From what I read in your post, MWI is working for some users? If this is true, I would check the following for the users having the problem:
1. Make sure the problem IP phones can correctly dial the MWI On and Off extensions you have coded in CallManager. The phones need to be in the correct partition and CSS as the voicemail ports to make this work. I would compare a working IP phone to one that is not.
2. Check the Unity application event log for errors, especially 0X80007005, which are typically permissions related. Are the problem users' mailboxes on an information store for which the Unity permissions wizard was run?
It would help us alot of you actually pasted the word for word errors you see in the applog regarding the mwi failures. Once I see that, I can get a better idea of where to start. Also, what service pack is Exch2k7? I would recommend at least SP1 before going forward. Also, is Exch2k7 clustered or a single server?
