Hi All, We all like to be thanked and when someone does something for me, I like to show my gratitude towards them and I think what Anthony did for me today deserves a public show of gratitude. It goes like this: I have a single port FXO card in my home machine running FS and I needed to modify the tone_detect app so that it would not incorrectly detect busy tones during phone calls. If I call in and hang up on the remote end, FS would detect the busy tone and hang up correctly. The problem was that tone_detect would act as soon as it detected the requested tone (in my case, busy tone) so I might be in the middle of a phone call it would sometimes incorrectly detect a single busy tone and drop the call. I tried to ignore this at first but it started happening more often so I spoke to Anthony about the possibility of modifying tone_detect to have a "hit count" during a time window, so that it would have to detect X number of busy tones before hanging up the call. As you can all see, this is probably a minor issue on Anthony's priority list since there are many more important issues to fix or things to do on FS than fix tone_detect. Even so, he spent a good 6 hours on this issue and kept hacking at it until he got it fixed. Anthony, once again, fixing tone_detect really helped me but what I appreciate more than anything is the willingness to help and invest so much of your time on this .. so thank you once again! - Gonzalo (aka znoG) PS: I will soon update the wiki page http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect with details on how to use the hit count
