## Phenomenon： kamailio-0:


freeswitch:


The current problem is that the 180 and 200 responses are routed to another node and returned along the same route, but the node that received the invite request before cannot perceive it. I learned from the official documentation that dmq cannot replicate the response, so the current status is not synchronized, causing the first pod to send a 408 request to interrupt the session. This problem has troubled me for a month and I have no idea where to start. Please help
