One SIP account, a 2.3-inch 132×64 backlit monochrome screen, dual 10/100 ethernet, a 5V power adapter, modern Yealink firmware with Opus. The T30 is the current-generation entry single-line phone — the T19 E2's spiritual successor with a cleaner UI and a longer support window.
The T30 is what Yealink ships now when someone asks for the cheapest current single-line desk phone. It uses the same T3-family chassis as the popular T31 / T33G — same key spacing, same handset feel, same modern UI — but with one SIP line instead of two and no PoE. At $59, it lands in the same price slot as the legacy T19 E2 but with a noticeably nicer screen, newer firmware, and Opus codec support.
Why pick it over the T19 E2: the firmware track. The T19 E2 is a 2014 chassis getting maintenance updates; the T30 is a 2020s chassis still receiving feature improvements. For a deployment you expect to keep for the next eight years, the T30's longer development window matters. The keypad and screen are also genuinely better — caller ID is more readable, menus respond faster, the LED for incoming calls is brighter.
Where to skip it: anywhere PoE is available. Spend $10 more and get the T30P instead — same phone, no wall wart at every desk. The T30 makes sense only when the building has no PoE switches and never will. Also skip it if you need a second line on the same handset — at that point go T31 (no PoE) or T31P (with PoE) for marginal money.

Boot, fetch config from our provisioning server, register, ready. About one minute on a normal connection.
1 line per phone. Each line key has a dual-color LED for status at a glance.
1 line key + 4 soft keys mapped from the voip.army portal — BLF, paging, parking, transfer destinations.
Bringing your own? Send us the MAC, factory-reset, plug in. No charge to add it to the fleet.
Standard PoE — any 802.3af-compliant switch from the last 15 years powers the phone without an adapter.
Tested against every Yealink firmware release for T30. We catch regressions before they reach your fleet.
