[sr-dev] match e2e proxied ACK Request when INVITE Transaction is still in memory

[Henning Westerholt]

Hello,

as mentioned, alternative would be dialog module. I do not remember if it already matches early dialogs, but probably yes:

Cheers,

Henning

Hello,

yes i was talking about the ACK for the 200 OK.

I just want a way to check that an ACK is effectively matching dialog information ( Call-ID,Cseq,From-tag,To-tag ) for an invite that has passed through my kamailio.

i dont see another solution if not store those dialog information in htable and do the check for the E2E ACK when it comes later.

Thanks.

Hello,



not sure if I got your question correct. If you are referring to the ACK that is send to a 200 OK on an INVITE transaction, this is a separate transaction. Therefore, you cannot match it on the transaction manager level. The dialog module provides dialog tracking, for example.



Cheers,



Henning

Hello ,



i want to know how can i match e2e ACK when the INVITE TRansaction is still in memory.



t_check_trans() normally return 1 if we receive e2e ACK but i always get 0 even when the INVITE transaction is still in memory ( wt_timer param of tm module ).



Thanks.
