Hi Guys,

I'm having trouble with my ACK's on 2xx, and reading about the TM-module,
it says for t_check_trans() :

ACK request - true if the ACK is a local end-to-end ACK for an existent INVITE transaction.

To me, that sounds like a contradiction in terms, since there is (rfc-wise) no transaction left after
2xx has been proxied through, and the ACK starts coming in(because of record-routing).
(and my script's ACK-logic for consuming ACK for 3++ also eats the ACK for 2xx :-( )

Does the TM module not follow the rfc-described termination of invite-txn's?

Then how long does the transaction live after 2xx has been forwarded?
How come its implemented this way?

If this is so, then how do I differentiate between an end-to-end ACK for 2xx, and a 3++
hop-by-hop ACK?
I have to use flags and stuff? (Havent got that far yet in my openser understanding...)
