You only need an adapter if the phone isn't plugged into a PoE switch. On any desk phone page you can also pick "With power adapter" to get the right one in the same order.

Looking for a headset? See the headsets collection, which also has the EHS adapters and Bluetooth and Wi-Fi dongles.

Common questions

What is an electronic hook switch?

An electronic hook switch (EHS) lets a wireless headset answer and hang up calls on the desk phone, so you don't have to walk back to the desk. The ClearlyIP EHS30 connects Plantronics and Jabra wireless headsets to the Crosstalk 250 and 270.
