## Long description

The HP Poly APP-51 Electronic Hookswitch by PLANTRONICS is a TAA-compliant accessory designed to provide electronic call answer and end control for compatible desk phones and headset systems. Manufactured in Mexico, this device integrates into supported telephony setups to enable remote hookswitch functionality, allowing users to answer or end calls from their headset without manually lifting the handset or pressing phone buttons.
Advantages
The HP Poly APP-51 offers reliable remote hookswitch operation that reduces the need to interact directly with the desk phone during calls. Its TAA compliance makes it suitable for environments with procurement requirements, and its compatibility with supported PLANTRONICS systems ensures coordinated behavior between headset and phone. The compact form factor and straightforward connection points allow integration into standard office and contact center installations.
Suitable for
Office workstations where hands-free call control is needed
Contact centers requiring consistent headset-to-phone call handling
Environments with TAA procurement or compliance requirements
Desk phone setups that support electronic hookswitch accessories
When it may not be suitable
This electronic hookswitch is intended for use only with desk phones and headset systems that explicitly support Plantronics hookswitch accessories; it will not function with incompatible telephony equipment. It does not replace a headset or phone and does not add features beyond remote answer/end hookswitch control.
Key specifications
Function: electronic hookswitch for remote answer/end call control
Compliance: TAA-compliant product
Compatibility: designed for supported desk phones and PLANTRONICS headset systems
Origin: manufactured in Mexico
Form factor: compact inline accessory for desk phone integration
How to use
Install the HP Poly APP-51 by connecting it between the headset and the compatible desk phone according to the phone and headset manufacturer instructions. Once connected and configured with supported devices, use the headset controls to answer and end calls electronically; the accessory communicates hookswitch commands to the phone so the user can manage calls without touching the handset. Follow any setup prompts or configuration steps specified in the phone or headset documentation to ensure correct operation.
What to consider before purchase
Confirm that your desk phone model and headset system explicitly support Plantronics electronic hookswitch accessories.
Check procurement requirements if TAA compliance is required for your organization.
Ensure physical connection points and cabling in your workspace allow integration of an inline accessory.
Usage recommendations
Verify compatibility with your specific desk phone firmware and headset model before installation, and follow the vendor setup guide to enable hookswitch functionality. For multi-user or contact center deployments, test one unit first to confirm expected behavior with your telephony platform.
