Avaya 700458540 P-series/Cajun switching and IP Office telephony Digital Telephone

The Avaya 700458540 is an Avaya 1616-I IP Deskphone shipped with firmware 1.3.4d. The 1616 is a mid-range six-line-appearance phone in Avaya’s 1600 series, built for Avaya IP Office and Communication Manager environments, with a 3-line greyscale display, integrated Ethernet switch port for a daisy-chained PC, and support for a range of button-module expansions. It uses the same H.323-based signalling as the rest of the 1600 range, so it drops into an existing 1600-series deployment without any change to dial plan or call features. Genuine handsets of this kind are a routine requirement for desk moves, adds and changes on established Avaya telephony estates. Tech-Star (UK-based, shipped worldwide) supplies Avaya components for ongoing network maintenance.
