The Avaya J159 IP Phone (Material Code: 700512392) is an enterprise-grade VoIP phone engineered for users who demand advanced call handling, multiple line appearances, and rapid feature access, but have limited physical desk space. Designed with a unique dual-display architecture, the J159 bridges the gap between basic desktop phones and expanded reception consoles by incorporating two distinct color screens directly into its sleek chassis.
The primary 2.8-inch main color display handles call appearance, main menu options, and directory navigation, while a secondary 2.3-inch color display provides dedicated programmable feature keys. Together, they offer 4 physical line keys with dual LEDs (Red/Green) and up to 24 soft/programmable keys across 4 scrolling pages. Built with dual Gigabit Ethernet ports, integrated Power over Ethernet (PoE Class 1), wideband audio (G.722), and full support for both SIP and H.323 protocols, the J159 delivers crystal-clear audio and fast network throughput for Avaya IP Office and Avaya Aura communication platforms.
