Hi guys,
We are testing kamailio with sipp. We are running it with 20cps and some calls do the following. When Kamailio is processing the 'ringing' a '200ok' arrives in the middle. First, kamailio forwards the 200 ok and then the ringing. 'ACK' arrives and, I suppose, the call is established. The thing is than when the 'BYE' arrives kamailio responds with a 404.
This is the summary of the call

We are using modules rtjson, evapi, uac, topoh, rtpproxy for all calls. My debug level is -1. With higher levels this behavior increase.
Kamailio is running in a virtual machine with centos7 with 8 cores and 8gb of ram.
Do you need any further information? I can send you a pcap or ngrep file.
Best regards,
Diego.
