The Avaya IP Office R12 Essential Edition License (Material Code: 383112 / LIC: DS) is the fundamental prerequisite software license required to operate an Avaya IP Office Release 12 system architecture. Bound directly to the system’s System SD Card Dongle ID via the Avaya PLDS portal, this license unlocks the core PBX telephony functionality and system software operations on the IP500 V2 and IP500 V2A control units running firmware version 12.0 or higher.
Serving as the essential foundation for small to medium enterprise communications, the Essential Edition license enables built-in automated attendant (Auto-Attendant) routing, multi-party conference bridging, call hold, transfer, park, and hunt group routing. Furthermore, it unlocks integrated Embedded Voicemail capability (up to 2 to 6 ports), enabling per-user voicemail boxes, customized greetings, and basic mobility features without requiring an external server or separate voicemail hardware card.
