Hi Gang,

One of our sites can't get ISDN, and the NXPhoneCall notification  
method "toneReceived:" is not supported for POTS in the Beta 3.0  
NeXTSTEP PhoneKit, so in order to receive touch-tones we have to be  
able to recognize them in the incoming data stream.

Does anybody out there have software to do DTMF recognition in 8-bit  
mu-law data that they can share?  This is just a temporary need for  
us until we get ISDN at all sites.  Thanks!
