Shop HP Poly CS540A DECT Wireless Headset | TAA Certified | TelQuest International

Key Features

• DECT wireless technology in the 1.9 GHz band for interference‑resistant connectivity and better audio isolation than standard Bluetooth office headsets.      

• Convertible wearing styles, including over‑the‑ear with earloop and over‑the‑head with headband; many deployments can also add an optional behind‑the‑head neckband.      

• Ultra‑lightweight design (well under 1 oz for the headset) to minimize fatigue for agents and knowledge workers on calls all day.      

• Long wireless range, typically up to around 350–400 ft line‑of‑sight from the base, allowing users to roam the office, retrieve documents, or consult colleagues without dropping calls.      

• Battery talk time of up to about 7 hours, supported by an adaptive power system that automatically reduces transmit power when closer to the base to conserve battery and increase density.      

• Noise‑canceling microphone with DSP to reduce background noise and enhance clarity for the far end, making conversations more professional and easier to follow.      

• Acoustic protection technology (SoundGuard‑class) that limits sudden loud sounds to safe levels to help protect hearing during long-term use.      

• Desk phone–centric connectivity via RJ‑11 interface on the base, with optional accessories enabling remote call answer/end.      

• Multi‑headset conferencing support, allowing several CS540A headsets to pair to one base for quick ad‑hoc collaboration.      

• TAA compliant variant designed to meet U.S. Trade Agreements Act requirements for government and public sector procurement.

• Traditional PBX deployment

• CS540A base connects to the RJ‑11 handset port of a digital or analog desk phone.      

• Optional handset lifter or EHS cable provides remote off‑hook control.      

• Ideal when the PBX remains on‑premises and the handset is the main endpoint.

• IP‑PBX with hard phones

• Desk phones (e.g., SIP phones) connect to the LAN; the CS540A base still connects via the handset/phone port.      

• Users keep the same call features (transfer, hold, conference) through phone keys while enjoying wireless audio.

• Hybrid UC environments

• Where softphones and desk phones coexist, CS540A serves as the desk phone wireless endpoint, while a separate USB headset or speakerphone handles PC‑based calls.      

• Especially useful for users who still receive critical calls on legacy lines.

• Accessory Recommendations

  Electronic Hook Switch (EHS) cable: For your specific phone brand (e.g., Cisco, Avaya, Poly), to enable remote answer/end and hook control directly from the headset button.      

• HL10 handset lifter: For desk phones that do not support EHS; physically lifts the handset when you press the call button, enabling remote answer.      

• Neckband / behind‑the‑head band: Optional accessory for users who prefer not to wear a headband over their hair or who want maximum stability.      

• Spare battery (if applicable) and charging accessories: Useful for multi‑shift operations where back‑to‑back users share a base and need minimal downtime between charges.      

• Replacement ear tips and cushions: Keeping spares on hand improves hygiene and comfort over time, especially in shared‑headset environments.

• Use‑Case Scenarios

  Contact centers and helpdesks: Agents handling back‑to‑back calls all day benefit from comfort, noise cancelation and the ability to move freely to access files or consult supervisors.      

• Government and public sector offices: TAA certification supports deployments in agencies that require compliant hardware while still demanding enterprise‑class audio quality.      

• Finance and legal offices: Professionals can take calls hands‑free while reviewing documents, typing notes or accessing line‑of‑business applications.      

• Healthcare front desks and scheduling teams: Staff can move between reception, printers and internal offices without dropping calls, improving patient experiences.      

• Executive and manager desks: Leaders who are often on calls can walk their floor or step into an adjoining office while maintaining clear audio and quick call answer/end control.
