Activetelco — 00:01:DC (MA-L)

Activetelco holds a single MA-L block, 00:01:DC, registered to a Fremont, California address. Unlike a bare shell registration, secondary sources corroborate an identifiable operating company behind the prefix: ActiveTelco Inc. built next-generation IP-telephony and unified-messaging platforms for telecom service providers — unified messaging, long-distance routing, voicemail/fax delivery, call forwarding, conferencing, and callback — sold into carrier networks rather than to consumers. The company did not remain independent: Tut Systems acquired ActiveTelco around December 2000/January 2001 for roughly $2.9 million in stock plus assumed debt and liabilities, intending to fold the technology into its IntelliPOP multi-service access platform. Two independent trade-press write-ups (Lightreading and GlobeSt) corroborate the acquisition and product line, which is why this entry clears the single-OUI shell bar despite holding only one registered prefix. Corporate incorporation/dissolution dates surfaced in a search-engine snippet from a third-party company-registry aggregator but could not be confirmed by direct fetch (blocked with HTTP 403), so those specific dates are held at low confidence and are NOT IEEE-sourced facts.

Analyst note

This is a single-OUI registrant, but unlike a bare shell it carries verifiable company substance — an identifiable, named company with a specific carrier-telephony product line and a documented acquisition — so it clears the abstention bar for finalization; only the fine-grained incorporation/dissolution dates remain unconfirmed.
