Ericsson DBC220 01/01001 Dialog 4220 digital telephone for BusinessPhone and MD110 systems.
The Ericsson DBC220 01/01001, also known as the Dialog 4220, is a digital business telephone designed for use with Ericsson enterprise communication systems. This handset provides essential voice communication features in a compact, user-friendly design suitable for everyday office use.
The Dialog 4220 is part of the Dialog 4000 series and is designed for deployment with Ericsson BusinessPhone and MD110 PBX platforms. It serves as a standard desk phone for users who require reliable voice communication without advanced features, making it well-suited for general office environments, reception areas, and common spaces.
This is a legacy product from Ericsson’s enterprise telephony portfolio, which has since transitioned under Mitel following acquisition. Despite being discontinued, the Dialog 4220 remains in active use across many existing BusinessPhone and MD110 installations where organisations continue to maintain their established infrastructure.
