The Cisco NME-UMG is a network module for Cisco ISR platforms (e.g., 2800, 2900, 3800 series), serving as a centralized Unified Messaging Gateway that intelligently routes voicemail and directory information between Cisco Unity Express, Cisco Unity, and third-party systems. Designed to simplify voice messaging networks, it replaces full mesh VPIM connectivity with a hub-and-spoke architecture, supporting up to 250 registered nodes (1,000 in the enhanced‑capacity NME‑UMG‑EC variant) and serving as a messaging backbone. The module features a 1 GHz Celeron® M CPU, 1 GB RAM, 80 GB hard disk, a single 1 GbE management port and USB port, and includes module faceplate LEDs and a shutdown button for managed application lifecycle.
