PhoneSoft can run in an RS/6000 environment. However, since the RS/6000 runs the IBM AIX (UNIX) operating system, and PhoneSoft software runs on Windows NT, PhoneSoft must run in a separate NT box from the RS/6000. But since PhoneSoft supports users mail files (and any other Notes databases) being on any Notes or Domino server (including the RS/6000), PhoneSoft works completely in an RS/6000 environment so long as PhoneServer is running on an NT PC. .
