Special Information Tone Detection

Hi All,

From what I can see, the subject of SIT detection hasnt been brought up in a while, and I would like to query those in the know about any progress made in this area. My company distributes asterisk boxes to small and medium size call centers who use them as dialers. The ability to detect and flag bad numbers and the like is a pretty major issue for us, and so far Im not finding any kind of a solution to it.

I realize that this is kind of a sticky problem for the Asterisk community, but is there ANYONE out there who has addressed this ?

Is it time to perhaps post a bounty to get this addressed and solved ?

Thank you for any information provided
