What it is

The T42S is a business desk phone with up to twelve phone lines, a backlit black-and-white screen, programmable keys and gigabit network ports. It has a USB port for an optional headset or wireless adapter. It's part of Yealink's T4S series, the generation before the current T5 phones.

Why you'd want it

• Handles a busy desk: hold, transfer and juggle several calls at once.
• Fast for your computer: gigabit pass-through keeps the PC behind it at full speed.
• Clear calls: HD Voice and a full-duplex speakerphone.
• Room to add: USB port for an optional headset or wireless adapter.

Do you need it?

Choose it for people who take a steady flow of calls: sales, dispatch, office managers. Light users can save with the T41S or T40G. If you want a color screen, look at the T46S; for the current generation with the same job, the T53. This model ships without a power supply: it takes power from your network switch over the network cable (PoE, Power over Ethernet). If your switch doesn't provide PoE, add the Yealink power supply or a PoE injector to your order.

How it works with Plan V

One phone per desk on a Plan V seat. We set it up for your Plan V service before it ships, so it works when you plug it in: your extension, voicemail and line keys ready to go. Add Device Warranty for unlimited replacements.
