callback.
The parameter user indicates that DCC will call back according to the parameter
configured in the
dialer route command. The parameter dial-number
indicates that DCC will call back the remote end according to the
callback-number
configured in the local-user command.
When both user and dial-number are applied concurrently, the router will first
attempt to place a return call according to the first parameter. If the callback attempt
fails, it will try the second parameter for callback
.
