Call Timeout
The call timeout feature is used to limit the maximum duration of a call. The call timeout can be any
duration between one minute and 4 ½ hours. The duration is set in ½ second increments and the valid
range is from 120 to 32,400. To determine the value associated with a specific time duration, see the
example below.
*37
Data transfer command
<120~32400>
Call duration (120 to 32400 ½ seconds) – See example below.
#
End of string indicator
Example:
To determine what to enter for the call timeout duration, multiply the desired time limit, in minutes, by
120. For example, to determine the call duration entry for a call timeout of five (5) minutes, do the
following:
5 minutes
×
120 =
600
To enter a call timeout duration of five (5) minutes, enter the character string
*37600#.
When the call timeout duration has been successfully entered, the phone returns a system-generated
DTMF check-digit.
