I have a customer that is looking to move from their current PBX and Voicemail system below to Cisco CCM and Unity 4.X
"The switch is a NEC NEAX2000 IVS.
The voicemail is NEC America - NEAXMail AD-120 version 2.7"
They are currently configured for UM in AD2003 and Exchange 2003. I know that Unity has its own attributes of "ciscoecsbu.." and should not conflict with the running of the ADSChemaUpdate that Cisco requires. However has anyone else done this or can tell me if the customers voicemail system has its own attributes because I cannot find any documentation to verify.
Thanks in Advance.
