Usage guidelines
The system supports four types of busy tone characteristics, which are specified by the index argument.
When detecting a busy tone on the FXO interface, the system automatically calculates the parameters
related to busy tone detection. You can use the display current-configuration command to display the
settings of these parameters.
After you use the vi-card busy-tone-detect custom command to configure the parameters related to the
busy tone detection, these parameters do not take effect immediately. The manually configured busy tone
parameters can take effect only after you execute the area custom command in voice view.
