Product information

Description

The Avaya J159 IP Phone is a professional communication device designed for business environments, offering reliable performance and high-definition audio quality. Featuring a compact form factor in black, it includes a wired handset, a 3.5-inch LED display with 320 x 240 pixel resolution, and primary and secondary color displays to streamline daily operations. This VoIP phone supports multiple voice codecs including OPUS, G.722, G.711, G.726, and G.729, ensuring clear and understandable multi-party calls. With integrated Gigabit Ethernet, Power over Ethernet (PoE) support, built-in speakerphone capabilities, and optional Wi-Fi connectivity via the J100 Wireless Module, the Avaya J159 delivers flexible network integration and efficient call handling for headquarters, remote locations, or home offices.

Advantages

The Avaya J159 IP Phone enhances daily office productivity through its high-definition audio quality in both the handset and headset, which helps reduce user fatigue during long conversations. It features 10 dual-color red and green LED buttons that provide clear visual cues to speed up task management, alongside fixed keys for essential functions such as hold, transfer, conference, and redial. The device improves network flexibility by including a secondary Gigabit Ethernet port for a PC connection. For accessibility, the wired handset includes a built-in volume boost designed for hearing-impaired users. Additionally, the Power-over-Ethernet Class 1 design incorporates a sleep mode to support reduced energy consumption and lower operational costs.

Suitable for

  • Daily business voice communications in corporate offices and enterprise environments
  • Remote workers and home offices requiring reliable network integration
  • Users needing a compact desktop IP phone with multiple feature buttons
  • Organizations utilizing Session Initiation Protocol (SIP) and Avaya communication platforms

When it may not be suitable

This IP phone may not be suitable for users who require a fully wireless desktop communication device without any wired connections, as the handset is wired and network setup typically relies on Ethernet cabling unless the optional wireless module is utilized. It is also not designed for environments that require basic analog telephony without IP network infrastructure.

Key specifications

  • IP Phone product type in black color
  • Wired handset with built-in volume boost for hearing impaired
  • 3.5-inch LED display with 320 x 240 pixel resolution
  • Support for G.711, G.722, G.726, G.729, G.729A, G.729B, and OPUS voice codecs
  • Gigabit Ethernet LAN interface supporting 10, 100, and 1000 Mbit/s data rates with a secondary port for PC pass-through
  • Power over Ethernet (PoE) Class 1 support
  • Integrated speakerphone and fixed keys for call management
  • 10 dual-color red and green LED buttons

How to use

To set up the Avaya J159 IP Phone, connect the device to your local area network using an Ethernet cable via the primary Gigabit Ethernet port, or utilize Power over Ethernet (PoE) to supply both data and electrical power through a single cable. If PoE is not available, connect the appropriate power adapter to the input voltage port. Adjust the desk stand to your preferred viewing angle and plug the wired handset into the designated port. Once powered on, the device connects to your enterprise IP network and configures automatically through your supported communication platform. Use the 3.5-inch LED display, softkeys, and fixed navigation buttons to manage calls, adjust speakerphone settings, and access directory functions.

What to consider before purchase

  • Compatibility with your existing enterprise telephony platforms such as Avaya Aura or IP Office
  • Availability of Power over Ethernet (PoE) infrastructure or a compatible 5V power adapter
  • Network requirements, including whether Gigabit Ethernet cabling or the optional Wi-Fi module is preferred
  • Desk space availability for a compact IP phone featuring a 3.5-inch display and multiple function buttons

For optimal performance and energy efficiency, ensure the device is connected to a compatible PoE-enabled switch and update the firmware regularly through your IT administrator to maintain secure and stable enterprise communications.
