DBC42002/02001 AASTRA Dialog 4000 Series SIP Handset

The AASTRA DBC42002/02001 is a Dialog 4420 IP Basic telephone in Dark Grey finish. This is an entry-level IP desk phone designed for users requiring straightforward voice communication without advanced feature requirements. The Dialog 4420 IP Basic provides essential telephony functions in a compact, professional handset format.

The Dialog 4420 IP Basic is part of the Aastra Dialog 4000 series, developed for use with Ericsson/Aastra MD110 and MX-ONE communication platforms. These IP endpoints deliver SIP-based voice connectivity within enterprise telephony environments, offering a migration path from traditional TDM infrastructure to IP-based communications.

This handset represents legacy Aastra/Ericsson telephony technology. Following Mitel’s acquisition of Aastra, the Dialog 4000 series has been superseded by newer platforms, though existing MD110 and MX-ONE deployments continue to support these endpoints. The Dark Grey colour variant suits professional office environments.
