layer Between Carrier Networks and Enterprise Platforms
FLM Infra sits between carrier number inventory and enterprise applications — handling number provisioning, 1:1 assignment, and real-time inbound SMS delivery via webhook across US and UK markets.
Infrastructure Model
A direct integration path from carrier number supply to enterprise application delivery.
Platform Capabilities
Dedicated Number Provisioning
Allocate and manage mobile numbers with full lifecycle control — from acquisition through retirement.
US & UK Number Coverage
Geographic coverage across United States and United Kingdom with direct carrier sourcing.
Real-Time Inbound SMS Ingestion
Low-latency inbound SMS processing with immediate structured delivery to configured endpoints — no polling required.
Webhook Delivery System
Event-driven delivery to customer-defined HTTPS endpoints with retry guarantees and delivery logs.
API-First Integration
REST API layer for number management, assignment configuration, and delivery status queries.
Lifecycle & Assignment Management
Full visibility into number state, assignment history, and delivery logs — auditable records across your entire number fleet.
Inbound SMS Delivery via Webhook
When an inbound SMS arrives on a provisioned number, the payload is dispatched immediately to a customer-configured HTTPS endpoint. No polling. No queuing delay. Messages reach the application layer the moment they hit the network.
Each number is exclusively bound to a single enterprise account — no shared pools, no cross-tenant traffic. Delivery attempts are logged, retried on failure, and queryable via the management API.
- Structured JSON payload dispatched on every inbound SMS
- HTTPS webhook with configurable retry on delivery failure
- Exclusive 1:1 number-to-account binding — no shared pools
- Per-event delivery receipts and full audit log
{ "number": "+44780XXXXXX", "from": "+14155XXXXXX", "message": "Appointment confirmed for Tue 14:00", "timestamp": "2026-01-01T12:00:04Z" }
Payload schema is stable and versioned. Delivery triggered within milliseconds of network receipt.
Built for Enterprise Workloads
Designed for enterprise operators who require stable, dedicated inbound number infrastructure — where number persistence, delivery reliability, and programmatic control are non-negotiable.
SaaS Platform Number Provisioning
SaaS providers that allocate a dedicated inbound number to each account, enabling per-tenant SMS receive capability within their platform.
Operational Alerting & Response
Enterprise operations teams using dedicated numbers to receive structured inbound SMS from field systems, devices, or staff.
Appointment & Workflow Confirmation
Platforms that require inbound SMS confirmation responses tied to a stable, long-term number identity per workflow or location.
Internal Enterprise Tooling
Enterprises embedding programmable inbound SMS into internal tools — HR systems, IT helpdesks, scheduling platforms — via API.
Managed Number Infrastructure
Organisations requiring programmatic control over a mobile number fleet — provisioning, assignment, and lifecycle — at scale.
Built for Carrier-Level Scrutiny
We understand that carriers and MVNOs are accountable for traffic on their networks. Our operational and legal commitments are designed to meet that standard.
TCPA Compliance
Operations are conducted in adherence with TCPA requirements. Number usage is strictly limited to lawful enterprise inbound SMS workloads.
Abuse & Spam Monitoring
Active traffic monitoring is in place to detect and prevent misuse — including spam, fraud, and unsolicited messaging.
No Grey Routes
All number provisioning and SMS traffic flows through legitimate carrier and MVNO channels. No SIM farms, no grey-route termination, no traffic arbitrage. Clean, auditable traffic from source to delivery.
