[OpenSIPS-Users] s.index madness and my waning grip on sanity

Hi, Jock!

The answer is simple: you must be using a pre-2.2 OpenSIPS, which does 
not include this transformation, just like the error message says:

"ERROR:core:tr_parse_string: unknown transformation: index"

Future advice: before reading documentation, make sure you properly 
select your OpenSIPS version using the top-level switches [1]
