Hi Daniel,
 
Thanks.. Is there any side effects if we increase the wt_timer to 32secs to match with the INVITE transaction timer?

regards,
Jijo

Hi All,

In an INVITE transaction, no ACK from A party and B party continue retransmission of 200 OK. I have observed that kamailio is not passing the retransmitted 200 OK message from B party to the Application(script) after 3 seconds. Instead kamailio directly sending to A party without passing to the script.
what do you mean "without passing to the script"?

Note that a transaction is completed when a final reply is forwarded back to the sender of request. Then it is kept fore a short time in memory, if you want to increase that interval, see this parameter in tm:

http://kamailio.org/docs/modules/stable/modules/tm.html#wt_timer

Cheers,
Daniel


I see in the logs that kamailio is cleaning up the transaction after 3 seconds..look for the string "DEBUG: t_lookup_request: no transaction found"  before this log it is cleaning up the timer in the log "DEBUG: cleanup_uac_timers: RETR/FR timers reset"

What does it mean by that??
How can we make the kamailio to pass the response to the application?

Please let me know your comments.. Here is the flow. I cannot send the complete logs which is quite big. so i grep'd using the stirng "tcp_read_req: content-length|get_hdr_field|t_reply_matching|cleanup_uac_timers|RR11" from the complete log..
