Recall/Switchhook Does Not Work - AT&T MERLIN LEGEND Release 3.1 System Manager's Manual

Recall/Switchhook Does Not Work

Recall/Switchhook Does Not Work
When this problem occurs, pressing the Recall button or switchhook
disconnects the call or fails to return dial tone.
NOTE:
If the telephone is an MLX or analog multiline telephone, pressing the
switchhook disconnects the call. On these phones, you must use a
programmed (on MLX telephones) or fixed (on analog telephones) Recall
button to activate custom or Centrex calling features.
Possible Cause 1: The Recall timer may be set incorrectly.
NOTE:
Some single-line telephones have a positive disconnect switch. If the switch is
set to positive disconnect, this Possible Cause 1 does not apply. If this is the
case, skip to Possible Cause 2.
What to do: Use system programming to check the setting of the Recall timer
system feature (see Chapter 3 in System Programming ).
If the setting is less than 650 milliseconds, change the setting to 650 ms
or to 1 second. Have someone place a call to the extension, answer it,
and press the Recall button or the switchhook. If you don't disconnect
the caller or you do get dial tone, you have solved the problem. If you do
disconnect the caller or you don't get dial tone, go to Possible Cause 2.
If the setting is for 650 ms or for 1 second, go to Possible Cause 2.
Possible Cause 2: The line may not have custom calling features.
What to do: Check with the central office (CO).
If there are custom calling features, obtain instructions on the use of the
features and the Recall timing.
If there are no custom calling features, go to Possible Cause 3.
Possible Cause 3: The telephone may be defective.
What to do: Test the telephone by replacing it with a similar telephone that you
know is working properly. Program the buttons as appropriate.
If the problem is resolved on the replacement telephone, then replace it
with the original telephone and check again. If the problem still persists
on the original telephone, then the original telephone may be defective.
Call the AT&T Helpline at 1 800 628-2888.
If the problem persists on the replacement telephone, there may be a
problem with the system wiring or the control unit. Call the AT&T Helpline
at 1 800 628-2888.
