Thanks Daniel for your response. Please find attached the "kamctl trap" output file, we were able to recreate that issue again. Traffics are not blocked as I can see messages are received on the kamailio listen interface by using sngrep tool. Also, the pike module is not in effect as WITH_ANTIFLOOD is not defined in the default configuration.
