Sixteen SIP accounts, a 4.3-inch 480×272 color screen, dual gigabit ethernet with PoE, integrated dual-band Wi-Fi 6 and Bluetooth 4.2, dual USB ports, EHS support. The T54W is what you buy when you want everything good about the T46U plus built-in wireless.
The T54W is the T5 family's volume-seller and the phone we recommend by default for executive desks across the catalog. It is essentially the T46U — same 4.3-inch landscape color screen, same 16 SIP lines, same dual USB, same EHS — with built-in dual-band Wi-Fi 6 and Bluetooth 4.2 added. For $10 over the T46U, the wireless built in is a meaningful upgrade.
Where it lands in a deployment: this is the executive desk phone that does not need anything else. Wi-Fi for hot-desking or relocation flexibility, Bluetooth for direct wireless headset pairing, dual USB for both a wired headset and a separate USB peripheral, sidecar support via EXP43 for assistant-pool BLF monitoring. Almost every executive use case can be answered with a single T54W SKU.
Where to step up: the T57W is $50 more and adds the 7-inch touchscreen, otherwise identical Wi-Fi/BT spec. For C-suite or boardroom phones where presence matters, the bigger screen is worth it. For everyone else — VPs, directors, managers — the T54W's 4.3-inch screen is the better-priced sweet spot.
Where to step down: the T46U is $10 less and gives up Wi-Fi/BT. For permanently-wired desks where wireless will never be used, the T46U saves you the cost. For any desk with even a small chance of needing Wi-Fi, the T54W's flexibility is worth it.
