Electronic Hookswitch Cable for Desk Phones

The HP 85Q59AA connects compatible headsets to desk phones, enabling remote call answering and ending without a mechanical handset lifter. It is designed for office professionals who need hands-free control over their phone system. The cable carries hookswitch signals between the headset base and the telephone.

TAA Compliant for Government Procurement

This cable meets Trade Agreements Act requirements, making it eligible for federal and state purchasing contracts in the United States. Buyers who do not need TAA compliance gain no functional advantage from this specific part number.

Connects Headset Base to Supported Desk Phone

The cable plugs into the headset base station and the handset or headset port of a compatible desk phone. It eliminates the need for a physical lifter mechanism on the telephone. Compatibility depends on the specific phone model and headset system; verify both before purchasing.
