The old Plantronics CS product line (e.g.: CS70N) requires the APS-1 EHS adapter.
After installing the headset on Mitel telephones, you have to activate DHSG under the telephone’s audio settings and change the audio mode to “Headset/Speaker”. The audio settings for the telephone can be found in the menu (tool key on the telephone) under 2.Presettings / 5.Audio Settings. Restart the telephone.
When using the EHS adapter with Mitel telephones, you cannot use a keypad add-on with the telephone, given that the connection on the telephone is being used for the headset.
To connect Mitel telephones with Sennheiser headsets, ensure that the switches 1 and 4 are activated in the back of the basis. Furthermore ensure that the Sennheiser Firmware is up to date.
