If either the Timed Reminder on Hold interval, or the Return Call Timeout interval, expires before the call is answered, the call returns to the attendant console.
Procedure
Type change console-parameters. Press Enter.
On the Console Parameters screen, click Next until you see the Timed Reminder on Hold field and the Return Call Timeout field.
In the Timed Reminder on Hold field, type the maximum number of seconds that a call can remain on hold before the system alerts the attendant.
In the Return Call Timeout field, type the maximum number of seconds that a call can remain on hold before the call returns to the attendant.
Note:
You must allow at least 5 seconds for each ring at all points in a coverage path. This time ensures that the entire calling path is completed before the system returns the call to the console.
