I have a unified messaging system, verion 5 fully integrated with exchange, callmanager version 6.1 and presence 6, when i try to integrate the CUPC client to retrieve messages from voicemail it says unable to connect to server, i notice the port 143 for IMAP, can anybody confirm this should work, do i have to configure anything on the unity / exchange side of things, i have integrated the solution with unity connection and this works fine.
You have to enable IMAP on Exchange.
On Exchange 2003, the default port is 143 (IMAP). By default the service is disabled.
On Exchange 2007, the default port is 993 (IMAP over SSL). By default the service is disabled.
You also need to configure the Active Directory credential on CUPC > File > Preference > Account > Voicemail.
