If you set the value of the Zip Tone Timer (secs) field to 2 seconds, Communication Manager times out after this time and plays a Zip tone.
If you set the value in the Zip Tone Timer (secs) field to greater than 2 seconds and less than or equal to 10 seconds, Communication Manager tries to terminate every member of the group page within 2 seconds. If the attempt is successful, Communication Manager plays the Zip tone. Otherwise, Communication Manager sets the timer for the remaining time. After the second timer times out, Communication Manager plays the Zip tone and does not wait for any member of the group page to answer the call.
For example, if you set the value as 6 seconds, Communication Manager tries to terminate every member of the group page within 2 seconds. If the attempt is successful, Communication Manager plays the Zip tone. Otherwise, Communication Manager sets the timer for the remaining 4 seconds. After the 4 seconds timer times out, Communication Manager plays the Zip tone.
The range for this field is 2 through 10 seconds, and the default value is 7 seconds. If you set the value of this field between 2 through 6 seconds, the system displays the following warning message: Group page may not reach all members with timer value less than 7 sec.
