Screen Displays COVM
The screen displays COVM when the COVM indicator is turned on for at
least one line, whether or not there are messages waiting, and whether or
not you have the service.
•
If you subscribe to Voice Mail service with your local telephone service
provider, but prefer not to display COVM on the screen, turn off the
COVM indicator for each line.
• If you do not subscribe to Voice Mail service, turn off the COVM
indicator for each line.
See “Turning COVM Indicators On and Off” in SET UP SYSTEM FEATURES.
COVM Line Indicator Remains On
• Make sure you have reviewed all messages on that line.
• You may have received a false signal from the Central Office. To clear,
see “Reset COVM Indicator” in CALLER ID OPERATION.
Incoming Calls Are Dropped By Auto-Attendant
Make sure you have recorded the Auto-Attendant Outgoing Messages and
your directory of extension assignments. (See ANSWERING SYSTEM
Auto-Attendant Operation.)
IN CASE OF DIFFICULTY

When you combine two or more 964 phones you create an interacting
system where phone share lines. You can have up to twelve phones and
up to 15 telephone lines. The 964 can be expanded with or without
Centrex service.
NOTE: All 964 features work as described earlier in this manual.
Line Groups
When phones share lines, Line-In-Use lights let users at different extensions
know when a specific line is in use. For accurate Line-In-Use lights, the
same lines must be connected to each extension in the Line Group, and
they must have the same incoming telephone number at each extension.
The chart below shows 12 extensions, each sharing the first three lines,
but being assigned to different Line Groups based on other shared or
private lines.
