Summary:                    [patch] DSP progress detection unable to detect SIT
Description: 
The DSP should be able to detect the SIT. The existing code checks for the
first tone followed by the second tone, followed by the third tone in
sequence and on detection of the third tone allows firing a CONGESTION
control frame.

This unfortunately doesn't work due to the fact that entire SIT is about 1
second long, the DSP is working with smaller samples and the code will not
stay in a second or third tone state beyond one pass.

This issue is being raised against trunk, but, the problem appears to be
present even in 1.2.
