Congestion( ) | Indicates congestion on the channel |
Congestion([ timeout ])
Requests that the channel indicate congestion and then waits for the user to hang up or for the optional timeout (in seconds) to expire.
This application only signals congestion; it doesn't actually play a congestion tone to the user. You can use Playtones(congestion) to play a congestion tone to the caller.
Always returns -1 .
