Greetings,
How much time will Kamailio keep a transaction active if the ACK to a INVITE is never received by Kamailio?
Best Regards,
Hello,
is it about ACK after 200ok or the ACK after 300 or greater reply?
Cheers, Daniel

It is after the 200 Ok. Will it be different in a reply greater than 300?

By default the transaction that gets a final reply is kept for another 5sec or so in memory to deal with retranmissions, etc ... There is a wait_timer parameter in tm module.
The ACK after 200ok is separate transaction and has no influence on INVITE transaction. For the ACK after 300+ reply, there should be some retransmissons of the reply in the INVITE transaction.
The dialog module is influenced by the missing ACK after 200ok.
Cheers, Daniel

Thanks for the reply.
Here is my scenario :
Client________Kamailio______Destination_1____Destination_2 |_____INV_______|_______________|_______________| |---------------------->|______INV______|_______________| |_______________|---------------------->|_______________| |_______________|_______________|_______________| |_______________|____200_OK_____|_______________| |_______________|<-----------------------|_______________| |____200_OK_____|_______________|_______________| |<-----------------------|_______________|_______________|
|_______________|_______________|_______________| |___INV(Retr)____|_______________|_______________| |---------------------->|______INV______|_______________|
|_______________|------------------------------------------------>|
|_______________|_______________|_______________|
As you can see, the client never sends the ACK to Kamailio and retransmits the first INVITE (No To-TAG) again after more than 5s. After this Kamailio uses Dispatcher to send to a destination from a group and chooses Destination_2.
Since the INVITE is sent to Destination_2, my system treats this as a second call being created.
Should this scenario happen under the SIP stack rules? Shouldn't Kamailio send a "491 - Request Pending" on this scenario?
If not, how i can configure Kamailio to behave like that? In my code i have the following conditions for a Request to able to be sent by DISPATCHER :
- if( is_method("INVITE") && !has_totag() )
- if(!t_check_trans())
What other conditions can i setup in order for this INVITE to be treated like a retransmission or being rejected?

Last email diagram got kinda deformatted. In case you need me to clarify the scenario, client sends the INVITE, receives the 200 OK and never send the ACK. After more than 5seconds the client retransmits the first INVITE again and Kamailio sends it to the second destination of the Dispatcher group.
