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! --kyler
