Hello,

Unable to get the CS540 won't work with a Mitel 6940 phone.

Researching has led me to believe that a APU-76 or APU-75D is needed for the CS540 to work properly.  Is this correct?

What is the different between the APU-76 and the APU-75D?  Which would work best with the Mitel and the CS540?

Thank you..

Hi JaScoMa, a APU-76 is mandatory to make is work. The APU-75 is discontinued and replaced by the APU-76. And the advise is to use the APU-76 in combination with a Mitel 6940 IP phone/

Please note that Mitel does not recommend using EHS with the expansion module.
