Hummm, I'm surprised this actually works.  Those Radio Shack boxes
tend to "absorb" 1/2 to 1 ring if it has to actually do the switch to
the "other line".  Since the Caller-ID is sent between the first and
second ring, I would expect this information to be lost in any cascade
arrangement that actually has to do more than one level of switching.
