Usage guidelines
Once this command is configured, the configuration will be effective on all the analog FXO voice cards
on the device.
When an FXO interface card is connected to a common subscriber line of a program-controlled switch,
if the user on the switch side hangs up first, the router can know that the user has hung up only after
detecting the busy tone. Different switches might use different busy tone specifications. Use this command
to specify the applicable busy tone specification to correctly detect busy tones.
Examples
# Configure the busy tone type compliant with the North America standard.
