Exchange UM integration with Cisco and Lync 2013

Hello all,

 

anybody know if its possible to have a UM DialPlan integrated with both Cisco CCM and Lync 2013 ?

 

The goal would be to have voice mail redirection from the users CCM Desk Phone and Lync softphone to his mailbox.

 

We have been doing some work around this but CCM Phones are redirected to the users voicemail but from Lync we get an error saying that "person you are trying to reach does not have a valid voice mailbox on our system".
