Headset setup instruction for using EHS cable with Aastra Phones - 6753i, 6755i, 6757i, and 6757i

What is required to use EHS (electronic hook switch) with my Aastra phone ( 6753i, 6755i, 6757i, and 6757i)?

Many users find it useful to use EHS - Electronic Hook Switch for answering calls through the wireless headset rather then the older mechanical "lifters". When using the following Aastra phones: 6753i, 6755i, 6757i, and 6757i you need to enable DHSG settings on both the wireless headset as well as the Aastra phone.  You will also need the correct DHSG cables.  We provide a kit for both Plantronics DHSG and Jabra DHSG wireless headsets

Note: For Jabra wireless headset you will need to configure the Remote Call control to "DHSG".  The default mode is "auto".DHSG_cable_for_plantronics_aastra
