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.

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..

A kamailo B
