What should I know about Mitel's AAstra Hookswitch for Plantronics Headsets?

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:

6737i

6735i

6757i

6755i

6753i

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
