Hello, Someone previously had mentioned the Rat Ring site as a source for information regarding interfacing a PIC with a private telephone network. Unfortunately, it seems that the website for Rat_Ring does not directly link to any schematics, or archives of the mailing list for them. The yahoo group for rat_ring apparently has this information, but you must be a member in order to look at it (and my membership is currently pending, and must be approved by a moderator). So, I was wondering: * What other sources of schematics, and information is there for interfacing a PIC with a private telephone network.. I searched via google, but I have had limited luck finding anything useful for this. If someone else knows of any other resources, that would be great. * Does someone maintain a public copy of the rat_ring's mailing list archives, since I can't view them as I haven't been approved by the moderator for the rat ring yahoo group as of yet.
