I have configured 7971-G-GE with manager features and shared line. On the shared line I have changed system notification to be blinking only. His secretary has regular settings and 7941 phone. We are using CCM 5.1.2 and Presence 6 server.
The problem is when anyone send message to 7971 phone, it arrives without any notification. The message is there, but we cannot see any notification. Not a sound, blink or any change on display!!! On all other phones it is working fine.
I do not what to do. On the phone I have configured audio notification ON.
