[sr-dev] 200 OK Retransmission Error

15 Jun 2011

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
