Cisco Unified messaging with Lotus Notes

We are running Cisco VOIP in a Unified Messaging enviornment with Lotus Notes for voicemail. If I open up a person document for someone who is using this Unified Messaging, there is an attachment called CSUnity Voicename. Does anyone know what this is and what it is used for? I am trying to get a photo to work with Sametime and I believe this attachment is screwing up my plans. I was successful in adding the photo to someone who isn’t using the Unifed Messagin, but when I try to add the photo or attribute to be more precise to myself, I get an error.

Joseph, I believe this is where the user’s personal greeting is stored. You probably don’t want to remove it.
