AVB VERITAS · EXPERTISE / ANALYSIS / TRUTH
01 / The proposition
Technical depth
that survives scrutiny.
The strongest expert work does more than explain technology. It identifies what the evidence supports, exposes unsupported assumptions, and gives counsel a precise, usable account of what happened.
Leo brings the perspective of a founder, licensed telecom operator, network architect, corporate executive, and legal-technical strategist. His work is grounded in operational reality—not theory alone.
02 / Areas of expertise
Selected domains
Where law meets
technical reality.
Focused support for disputes in which network behavior, regulatory obligations, digital evidence, or software architecture determines the outcome.
↗
Network & interconnection evidence
VoIP and SMS routing, number portability, ENUM, SIP, SMPP, SS7/SCCP, signaling traces, delivery paths, service interruptions, and operator disputes.
Cybersecurity & data breach
Forensic records, intrusion timelines, authentication and access controls, vulnerability and patch history, incident response, vendor compromise, and preventability.
AI, software & intellectual property
AI-generated content, training data, software ownership, open-source dependencies, licensing, model documentation, repositories, workflows, and human contribution.
Privacy, data protection & M&A
GDPR, data residency, cross-border processing, technical privacy claims, and legal-technical due diligence for telecom, software, AI, and data-heavy transactions.

- 02Test the record
Analyze filings, logs, traffic records, configurations, contracts, code, policies, and technical assertions against operational reality.
- 03Make it usable
Translate findings into advisory or expert reports, discovery and hearing support, deposition preparation, testimony, or clear presentation before a court, tribunal, or arbitral panel.
04 / Questions that matter
Counsel needs
a defensible answer.
Did the company act reasonably?01
Was the breach preventable?02
Was the traceback response adequate?03
Which party was technically responsible?04
Does the claimed intellectual property exist?05
Do the allegations match the technical evidence?06
05 / Selected matters
Experience where
the rules were tested.
Representative public matters involving telecommunications companies led by Leo Herps. Links open the underlying regulator, court-reporting, or institutional source.
SMS interoperability and wholesale tariff dispute
RGTN asked the Dutch Authority for Consumers and Markets to address access to its 0970 numbers and the wholesale terms for SMS delivery. ACM found the parties’ proposals impeded interoperability and set a €0.003 termination rate per SMS.
Accessibility of 084/087 numbers and service remuneration
In a formal dispute brought by Redworks, ACM required KPN to make Redworks’ 084/087 numbers accessible. The decision also delineated regulated call termination from the separate follow-on service; that distinction was later upheld on appeal.
Judicial review of denied number allocation
A Dutch court instructed ACM to reassess RGTN’s number-allocation application, returning the regulatory decision for renewed consideration.
Published case note ↗Federal authorization for direct access to U.S. numbering
RGTN USA pursued an interconnected VoIP numbering authorization under 47 C.F.R. § 52.15(g). Following a non-streamlined review—including Executive Branch assessment of the company’s foreign ownership—the FCC granted authority to obtain North American Numbering Plan resources directly from the Numbering Administrator.
International telecommunications authority
Following foreign-ownership review, the FCC granted RGTN USA international Section 214 authority to provide global resale telecommunications services. The published record reports that the reviewing Executive Branch committee had no objection to the grant at that time.
California telephone corporation registration
The California Public Utilities Commission granted RGTN USA a statewide registration license for non-facilities-based fixed interconnected VoIP service. The Commission found that RGTN satisfied the registration requirements and demonstrated the financial ability and expertise required to operate.
