Ericsson DBC22501/01001 Dialog 4225 V1 digital telephone in light grey.
The Ericsson DBC225 01/01001, also known as the Dialog 4225, is a digital business telephone designed for enterprise communication environments. This handset provides a user-friendly interface with a clear display and essential call handling features suitable for general office use.
The Dialog 4225 is part of Ericsson’s Dialog 4000 series, designed to operate with Ericsson MD110 and BusinessPhone PBX systems. It serves as a reliable desk phone for everyday business telephony requirements in corporate and institutional settings.
The Dialog 4000 series represents legacy Ericsson enterprise telephony equipment. Following Ericsson’s exit from the enterprise communications market and subsequent transitions through Aastra and Mitel, these handsets remain in use across existing MD110 and BusinessPhone installations where organisations continue to operate their established infrastructure.
