The Aastra DBY42001/1 is an option unit designed to extend the functionality of Dialog 4222, 4225 and 4425 series digital telephones. This expansion module provides additional capabilities to enhance the base telephone’s feature set within Ericsson/Aastra PBX environments.
The Dialog 4222, 4225 and 4425 handsets were widely deployed on Ericsson MD110 and BusinessPhone platforms, serving as reliable digital endpoints for enterprise telephony. Option units such as the DBY42001/1 allowed organisations to customise handset functionality according to specific user requirements.
This is a legacy product from the Ericsson/Aastra Dialog range, which has since been superseded by newer Mitel platforms following the Aastra-Mitel merger. It remains relevant for organisations maintaining existing MD110 or BusinessPhone installations where Dialog handsets are still in active service.
