Understanding Headset Terminology

Quick Disconnect: Out of the box this is the name of the cord that's on your Aastra/Mitel compatible headset that connects to the direct connect cable.

Direct Connect Cable: This cable connects from your Aastra/Mitel headset to the headset port of your Aastra/Mitel phone.

Electronic Hook Switch: Otherwise known as an EHS cable, this accessory connects from a wireless headset charging base to your Aastra/Mitel phone. Allowing you to answer/end calls when away from your phone.

Handset Lifter: Like an EHS cable, a Handset Lifter also allows you to answer/end calls away from the phone, but physically picks up and hangs up your handset.


How To Use Your Aastra/Mitel Wired Headset

Simply plug the D101, D105 or D200 amplifier into your compatible Discover D700 series wired headset, then plug the other end into your Aastra/Mitel desk phone, into the HEADSET port.
