Switching to the speakerphone or the handset deactivates Headset Memory Mode.
To reactivate Headset Memory Mode:
» Press the headset key twice.
When you use a headset that supports electronic hookswitch (EHS), you can place, answer, and end calls by
using the controls on your headset. To use EHS, you need a headset that includes a serial control interface in
addition to the standard analog headset jack (RJ-9) interface. The serial control interface requires an EHS
adapter that you can purchase from your headset manufacturer.
Headsets that support EHS include a base unit that connects to your phone. The headset connects to the base
unit wirelessly, which enables you to use your headset even if you're some distance away from your phone.
Typically, you can work wirelessly up to 300 feet (91 meters) from your phone and still use the EHS controls.
Check with your headset's user guide for the precise range restrictions.
