freq1 and freq2: Two frequencies in Hz. The frequency range is related to the 
combination mode. In the case of frequency superimposition or alternation, the 
two frequencies fall in the range of 300 Hz to 3,400 Hz. In the case of frequency 
modulation, the two frequencies fall in the range of 300 Hz to 3,400 Hz, and the 
sum of and the absolute difference between the two frequencies also fall in this 
range.

time1: Make time for the first make-to-break ratio in milliseconds, in the range of 
30 to 8,192. In the case of continuous play, the value is 8,192.

time2: Break time for the first make-to-break ratio in milliseconds, 0 or 30 through 
8,191.

time3: Make time for the second make-to-break ratio in milliseconds, 0 or 30 
through 8,191.

time4: Break time for the second make-to-break ratio in milliseconds, 0 or 30 to 
8,191.

index: Index of busy tone type, in the range of 0 to 3.

Use the vi-card cptone-custom command to configure parameters for a 
customized call progress tone.

Use the undo vi-card cptone-custom command to remove the configuration.

By default, no customized call progress tone is configured.

After you configure parameters for a customized call progress tone, they do not 
take effect immediately. They do only after you execute the cptone country-type 
CS command in voice view.

# Customize parameters for a busy tone, with the two frequencies both being 425 
Hz, and the make time and break time both being 350 milliseconds.

slot-number: Number of the slot where the voice card is located.

Use the vi-card reboot command to reboot a voice card.

First use command display version or display device to display the distributed
