Yes there are some differences between modern and ancient usage of Roman numerals and the following gives a very brief explanation:
Modern:
Units from 1 to 9: I, II, III, IV, V, VI, VII, VIII, IX
Tens from 10 to 90: X, XX, XXX, XL, L, LX, LXX, LXXX, XC and 100 = C
To select a number write out the tens first then followed by the units.
Examples: XV = 15, 49 = XLIX, 99 = XCIX
Ancient:
Units from 1 to 9: I, II, III, IIII, V, VI, VII, VIII, VIIII
Tens from 10 to 90: X, XX, XXX, XXXX, L, LX, LXX, LXXX, LXXXX and 100 = C
To select a number do the same as the above, first the tens followed by the units.
Examples: XV = 15, 49 = XXXXVIIII then simplified to IL, 99 = LXXXXVIIII then simplified to IC
There is strong evidence that exist today that thoroughly supports the fact that the latter mode of writing out Roman numerals was used by the Romans themselves rather than the former mode.
In todays modern notation of Roman numerals it is LXXXIX = 89 but in ancient times it would have been LXXXXV = 95
Hindu Arabic Numerals use numbers but Roman numerals use symbols.
Since the question does not specify what the ancient telephone with, I shall compare it to a fish. The 5 differences between an ancient telephone and a fish are: The ancient telephone was a man-made device, the fish is not. The ancient telephone was used for communication, the fish is not. The ancient telephone can survive longer outside of water, a fish cannot. The ancient telephone was not alive, a fish is. The ancient telephone had a mouthpiece, a fish has a mouth.
XLII is 42 in Roman numerals. XXXIV is 34 in Roman numerals. The difference between them is 8, or VIII in Roman numerals.
Leibniz's contribution was more on developing the theoretical basis and the notation whereas Newton's was more in its application.
