Recall/Switchhook Does Not Work 8
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 do not disconnect the
caller or you do get dial tone, you have solved the problem. If you do
disconnect the caller or you do not 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.
