Can someone explain how often the CUPC client synchronizes with the voicemail server? In my case, it's Unity Connection 7. You'd expect the envelope icon and number of messages to be in line with the number of new messages from the TUI or if viewed from IMAP. But CUPC seems to lag very far behind and the only way I've been able to force it to synchronize it to exit and relaunch the client. Is there a setting or a timer that can be adjusted?
