You can use a script based on "chat" like this one:

#!/bin/csh -f
while (1)
 foreach NUMBER (007 4711)
  chat\
  ABORT BUSY\
  ABORT 'NO CARRIER'\
  ABORT 'NO DIALTONE'\
  '' ATZ\
  OK ATDT${NUMBER}\
  CONNECT ''\
  ogin: ppbilly\
  sword: ruletheworld
  if ($status != 4 && $status != 5) exit $status
  sleep 1
 end
 sleep 60
end
