Just an FYI. I had to edit the basefile under the EPM and add
<VoiceService.1.VoiceProfile.1.Line.1.CallingFeatures.MWIEnable>true</VoiceService.1.VoiceProfile.1.Line.1.CallingFeatures.MWIEnable>
<VoiceService.1.VoiceProfile.1.Line.1.CallingFeatures.X_VMWIEnable>true</VoiceService.1.VoiceProfile.1.Line.1.CallingFeatures.X_VMWIEnable>
