I have a vMCD version 8.0 SP2 14.0.2.26 with a NuPoint version 19.0.0.25.
Integration is working. I can leave a user a message and it lights the light. However, when I go off hook and press the flashing envelope key, the call rings to the HCI reroute hunt group. I think i've seen this before and was a simple configuration error, but for the life of me i can't remember what the problem was.
If I reroute the HCI hunt group always to voice mail, pressing the key will then take the user to their mailbox, but I don't think that is the correct resolution!
