Telecommunications & Messaging Engineering
An engineering studio

Software for the layer beneath the dial tone.

We design and operate telecommunications and messaging applications for carrier services — real-time observability, wholesale voice, contact-center floors, number lifecycle, and message delivery. Quiet infrastructure for the people who run the lines.

Most of our work ships under someone else’s brand. We don’t advertise the products. We answer email.

What we build

Nine working disciplines, one practice.

Each line below is a body of production code we own, operate, or license to operators. Names are intentionally absent — what matters is what they do.

01

Carrier observability & fraud-detection suite

False-answer supervisionFraud signaturesCall-stretchLoop & bypassMedia qualityPost-dial latencySIP-flow anomalyCarrier CRMMulti-brand ticketing

Our flagship platform — a real-time observability layer watching every CDR, SIP flow, and media stream a carrier network produces. Purpose-built detection engines surface false-answer supervision, fraud signatures, call-stretching schemes, loop and bypass routing, media-quality drops, post-dial latency, and SIP anomalies. Detections feed a multi-brand ticketing workflow and a carrier-grade CRM with SLA timers, vendor scorecards, and AI-assisted email handling.

02

Wholesale voice infrastructure

SIP terminationLCR routingSTIR/SHAKENEdge clusters

Carrier-grade voice planes with quality-weighted least-cost routing, attestation, and redundant edge nodes engineered for sub-second failover and lawful interception.

03

Multi-tenant operations portals

DistributorsResellersBilling recon520+ management tools

Control planes for softswitches that give upstream operators, distributors, and resellers the visibility, provisioning, and guardrails they need — hundreds of management tools exposed through web, mobile, and AI clients on a single tenant-safe surface.

04

Modern interfaces for legacy dialers

Real-time floorTenant isolationAdmin ops

A new generation of administrative consoles that retire aging contact-center back ends while preserving every operational primitive — campaigns, supervision, audit, and recordings.

05

Cloud-native dialing platforms

PredictivePowerPress-1BroadcastCompliance pacing

Predictive, power, preview, press-one, and broadcast modes built ground-up with FTC- and TCPA-compliant pacing, abandonment controls, and emergency throttling baked into the engine.

06

Number-lifecycle middleware

OrderingPortingE911CNAMSupplier reconciliation

End-to-end orchestration for telephone numbers — ordering across carriers, port-in/out state machines, registry compliance, supplier reconciliation, and downstream invoicing.

07

Agent-protocol connectors for switches

MCP serversHundreds of toolsTenant-safe

Model Context Protocol layers that expose operator tooling to large language models without leaking tenant boundaries — so operators can talk to their own infrastructure in plain language.

08

SIP proxy reference deployments

KamailioRTPEngineTLS / SRTPTopology hiding

Gold-standard configurations for high-volume SIP edges: dispatcher failover, NAT traversal, encryption, header manipulation, and HEP-based observability across clusters.

09

A2P messaging gateways

SMPPHTTPDLR trackingAggregator routing

Open-source SMS infrastructure for transactional traffic, OTPs, and notifications — with delivery-receipt tracking, route filters, and aggregator orchestration under sustained load.

How we work

Small team, long-running systems.

Practice 01 — Operations first

The system has to keep working at 3 a.m.

We design for the night shift. Health endpoints, idempotent tasks, structured logs, replayable queues, and quiet failovers — the parts a customer never sees if we’ve done our job.

Practice 02 — Carrier discipline

Every minute is a CDR somewhere.

We treat call-detail records, rate decks, and billing reconcilia­ tion as primary artifacts — not afterthoughts. Margins live or die in those files.

Practice 03 — Boring on purpose

We pick technology that ages well.

Postgres, Kamailio, FreeSWITCH, Asterisk, RTPEngine, Django, Next.js. The modern parts wrap stable cores; the stable cores outlive the modern parts.
