[SR-Users] Question on the SL Module

Hello Kama ML, today I stumbled on function "update_sl_stats()" inside sl_stats.c and noticed that some response codes are treated differently. For example here: https://github.com/kamailio/kamailio/blob/a9ef78b7f43616f2ceaa26df97eff68eb… since we have a "break;" statement, when a 500 code is received, the 5XX counter is not incremented even if a 500 code belongs to the 5XX family. We have the same behaviour for other response codes and it really seems that it's not a bug and the author really wanted it. The docs are not so helpful and they don't explain much in detail how counters are built. I just want to have confirmation this is how it must work and I wonder if it's the case to write something about it into the docs. Thanks Alessio
