The following guide shows how to connect a Plantronics CS520 (This will also apply to the other headsets in the CS500 series) headset to the Mitel 6865i desk phone to allow EHS functionality (the making and hanging up of calls via the headset button).
As well as the CS520 headset and the 6865i phone you will also need a Plantronics APS-11 EHS Cable.
1) Connect the APS-11 cable to the back of the CS520 stand, using the end of the cable that has both an RJ45 connector and a 3.5mm jack connector. Both connectors should be plugged in to the respective ports on the back of the stand.
2) Plug the other end of the APS-11 cable into the RJ45 socket on the back of the Mitel phone, you will need to remove the plastic spacer clip from the socket on the phone in order for it to fit. Please refer to the user manual for help with this.
3) Finally, you need to change some settings on the Mitel phone to enable the EHS functionality. Make the following changes via the menu on the handset itself (press the button with the gear icon to open the menu):
i) Go to Preferences – Set Audio – Audio Mode. Select Headset from the list and press the tick button to confirm.
ii) Go to Preferences – Set Audio – DHSG. Select the “DHSG is On” option and press the tick button to confirm.
That’s it! The headset should now be able to make and receive calls using the EHS functionality.
