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.
