That is what is
the difference between CUCM 6.1.3(b) and CUCM 18.104.22.16800
Hmm.. not that I've seen.
Basically there is the long form and the short form.
7.1(3) = 22.214.171.12400-11
Usually the 7.1(3) maps to the first three . separated digits, and then the initial version would have a number like 10000 followed by a build number or something... 3a would have 20000, 3b 30000.
7.1(3a) = 126.96.36.19900-2
7.1(3b) = 188.8.131.52000-1
Of course, anything after the 7.1.3 bit in these numbers is liable to pretty random (in initial 'a/b' releases and especially on anything in between such as service updates), so you can look up the version numbers in a couple of places:
