1) I appreciate the response for the DTMF decoder request - especially the
ring signal suppressor!

2) Any ideas on _creating_ a ring signal?  I'm trying to route an incoming
call to a device.  I've found out that a 'standard' ring is 48vdc @ 20Hz.  How
close to this must I get?  It would be great if I could use 60Hz, but I doubt
that's a good option.  (I have little knowledge of analog electronics.  Alas,
another CS major trying to do EE...)

Thanks!
