A vendor has porpose adding Nortel Norstar at our remote sites to our CUCM 6.X Using Unity 5.x Voicemail. The Norstar presently uses the Centrex lines with Voicemail. The Centrex lines will be converted to DID and pointed to a PRI, which would elimate there centrex voicemail service.
Is there a method that we can use the Unity Voicemail for the Norstar users?
They have proposed:
1.) connecting the analog ports on the Norstar to a 3845 configured with FXO ports to provide inbound and outbound dialing
