According to the docs...if you are using discriminator you do not 
need to hook up COR.. if you DO want to use COR...it requires a pull 
to ground as you noted.. by default. The pull can either be COR or 
NOT COR ..I think it was a command in the usb dongle configs.

I would let the dsp do the work... you only need the discriminator 
audio that way..

The notes look like it can handle more than one tone... but that is a 
question I am curious about too.... Especially if the tone used can 
cause a routing change on the internet..like the tone can trigger an 
automatic route selection.
