Setting The Headset Base Unit Options; Enable Electronic Hookswitch; Change The Headset Mode - Polycom VVX 150 User Manual

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.

Setting the Headset Base Unit Options

Before you connect your headset to your phone and use EHS, you need to set the following options for your
specific headset model:
• For Jabra headsets, change the headset mode to DHSG on the headset base unit. For details, refer to your
headset documentation or contact Jabra support.
• For Plantronics headsets, change the coarse receive level to 3 and the transmit level to B on the headset
base unit. For details, refer to the guide that comes with your headset.
• For Sennheiser headsets, set the first DIP switch labeled 1 (DHSG) to the down position on the back of the
headset base unit. For additional details, see your headset's documentation or contact Sennheiser support.
