What is an Electronic Hook Switch (EHS)?
An Electronic Hook Switch (EHS) is a cable solution that connects a wireless headset base and a desk phone. An EHS enables call control functionality directly on the headset, eliminating the need for a mechanical handset lifter.
Different phone manufacturers use different cables and EHS protocols, as there is no single standard for an EHS. Refer to the Compatibility Guide to check if your desk phone supports EHS, which EHS cable adapter is required, and the EHS protocol that should be configured.
