I believe that, as with ringers, there is a limit to the number of
caller ID devices you can put on the line and still have them work.
It is quite possible that, for the purposes of this question, modems
count as caller ID devices.

No, I don't know what that number is. Likely it depends on the
particular hardware, as with ringers, and the particular telco
equipment and wiring.

I'm sure someone else here will be able to provide a more
authoritative answer.
