Avaya J189 IP Phone: Elevate Every Conversation, Empower Every Desk
In today’s hybrid workplace, a phone isn’t “just a phone” anymore. It’s a command center for customer interactions, a lifeline to remote teammates, and the heartbeat of mission‑critical workflows. Suppose your current desk phones can’t keep pace with high‑octane collaboration. In that case, it’s time to meet the Avaya J189 IP Phone—a SIP‑based powerhouse engineered for organizations that refuse to compromise on clarity, capacity, or control.
See More, Do More: Dual Displays Built for Multitaskers
The first thing you notice is the bright 800 × 480 px primary display paired with a 240 × 320 px secondary screen—two vibrant canvases that put every feature at your fingertips. Together, they support 96 programmable line and feature buttons, so receptionists, executives, and contact-center agents can juggle calls, hunt groups, and speed dials without a single mis-tap.
Need even more real estate? The secondary screen doubles as the first “expansion module,” and you can add up to two external Avaya J100 Expansion Modules for a truly modular setup that grows alongside your business.
Hear Every Nuance: SuperWideBand Audio
Dropped syllables and background hiss drain productivity. The J189 tackles that problem head‑on with SuperWideBand full‑duplex audio on the speakerphone, handset, and headset ports. Even in an open office, callers sound as close as if they’re across the desk—no more “Could you repeat that?” The handset is ergonomically designed and hearing‑aid compatible, complete with TTD acoustic coupling, to keep every user comfortable and included.
Built for Speed: Gigabit & USB‑C Connectivity
Latency kills call quality, so the J189 ships with dual Gigabit Ethernet ports—one for the phone, one for your laptop or thin client—ensuring high bandwidth and minimal packet loss. Power is equally flexible: run PoE Class 2 or Class 3 straight from the switch, or use an optional 5 V adapter if you prefer localized power redundancy.
Modern accessories plug and play, thanks to onboard USB Type‑A and Type‑C ports—ideal for premium headsets or a quick mobile device top‑up in between meetings.
Capacity Without Complexity
Heavy call traffic? No sweat. Operators can view five call appearances in full‑screen mode or ten in split‑screen mode, switching in a tap. Four contextual soft keys adjust to whatever you’re doing—parking a call, starting a local conference, or scanning contacts—while dedicated hard keys (Messages, Contacts, Recipients, Headsets, Speakers, and more) shorten every workflow. Multi‑color LEDs next to key functions ensure status is obvious at a glance, reducing mistakes during high‑pressure moments.
Engineered for the Long Haul
From its dual‑position desk stand and optional wall mount to its fan‑less design (read: zero moving parts to fail), the J189 is built for a decade of reliable service. Firmware upgrades over the network keep features fresh, while support for the OPUS codec future‑proofs audio against evolving standards.
