Busy( ) Indicates a busy condition to the channel

    Busy([timeout])

Requests that the channel indicate the busy condition and then waits for the user to hang up or for the optional timeout (in seconds) to expire.

This application only signals a busy condition to the bridged channel. Each particular channel type has its own way of communicating the busy condition to the caller. You can use Playtones(busy) to play a busy tone to the caller.

Always returns -1.
