Sixteen SIP accounts, a 4.3-inch 480×272 color TFT screen, dual gigabit ethernet with PoE, single USB port, EHS support. The T46G is the previous-generation T46 chassis — superseded by the T46U for new deployments, kept in the catalog for matching existing fleets.
The T46G is the previous generation of the T46 chassis, and for years it was Yealink's best-selling mid-tier phone. The T46U has replaced it for new sales (dual USB, EXP43 sidecar, newer firmware, modern processor), but the T46G is still in active production for the install base — hundreds of thousands of these are in service across North America and Yealink supports them officially.
What it gets right: the 4.3-inch color screen is the same panel as the T46U, the 16-line SIP capacity matches, the keypad feel is identical, and the build is the indestructible T4 chassis. For day-to-day use, you would have a hard time telling the T46G and T46U apart side by side.
What you give up vs. T46U: single USB port instead of dual (so a wireless dongle blocks the headset port), the older EXP40 sidecar instead of the modern EXP43, and a shorter firmware support runway. Yealink will keep the T46G updated through 2027-ish; the T46U has a longer horizon.
Where to buy it instead of the T46U: matching existing T46G deployments. If you have 50 T46Gs and one fails, buying another T46G keeps the spare-parts pool and user training uniform. For any genuinely new deployment, spend the $20-30 more and get the T46U.

Plug the T46G into PoE and ethernet. About a minute later it has registered to your extension. Same auto-provisioning flow as every other supported phone — no SIP credentials to type, no firmware to chase.
Boot, fetch config from our provisioning server, register, ready. About one minute on a normal connection.
16 lines per phone. Each line key has a dual-color LED for status at a glance.
10 line + multi-page 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 T46G. We catch regressions before they reach your fleet.
Tell us how many you need and what extensions to map. We ship pre-configured next business day; you plug them in and they work.
