Poly Setup notes from Poly

This headset connects to desk phones over its DECT base — remote answer requires the EHS cable listed per phone above.
Where the exact EHS cable is not yet confirmed for your phone, the pairing shows an "ask an advisor" state rather than a guessed part.
Call-control level is shown per phone; where a manufacturer did not publish it, the badge is omitted rather than shown as audio-only.

Poly CS540A DECT 1880-1900 MHz Headset

Professional wireless headset. Works with every phone above. Just choose the exact EHS cable required for full remote call control.
