This is very easy: make sure that your "telephone system" sends RINGs
only to *one* modem at a time.  If that one is busy, use the next one.

Having all modems RING at the same time is a bad idea for obvious reasons
(locking, lots of failed calls, modem reinitialization dead time, etc.).

Effectively, make your telephone system view the modems as a "hunt group"
