By default, the busy tone compliant with the Europe standard is used.
This command applies to 2-wire loop trunk subscriber line FXO only. Once this
command is configured, the configuration will be effective to 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, only by
detecting the busy tone can the router know that the user has hung up. This is
made possible because different switches adopt different cptone schemes with
varying frequency spectrum characteristics, based on which the busy tone can be
identified.
