Hands-on technical advisory and engineering leadership for enterprise communications platforms, contact centers, and voice infrastructure operators. Specializing in bridging carrier-grade SIP routing with real-time conversational AI, neural audio pipelines, and telecom margin optimization.
Targeted architectural interventions and advisory engagements covering modern conversational AI voice infrastructure, carrier routing, and high-concurrency communications systems.
Engineering low-latency bridges connecting live SIP RTP audio streams to modern LLMs and neural speech engines. Sub-second turn-around times, asynchronous Go/ESL socket handlers, WebSockets audio streaming, and neural Answer Machine Detection (AMD).
Architecture and tuning of high-volume SIP proxies (OpenSIPS, Kamailio) and Session Border Controllers. Engineering multi-carrier failover engines, sub-millisecond route calculations, branch ended telemetry, and dialog state tracking.
Architecting streaming analytical backbones for real-time CDR inspection. Deploying ClickHouse column-stores and Kafka streaming to run automated anomaly detection, real-time carrier margin tracking, and automated route rerouting based on telemetry degradation.
Carrier cost reduction strategies through algorithmic Least Cost Routing (LCR) and local routing number (LRN) dip optimization. Maximizing call completion margins while strictly maintaining quality of service (ASR, PDD, MOS).
End-to-end attestation lifecycle management, Robocall Mitigation Database (RMD) compliance, and carrier reputation protection. Minimizing false-positive 'Spam Likely' labeling to protect delivery rates for critical enterprise calls.
Defensive technical infrastructure and compliance auditing for enterprise contact centers and outbound platforms facing TCPA litigation, FCC inquiries, and state-level regulatory scrutiny (including California Mini-TCPA statutes). Engineering immutable consent audit trails and dialer pacing controls to defeat class-action claims.
Advisory consulting grounded in practical technical collaboration with federal law enforcement agencies (including the United States Department of Justice, the FBI, and the FTC) to combat illegal telecommunications fraud rings, caller ID spoofing, and malicious VoIP syndicates. Helping legitimate carriers and enterprises audit network traffic to resolve federal traceback inquiries swiftly.
Executive technical coaching for telecom founders, CTOs, and voice infrastructure leads. 1-on-1 architecture stress-testing, SIP troubleshooting mentoring, and guidance on transitioning traditional telephony stacks into AI-enabled platforms.
Disciplined diagnostics, quantifiable latency & economic outcomes, and lasting architectural capability.
Comprehensive inspection of active SIP ladders, carrier interconnects, speech-to-text latencies, proxy memory utilization, and CDR data flows to pinpoint bottlenecks and revenue leakage.
Direct implementation and collaborative pairing on mission-critical changes: proxy cluster tuning, real-time voice AI socket gateways, database offloading, and automated carrier route re-balancing.
Ongoing retained advisory for engineering leadership, carrier dispute arbitration, tier-1 vendor evaluations, and proactive capacity planning as call and AI agent volume multiplies.
In-depth technical and regulatory analysis covering federal enforcement actions, statutory boundaries, TCPA jurisprudence, and carrier-grade compliance architecture.
For nearly four decades, the Federal Trade Commission extracted billions in unlawful monetary relief under Section 13(b) without statutory authority. A granular breakdown of the Supreme Court's unanimous decision in AMG Capital Management v. FTC, the historical judicial overreach, and the implications for modern enterprise regulatory defense.
Brian Colombana is an independent telecommunications systems architect, TCPA defense consultant, and regulatory technical advisor. Combining decades of hands-on carrier VoIP architecture with high-stakes regulatory insight, he advises enterprise outbound organizations, contact centers, and telecom platforms on TCPA litigation defense, FTC robocall mitigation rules, and state-level compliance frameworks (including California consumer protection and telephony mandates). Brian has also provided specialized telecommunications consulting to federal law enforcement and regulatory agencies—including the United States Department of Justice (DOJ) and the Federal Bureau of Investigation (FBI)—to dissect fraudulent telephony networks, trace illicit caller-ID spoofing syndicates, and shut down international phone scams.
Having navigated complex regulatory environments and administrative enforcement landscapes in California and nationally, Brian brings a battle-tested understanding of regulatory inquiries, FTC / FCC enforcement mechanisms, and plaintiffs-bar litigation tactics under the TCPA. He works directly with executive leadership, general counsel, and litigation defense teams to provide technical clarity, compliance proof, and expert witness diagnostics that protect businesses from catastrophic liability.
Based between North and South America, Brian delivers advisory consultations and technical engineering coaching in both English and Spanish.
