I resolved this exact [problem this morning for one of my customers.
The problem was that the dialplan-pattern command was prefixing the number. So unity express was looking for extension 153 but was being passed 504053 by the CCME.
What you need to do is the following:
Get into your CCME, go into enable mode, and enter the command "debug ccsip all"
This will give you a warning re: service disruption. Unless you are using Sip for all of your IP phones, ignore this and proceed by pressing enter. Now enter "term mon" and start a session log as you will get a lot of output.
Once youve done this, make a call to an extension, let it go to voicemail - then open up the resultant log file. This is what the bit i was interested in looked like in my file:

The "Diversion" part at the bottom of what ive pasted is what you are interested in.
What i did to get around this was create a translation rule:
Voice translation-rule 1
rule 1 /5840../ /1../
voice translation-profile VM_Redirect
translate redirect-target 1
translate redirect-something else 1
translate calling 1
dial peer voice 6000 pots
destination pattern 80..
translation profile outgoing VM_Redirect
Apologies for the "translate-something else" i cant remember what it was. Question mark it and its obvious.
The translate redirects translate the "diversion" number so CUE recognises it when it comes in. The translate calling translates the calling number so CUE recognises the users when they pick up their messages (As the dial-plan pattern is applied even when the IP phones call the CUE)
Hope this helps! Please excuse any syntax errors etc as thats typed from memory.
Thanks
