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".
Configuring the Aastra Phone
- On the phone go into Options (you may need the admin password)
- Select "Preferences"
- Select "Set Audio"
- Select "DHSG"
- Select "Done"
TIP: When installing the wireless headset try to install the items the following order:
- Configure DHSG settings on phone first
- Install the cables between the phone and wireless base without the power adapter into the base unit
- Connect power last adapter to wireless base unit
- Restart the Aastra phone
- You can now use the wireless headset
