[asterisk-users] New tutorial: DTMF tone detection

[lenz]

Hello list,
I have prepared a small tutorial today that deals with how to avoid  
Asterisk rebuilding DTMF tones when using it to connect industial  
appliances that use DTMF. You can find it at:  
http://astrecipes.net/index.php?n=248

I know it isn't everybody's piece of cake, but I thought somebody could be  
interested as well :)
l.
