Phone Does Not Ring
What to do: Turn off the Forward feature. Use one of the following methods,
depending on the type of phone:
At an MLX or analog multiline telephone with a programmed Forward
button, deactivate the feature and turn the light off by pressing the button
(if the green light is on, indicating that the feature is active). From another
extension, dial the extension where the problem is. If the phone now
rings, you have solved the problem. If the phone still does not ring, go to
Possible Cause 4.
At an MLX telephone without a programmed Forward button, deactivate
Forward by pressing the Feature button and dialing
extension number of the phone that is not receiving calls. From another
extension, dial the extension where the problem is. If the phone now
rings, you have solved the problem. If the phone still does not ring, go to
Possible Cause 4.
At an analog multiline telephone, deactivate Forward by pressing the
programmed Feature button and dialing
the phone that is not receiving calls. From another extension, dial the
extension where the problem is. If the phone now rings, you have solved
the problem. If the phone still does not ring, go to Possible Cause 4.
At a single-line telephone, deactivate Forward by dialing
extension number of the single-line telephone. From another extension,
dial the extension where the problem is. If the phone now rings, you have
solved the problem. If the phone still does not ring, go to Possible
Cause 4.
Possible Cause 4: The Ringing Options Ring Timing feature for the extension is
programmed for No Ring or Delayed Ring.
What to do: Use centralized telephone programming or extension programming
to check the Ringing Options setting for the extension (see Chapter 5 of System
Programming ).
NOTE:
You can check the Ringing Options setting at an MLX display telephone by first
pressing the Inspct button and then a line button. Ringing can be set for each
line or for all lines. To change a setting, use extension programming. At an
analog multiline or single-line telephone, check the Ringing Options settings for
each line by using centralized telephone programming.
If the Ringing Options setting is No Ring or Delay Ring, change the
setting to Immediate if appropriate. From another extension, dial the
extension where the problem is. If the phone now rings, you have solved
the problem. If not, go to Possible Cause 5.
If the Ringing Options setting is Immediate, go to Possible Cause 5.
