Registration is not working when Rx is on

[deepak-git-account]

Hi,
I am working to integrate Kamailio IMS Server with my EPC project.. Registration is not completing when Rx interface is on.
As per my understanding, after receiving 200OK for the registration, PCSCF is not able to forward this towards UE and the reason looks related with Async setting of Rx messages. How we can proceed in this case?

packet number 7953.
I am using latest code of kamailio.

I am using latest code of kamailio.

Can you elaborate on what you mean by latest code of kamailio? Is the forked branch which I maintain or is it the master branch of kamailio repo?

Also, please always describe your setup like is EPC running in a different machine than IMS etc and attach a pcap trace of the registration in order to debug. Just a screenshot will not help.

Thanks for reply.. I am using master branch kamailio repo 5.7.2.
EPC and Kamailio IMS Server are using different m/c. Could you please help here as well?

Hey, I had a look and was not able to figure why 200 OK was not forwarded to P-CSCF.

Also, I haven't test the configuration in this repo with upstream kamailio repo for version above 5.3 so I would suggest raising the issue there
