DBC187 01/01001 Ericsson Dialog 4000 Series Digital Telephone

The Ericsson DBC187 01/01001 is the Dialog 4187, a digital system telephone designed for use with Ericsson’s MD110 and BusinessPhone communication platforms. This handset provides voice communication capabilities with an integrated display and function keys for efficient call handling in business environments.

The Dialog 4187 was part of Ericsson’s Dialog 4000 series, developed for enterprise telephony deployments requiring reliable, feature-rich desk phones. It connects via digital trunk interfaces to Ericsson PBX systems, supporting features such as call transfer, conferencing, and programmable keys.

This is a legacy product from Ericsson’s enterprise communication portfolio, which has since transitioned through various ownership changes. The Dialog 4000 series remains in use across installed bases where MD110 or BusinessPhone systems continue to operate, making replacement units valuable for maintenance purposes.
