[asterisk-biz] Ringing tone detection

[Lewis Chan]

It is quite common, some customer just want to see whether this is a valid 
Phone Number or Fax number.  by calling from 000000001 to 9999999.  After a 
valid number list is generated, they can perform tele-marketing and fax 
broadcast.

Subject: [asterisk-biz] Ringing tone detection

Hello,

We have a customer that asked us to develop a tool that could detect if
certain ringing tone is present in recorded audio. This looks like a part of
call progress analysis (CPA) functionality, and we are very curious is there
a big need in such tool, or it's a quite unique case. The idea is simple:

tool.exe audio.wav

and as result the tool says: Ringing tone #1 is present

or something like that.

Thank you very much for your attention to this post and ideas sharing!

Best Regards,
Sevana
