Hi, an INVITE arrives to SR and the config script just executes:
sl_reply("404", "Bye Bye"); exit;
So no server transaction has been created. But when the ACK arrives it's correctly absorbed by SR transport layer (as it doesn't arrive to the script logic).
My question is: how does SR match such ACK? was some timer started to match and absorv the ACK?
Thanks a lot.

That is actually pretty clever. So is that what calc_crc_suffix() does?

Yes, calc_crc_suffix is used to generate SR-specific part of To tag.

Hi Jan, and which function is used to match ACK's Totag for statelessly generated [3456]XX final responses?
Thanks a lot.

It looks like it's done in sl_filter_ACK() in modules/sl/sl_funcs.c, which is registered as a pre-script/request callback in sl.c.
