Part-No: D0062-0011-34-00 (“DHSG CABLE KIT”)
We do not carry this part, this would need to be special ordered.
This part works with Mitel Models:
You also need to enable EHS from the phone setting by pressing the spanner button on the phone ---> selecting Audio---> changing audio as headset/speaker and headset as DHSG.
* Aastra does not recommend using EHS with the expansion module
