Yealink T41S

Why the T41S is on the catalog.

The T41S is the practical working-desk phone of the T4 mid tier. Six SIP lines covers any realistic small-business need. The 27 multi-page programmable keys give you serious BLF capacity. The USB port means you can plug in a wired Yealink, Jabra, or Plantronics headset and have clean two-channel audio. EHS support means a wireless headset answers calls from its own controls. For an agent who spends six hours a day on the phone, this matters.

Where it lands against the T41P: $20 more for gigabit ethernet, USB headset, Opus codec, and a longer firmware track. There is no scenario where the T41P is the better buy for a new desk — the T41S wins on every meaningful spec.

Where it lands against the T41U: $20 less than the T41U, which adds a second USB port. If you need to run both a wired USB headset and a Wi-Fi / Bluetooth dongle simultaneously, the T41U is required. For most agents who pick one or the other, the T41S is enough.

Where it lands against the T46G: $10 less, but you give up the 4.3-inch color screen and ten extra SIP lines. For a phone that lives on a desk all day, the screen upgrade alone is usually worth $10. The T41S is the right pick for monochrome-tolerant agents who care more about the USB headset port than the screen.
