Explanation

IAD (Integrated Access Device) is the bridge that converts analog voice signals from traditional phones into IP packets, enabling legacy analog endpoints to register with the U1900 unified gateway and communicate over an IP network. Without this conversion device, analog phones - which have no native IP capability - cannot participate in a VoIP-based UC environment.

AppAgent is a software component used for application-layer management and feature delivery within eSpace, not a hardware interface for analog connectivity. eSight is Huawei's network management platform used to monitor and configure network devices - it plays an administrative role, not a signal-conversion role. CDR (Call Detail Record) is simply a log file that records call metadata (duration, parties, time); it has nothing to do with how a phone accesses a network.

Memory tip: Think of IAD = "I Adapt analog to Digital/IP" - it's the translator sitting between the old analog world and the new IP network, the only option here that is a physical access device rather than software or a data record.
