Busy()

Sets the channel as "busy".

        
          Busy([timeout])

Instructs the channel to indicate busy and waits until the caller hangs up or the timeout expires (timeout, in seconds).

This application indicates a busy state only on the bridged channel. Every channel type has its own way of indicating that a device is busy. To play an actual busy tone, use Playtones(busy).

Always returns -1.
