### Description
we are using rtpengine with kamailio [KSR-LUA]. kamailio sending the rtpengine_offer to
rtpengine. If kamailio didn't get the response from the rtpengine then it's not
retrying . for rtpengine_answer and rtpengine_delete retry is working pretty good.
we are using following rtpengine configuration
# ----- rtpengine params -----
modparam("rtpengine", "db_url", DBURL)
modparam("rtpengine", "table_name" , "rtpengine")
modparam("rtpengine", "rtpengine_allow_op", 1)
modparam("rtpengine", "queried_nodes_limit", 4)
modparam("rtpengine", "rtpengine_retr", 2)
modparam("rtpengine", "rtp_inst_pvar",
"$avp(RTP_INSTANCE)")
modparam("rtpengine", "setid_default", 1)
modparam("rtpengine", "rtpengine_tout_ms", 400)
