Congestion( )

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 .
