Single-line SIP phone for small offices

The Avaya J129 is a single-line SIP phone built for small-office VoIP deployments. It runs on Power over Ethernet 802.3 af and includes dual 10/100 ports so a co-located PC can share the network drop. The handset offers a built-in volume boost for hearing-impaired compatibility.

Plug into PoE and configure the SIP server

Connect the phone to a PoE-enabled switch or use an optional 802.3 af injector if the switch does not supply power. The 128 x 32 pixel monochrome display and three context-sensitive soft keys guide basic provisioning. A common issue is forgetting to enable OPUS, G.711, G.722, G.726A or G.729 codecs on the server side, which causes one-way audio.

Verify PBX compatibility and network infrastructure

Ensure the PBX runs Avaya Aura, IP Office 10.0 SP2 or higher, Broadsoft Broadworks R21SP1 or Zang Office R 1.0 for native feature support. The link speed is limited to 10/100, so Gigabit-only cabling plans will not improve throughput. Buyers who need multiple line appearances or colour displays should consider other models.

Questions about this item

How can I confirm the Avaya J129 IP Phone is working after connecting it to the network?

The 128 x 32 pixel monochrome display will light up and show the line status, while the handset provides dial tone; you can also place a test call to verify the OPUS Codec and G.711a/u audio paths are active.

What comes with the Avaya J129 IP Phone and what must I purchase separately?

The box contains the phone unit, handset and coiled cord; a PoE injector is not included and must be bought separately if your network switch does not supply Power over Ethernet 802.3 af.

Which SIP platform version should I select for the Avaya J129 IP Phone in my environment?

Choose Avaya Aura for AST-SIP enhanced features, Avaya IP Office 10.0 SP2 or higher for native support, Broadsoft Broadworks R21SP1, or Zang Office R 1.0 depending on your call server.
