Avaya Partner MLS 18D Display Phone 16 Button Black

Business phone with 16 programmable buttons

The Avaya Partner MLS 18D is a wired desk phone designed for offices using Avaya Partner systems. It provides 16 programmable buttons with dual LEDs for line and feature appearances. A built-in 2x16 character display shows caller information and menu prompts. The handset and line cord are included for immediate connection.

Full duplex speakerphone for sustained conversations

The full duplex speakerphone allows hands-free operation where both parties speak and hear simultaneously without clipping. A dedicated speaker button activates the microphone and speaker for conference calls or long holds. Message waiting light provides a visual cue for voicemail during busy periods. The handset remains available for private calls when needed.

Replaces basic single-line sets lacking display

Upgrading from a simple analogue handset adds the 16 programmable buttons, dual LED status and the 2x16 display for call handling efficiency. The jump is worth it when staff manage multiple lines, transfer calls frequently or need hands-free conferencing. It is not for environments that require VoIP protocols or SIP registration unsupported by the Partner platform.
