Congestion() — Indicates congestion on the channel
Synopsis
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.

play a congestion tone to the user. You can use Playtones(congestion)
to play a congestion
tone to the caller.
Always returns -1
