What Unity Connection license to use with CME 14?

[speakip]

Upgraded old CME/CUE 7.0 to CME 14 and looking to integrate it with Unity Connection. Need license recommendations (voicemail and IVR only)

Just buy the "normal" licenses for the Unity.
Unity Connection Basic Messaging User licenses and Unity Connection Enhanced Messaging User licenses. Whatever you need of them.
