Customer is running CCM 4.2(3)sr1 and Unity 4.0(4)sr1. There have been a few reports recently where the calls go directly to the greeting instead of ringing the extension. Each time, I looked in Unity > Subscribers > Call Transfer > Transfer incoming calls to subscriber's phone? and it is set to "No (send directly to subscriber's greeting)". This has happened on a few different users and the users would not know how to change this either through the TUI or GUI. They may have accidentally changed it through the TUI, but very doubtful as they don't even go into the settings to change things.
To resolve the issue, I simply go into saweb and set the option back to "Yes, ring subscriber's extension".
I've never heard of Unity changing this automatically. Any suggestions on where to look as to what would switch that setting?
